The arc tube is made of aluminum oxide and the sodium metal is combined with several other elements like mercury which counter-balances the yellow glow with some white to light blue emissions. LED dimming functions by either lowering the forward current or modulating the pulse duration. They produce a dark yellow glow which is generally a very low quality light. The lights become less efficient over time because they must use more and more voltage to produce the same lumen output as the light degrades. The spectrum of visible emissions from an LPS light is actually very close together (589 and 589.6 nm, virtually monochromatic) resulting in the colors of illuminated objects being nearly indistinguishable. Most values for LED system efficiency fall above 50 lumens/watt. We are going to tackle the question which light bulb type reigns supreme? Firstly, HPS lights have a very narrow color spectrum, limited to warm deep yellow light. Horticulture Lighting Group HLG 650R (Best Overall) This light is the latest powerhouse grow … If you have any information please, Energy Service Companies (ESCO)/Contractors. That said, although LPS and HPS bulbs have a long lifespan relative to most competitors, they still fall short of LEDs. You can read more about the impact of directional lighting by learning about  a measurement called “useful lumens” or “system efficiency.”. (a device that converts visible light into electrical current). Induction has, I think lost it's momentum.So a new LED system would save tons of electricity and take fewer fixtures to light the existing area. The major payback comes primarily from reduced maintenance costs over time (dependent on labor costs) and secondarily from energy efficiency improvements (dependent on electricity costs). Incandescent bulbs and CFL bulbs are more easily broken than LEDs, which increases their cost of use. LEDs emit light for 180 degrees. According to American Electric Lighting, “HPS lamps still generate 90% of their initial light output at the midpoint of their life span. Low and High Pressure Sodium lights are the only light whose source efficiency compares to LEDs (values range between 50 and 160 lumens/watt for LPS and slightly less for HPS). at certain voltages, current levels, or light intensities). These include the following: Considering the upside you might think that LED lights are a no-brainer. It can take up to 10 minutes to get the LPS or HPS lamp up to its normal operating temperature. When current passes through the semiconductor material the device emits visible light. We specialize in researching, manufacturing, and customization of LED light fixtures. Over the years, advances in technology have brought about innovations in how to light our homes and commercial buildings. Consistency. The sodium can catch fire even in the event that the lamp is broken on the ground. The technology pays the investor back over time (the payback period). Starting is relatively simple with small tubes but can require significant voltage with larger lights. (Don't give up if you received an expensive proposal to upgrade to LEDs. This is especially true of those bulbs in linear tubes. When comparing different light bulbs and lamps, it is better to compare the lumens that each bulb produces, in order to gain a true like-for-like comparison. absorbed by the ballast and/or lost to the environment. Although they are very popular for street lights, they don’t serve many other applications. On a quest for the best lights for growing cannabis? 70 watt HPS = 40 watt LED; 100 watt HPS = 50-60 watt LED; 150 watt HPS = 80-90 watt LED; 250 watt HPS = 90-125 watt LED; As you can see, LED lights use far less energy to produce light of a much better quality. Although sodium vapor lighting beats virtually every other technology in terms of energy efficiency (which is why it was chosen to illuminate the streets of so many cities), it loses out to LEDs. Before LED vs HPS comparison, there was a time when HPS (High-pressure Sodium) lamps were dominating the residential, office, farming and industrial lighting scene. The popularity of that technology is not just due to its energy efficiency. The downside is that there are very few options outside the narrow range to choose from. LEDs are fine for all normal operating temperatures both indoors and outdoors. Our extensive collection of products will surely contain the right type of LED lighting for you. Also, LEDs waste less energy producing waste heat, resulting in longer life and the best energy efficiency. The typical lifespan for a fluorescent bulb, by comparison, is 10-25% as long at best (roughly 10,000 hours). Specialized in outdoor and indoor lighting products such as silicon led neon light, led strip light, LED floodlight, LED linear light, led corn light, led parking lot light, led ufo high bay etc with DLC/UL/CUL/CE/ROHS certification... Read More, Building A,Second Industrial As indicated by the name, “high” pressure sodium vapor lights operate at a higher internal pressure. Do you plan to undertake that long-postponed high pressure sodium to LED conversion for the lighting in your home or office? High Pressure Sodium lamps emit visible light across a slightly more broad spectrum than Low Pressure Sodium lamps, they are still very limited. I know that you have an opinion, I certainly did! LEDs have an extremely long lifespan relative to every other lighting technology. See the chart below to see an example of a LED spectral chart: To get you more familiar with LED grow light spectral charts for different phases of growth, below we have the HLG 300L Rspec (flowering phase/full cycle) and Bspec (vegetative phase) so you can compare them. . Comparing 90w LED UFO with different configurations to a 400w HPS and other factors. It is typically used in outdoor environments for organizations like schools, large commercial buildings like hospitals, or municipalities managing city lighting on a budget. The bottom line is that having lost their traditional advantage of being the most energy efficient bulb on the market, there’s very little reason to use a sodium vapor light when LED lighting is available. In particular, LED lights are relatively expensive. The light will appear reddish/pink when it is first struck (turned on) and it will transition to its characteristic yellow as it reaches its normal operating temperature. Additionally, as the light heats up it requires additional voltage to operate which is balanced by a ballast (a magnetic or electric device designed to provide the light constant current). LEDs are popular because they ar… Thankfully, the market has changed a lot since due to their high power consumption, short lifespan, and environmental drawbacks. Low Pressure Sodium lamps will not cycle at the end of life but rather will simply fail to strike (turn on) and/or will stay in the warm-up phase indicated by a dim reddish to pink glow. The Grow Closet. HPS bulbs typically emit 80% of their original rated output at the end of life (around 24,000 hours). This is typically an advantage because light is usually desired over a target area (rather than all 360 degrees around the bulb). They produce steady light without flicker. Diodes are generally made from semi-conductive materials such as silicon or selenium - solid state substances that conduct electricity in some circumstances and not in others (e.g. In other words, if you’re not looking for a warm deep yellow light, you’re going to have to use something besides Low or High Pressure Sodium to achieve it. The downside is that there are very few options outside the narrow range to choose from. It is particularly useful for outdoor lighting where energy efficiency is at a premium (such as with municipalities lighting the streets or other common areas like parking lots.) All in all this makes the applications in which LEDs can be used extremely diverse. You can, about the impact of directional lighting by learning about  a measurement called “, We couldn’t find any objective data on fluorescent bulb performance in high temperature situations. For this reason LPS lights are actually desirable as they minimize electromagnetic interference near facilities conducting astronomical observation. Foot candle is a measure that describes the amount of light reaching a specified surface area as opposed to the total amount of light coming from a source (luminous flux). They reach maximum brightness near instantaneously. Commercial Lighting, Parking Lot Lighting, LEDs have a light spread of 180 degrees, and so more light is actually directed towards the subject in question. LED lifespan can be greater than 100,000 hours (more than four times that of LPS or HPS). Stouch Lighting Services, Do LED grow lights yield more? Watch time lapse footage with real results. The extremely low maintenance and replacement costs with LEDs is actually a major cost benefit over the long term. In particular, they have been known to start fires in the event that the lamp is broken and the sodium metal is exposed. So if I get one 300W LED grow light panel, it would be a safe assumption that it … LED has virtually zero maintenance costs and the frequency with which bulbs have to be changed out is by far the best on the market.

LEDs Superior Operating Life. Well here’s a head-to-head comparison of the two followed by an in-depth discussion of each technology in turn. In some circumstances heat emissions could be beneficial, however, it is a generally a bad thing to emit heat as it represents an energy inefficiency. LPS or HPS lights will still likely need to be purchased several times and the associated labor costs will need to be paid in order to attain the equivalent lifespan of a single LED light. Lighting Comparison: LED vs Metal Halide Lights Most people would really like to see the comparison if possible. Although. The difference is that sodium vapor lights were the most efficient technology of the 1970s while LEDs are the modern day equivalent. Lumen maintenance at the end of life still is excellent at around 80%.” LPS lights last slightly shorter periods of time (typically failing around 18,000 hours of operation). Since then they have gradually expanded their applications to include traffic lights, lighted signs, and more recently, indoor and outdoor lighting. Bulb breakage and bulb replacement costs have not been factored into this comparison chart. Sodium vapor bulbs contain metals that are evaporated into inert gas within the glass casing while LEDs are a solid state technology. In other words, if you’re not looking for a warm deep yellow light, you’re going to have to use something besides Low or High Pressure Sodium to achieve it. HID vs. This is by far the biggest downside that needs to be considered. In some cases (particularly with older HID bulbs) dimming can cause the light to prematurely expire. In the beginning, all we had was the standard, incandescent light bulb. The mercury inside the bulbs is a hazardous material that can present a waste disposal issue at the end of light’s life. Low and High Pressure Sodium bulbs are fragile relative to LEDs. Is LED more efficient than HPS? The need for reflection and redirection of light means that the output is much less efficient for omnidirectional lights due to losses than it would be for the same light if it were directional by its nature. Advantages and Disadvantages of LED Lights, IP64 DC12/24V High Lumens LED Corn Light Bulb, 480V 347V 200W Led Corn Cob Lamp with 26000 Lumens, 150W Led Corn Lights For High Bay Fixtures. Low and High Pressure Sodium Lamps come in all shapes and sizes but are typically used for outdoor applications where size isn’t a major factor. So, if you need help with your high pressure sodium to LED conversion, MastLED is here to help. Low and High Pressure Sodium lights are very cheap to purchase as well as fairly cheap to maintain. The lightbulb lumens to wattage chart below will help you understand which LED bulb is comparable to your current incandescent bulb. Not too long ago, Access Fixtures was contacted by a property owner seeking to upgrade her outdated 250w, 2100K, high pressure sodium (HPS) wall packs to LED wall packs. Low and High Pressure Sodium lights require a warm-up time that varies depending on the light. Simply take your current incandescent watts and select the corresponding LED bulb equivalent on the lumens brightness scale. That said, HPS lights in particular maintain fairly good light output (roughly 80%) at their typical end-of-life (24,000 operating hours). The principal difference between low and high pressure sodium lights is the operating pressure inside the lamp. It is very much the opposite of a photovoltaic cell (a device that converts visible light into electrical current). This means they emit light for 360 degrees, requiring fixture housings or reflectors to direct a large portion of the emissions to the desired target area. Sodium vapor lighting has been around since the middle of the 20th century (in commercial production since the 1930s) and it generally represents a high efficiency way to provide lighting over a vast area. Several other web sites claim to compare LED grow lights, with lists of the “best LED grow light reviews of 2015”, but these have no explanation of how these “best” choices were made or even what lights were examined. Needless to say, converting from HPS to LED is definitely something you should consider for your home or office. Ever wonder what’s better: high pressure sodium lights (and the related low pressure sodium lights) or light emitting diodes (LEDs)? HPS light setups have a cheaper initial start-up cost, but the price gap between comparable HPS and LED grow has become much smaller as LED grow light setups have become more and more affordable each year. Having to purchase one bulb versus three or four bulbs over the course of time is a significant selling point for LEDs. Typical lifespan values for an HPS bulb are around 24,000 hours. The overall performance drop is relatively low over time with around 80% output being normal near the end of life. This is typically an advantage because light is usually desired over a target area (rather than all 360 degrees around the bulb). LPS lamps emit a monochromatic yellow light which very much inhibits color vision at night. When comparing both technologies, always compare light levels of the entire grow and not just fixture to fixture. Even so, they typically aren’t produced below roughly a centimeter in width and so they do not compare to the small size and robust build of a solid state light like LED. Typical source efficiency ranges 37 and 120 lumens/watt. Sodium lights operate in a range where the human eye is very sensitive and so there is less power required to achieve the same lighting effect. Low Pressure Sodium lamps are notorious for having the worst CRI values on the market. Additionally, HPS lamps pose a potential fire hazard, especially when you dispose of them. There are four major advantages to LED lighting: In addition to the major advantages, LED lights also offer several smaller perks. are notorious for having the worst CRI values on the market. Our value engineering service can help.). The light doesn’t arrive at full power until the salts are fully evaporated into plasma (which can sometimes take up to 10 minutes). LEDs are available in a wide range of color temperatures that generally span from 2200K-6000K (ranging from “warm” yellow to light or “cool” blue). Gongming, Bao’an District, It is only recently with the advent of affordable and prevalent LED lighting that they are being consistently surpassed in terms of energy efficiency and lifespan. As mentioned, the operating life of a typical Metal Halide bulb … As sodium vapor lights age, more and more voltage is required to produce the same amount of light until eventually the voltage exceeds the fixed resistance provided by the ballast and the light goes out (fails). A LED lamp uses 30 watts quite differently from an HPS one. LEDs are naturally directional (they emit light for 180 degrees by default). The difference between led vs hps lumens per watt is greater because there's less "loss" of light. Molestiae reiciendis neque arcu! Low and High Pressure Sodium bulbs are long lasting but will still require replacement several times in addition to the labor cost to monitor and replace aging or expired components all within the lifespan of a single LED. Both technologies are very efficient. Before ing grow lights led versus hps color spectral impact area roadway hid to led equivalency lumens to watts conversion chart for Hid To Led Conversion Chart 14 TableHow Many Lumens For A 400watt Metal Halide And What Is The Led EquivalentHow To Find Led Equivalent Wall Packs Replacing HidsHid To Led Conversion Chart 14… Read More » LED Retrofit, Disadvantages of High Pressure Sodium. LPS and HPS lights are much more efficient as well as longer lasting than incandescent bulbs, many fluorescent bulbs, and most high intensity discharge lamps in general. HPS lamps are better but are still surpassed by virtually every other light on the market. HIDs are very efficient compared to CFL and incandescent lights (120 lumens/watt source efficiency). High Pressure Sodium lights maintain their luminescence fairly well with 90% still available halfway through their lifespan (around 12,000 hours). Find the Right LED … LPS lamps emit a monochromatic yellow light which very much inhibits color vision at night. LPS and HPS still retain these advantages over most conventional bulbs but they lose on all three counts to LEDs. Both low and high pressure sodium lights require ignition which is typically provided by a voltage pulse or a third electrode (an additional metal part) internal to the bulb. Problems with the starter and/or improper matching of a starter and an HPS lamp may cause cycling even though the starter is otherwise working properly as the lamp is continually trying to light itself. The up-front costs of an LED lighting project are typically greater than most of the alternatives. LEDs emit very little forward heat. High pressure sodium vapor (HPS) lights, similar to LPS lights, are a specific type of gas-discharge light (also known as a high intensity discharge, HID or arc light). LEDs emit light for 180 degrees. They are also adaptable for large public areas (which require powerful, efficient lights over a large area), road lighting (which offer significant color advantages over low and high pressure sodium lights), and parking lots. Topics: Retail Lighting, If you have any information please contact us. Wall Pack Lighting, They lose out to LEDs principally because their system efficiency is much lower (<30 lumens/watt) due to all of the losses associated with omnidirectional light output and the need to redirect it to a desired area. For an interesting take on the history of street lighting in the United States read here. While this is increasingly becoming the case, there are still a few tradeoffs that need to be made when you choose LED: In particular, LED lights are relatively expensive. Click edit button to change this text. LED is the newest and by far the best lighting technology available, using less wattage to produce high levels of brightness. You’ll note the light intensity hardly fades at all on the Spider Farmer compared to the older boxy purple LED grow lights. Like most legacy lamps HPS and LPS lamps operate by using a glass bulb. Low pressure sodium vapor (LPS) lights are a specific type of gas-discharge light (also known as a high intensity discharge, HID or arc light). Much like fluorescent lights, modern LED lights are a wonderful solution for gymnasiums, warehouses, schools and commercial buildings. A recent addendum to the original report examined LED street lights that could match the pole spacing provided by incumbent 150W HPS street lights. So, to illustrate our point, let’s have a look at our HPS to LED conversion chart. 100 Degrees Celsius. LED means Light Emitting Diode. Additionally, despite their long warm-up period (5-10 minutes), low pressure sodium lamps will re-ignite immediately in the event of a power interruption. Are they equivalent?How do we conduct the ultimate grow light review? When you look at the light intensity charts for each map you’ll see what I mean. I cannot stress enough that there is no such thing as a 1-for-1 replacement of HPS by LED! Additionally, there are serious waste disposal issues with sodium lamps. LED light costs are high but variable depending on the specifications. Lumen Comparison Chart. The ultimate purpose of the device is to emit light, not heat. You can get in touch with us 24 hours a day, 7 days a week. Low and High Pressure sodium lights produce a very narrow spectrum of light (particularly LPS lights). Broken bulbs release a small amount of toxic mercury as a gas and the rest is contained in the glass itself. For this reason they are very efficient. All High Intensity Discharge lights (of which HPS and LPS are examples) emit light omnidirectionally. Much like fluorescent lights, modern LED lights are a wonderful solution for gymnasiums, warehouses, schools and commercial buildings. Typically they fall around 25 on a scale of 100 where 100 is the best possible. Sodium vapor lighting typically requires a “warm-up” period in order to evaporate the internal gas into plasma. These diodes can emit red, blue or green light, and most grow lights offer a balance of the three to mimic natural light. Most values for LED system efficiency fall above 50 lumens/watt. Snow falling on traditional lights like HID will melt when it comes into contact with the light. LED stands for light emitting diode. Tempor reprehenderit accusantium quibusdam iste accusan. Growers endlessly speculate and debate which is better for plant growth. Only) $ $230.00 $475.00 Fixture Installation (Labor) $ $29.00 $29.00 Manufacturer's Lamp Life Hours 20,000 50,000 Annual Energy Costs $ $72.36 $32.88 Lamp Replacement Cost $ $1.20 per month $0.60 per month* Since then they have gradually expanded their applications to include traffic lights, lighted signs, and more recently, indoor and outdoor lighting. Park, No.2-3 South Road, Mastled Lighting Technology CO LTD specializes in researching, manufacturing and customization of LED indoor and outdoor light fixtures since 2008, with monthly output of over 50,000 lamps. They are also adaptable for large public areas (which require powerful, efficient lights over a large area), road lighting (which offer significant color advantages over low and high pressure sodium lights), and parking lots. Red is the ideal spectrum for stem growth, flowering and fruiting. Now we have compact fluorescent lamps (CFL) and light emitting diodes or LED for short. Lighting Education, This is by far the biggest downside that needs to be considered. The typical 100W-equivalent LED light costs somewhere between $10 and $20. Indeed, high pressure sodium (HPS) lights are generally unmatched in terms of energy efficiency. Back in the day, more wattage meant more brightness. Kind LED say you can. Comparison Chart HPS vs. lifespan) they are drastically inferior to LEDs. LEDs produce a very narrow spectrum of visible light without the losses to irrelevant radiation types (IR, UV) or heat associated with conventional lighting, meaning that most of the energy consumed by the light source is converted directly to visible light. LPS lamps in particular are monochromatic which means that the objects illuminated by them appear shadowy black rather than the color you would see during daylight. The largest selling point of LPS and HPS lights is the cheap selling price, the high energy efficiency (low operating costs), and the relatively long lifespan. Yes, there are LED fixtures that exist when measured directly beneath the fixture. Minus 40 Degrees Celsius (and they will turn on instantaneously). (Don't give up if you received an expensive proposal to upgrade to LEDs. So, to illustrate our point, let’s have a look at our HPS to LED conversion chart. During start (while the sodium is still in solid form) the lamp emits a dim reddish/pink glow. Any defective LED bulb will usually fail within this time. LED vs High Pressure Sodium. CRI for LED is highly dependent on the particular light in question. Our, The first practical use of LEDs was in circuit boards for computers. LEDs fail by dimming gradually over time. As you can see, LED lights use far less energy to produce light of a much better quality. Omnidirectional lights produce light in 360 degrees. LEDs are very efficient relative to every lighting type on the market. It also means that more accessory parts are required in the light fixture itself in order to reflect or focus the luminous output of the bulb (thus increasing unit costs). High Pressure Sodium lights have excellent lifespan as well (although not as good as LED) which is why they have traditionally been used for outdoor street lighting in municipalities where energy efficiency is at a premium. Correlated Color Temperature (read more here). Lorem ipsum dolor sit amet, Mastled established in 2009 and located in Shenzhen China. Nowadays, however, the situation is drastically different. The uniform light coverage is perhaps the best characteristic of Spider Farmer grow lights and other quantum board grow lights. Although High Pressure Sodium lamps emit visible light across a slightly more broad spectrum than Low Pressure Sodium lamps, they are still very limited. Phoenix: HPS to LED Conversion Analysis Data (Arterial street) Units HPS - 250 Watt LED - 139 Watt Lamp and Fixture (Mat. The bulb principally contains solid sodium metal inside a borosilicate glass tube that vaporizes once the lamp is turned on. They do, however, show degraded performance at significantly high temperatures and they require significant heat sinking, especially when in proximity to other sensitive components. LEDs are an ideal light for purposely turning on and off because they respond rather instantaneously (there is no warm up or cool down period). LEDs are very easy to dim and options are available to use anywhere from 100% of the light to 0.5%. Typical source efficiency ranges 37 and 120 lumens/watt. Metal Halide / High Pressure Sodium to LED Wattages Conversion: Original Lamp: LED Lamp: 70 Watt Metal Halide: 30 Watt LED: 100 Watt Metal Halide: 40-50 Watt LED: 150 Watt Metal Halide: 60-70 Watt LED: 175 Watt Metal Halide: 80-90 Watt LED: 70 Watt High Pressure Sodium: 40 Watt LED: 100 Watt High Pressure Sodium: 50-60 Watt LED: 150 Watt High Pressure Sodium: 80-90 … Lifespans are variable but typical values range from 25,000 hours to 200,000 hours or more before a lamp or fixture requires replacement. The current unit for measuring brightness is the lumen, which represents the amount of light produced by a bulb or a lamp. Foot candle is a measure that describes the amount of light reaching a specified surface area as opposed to the total amount of light coming from a source (luminous flux). LEDs are solid state lights (SSLs) that are difficult to damage with physical shocks. Typically they fall around 25 on a scale of 100 where 100 is the best possible.
