Huge advancements in this technology allow for a very efficient LED that can produce a rainbow of colors (unlike narrowband LEDs) by using a “phosphor”. When I first started growing, I made the mistake of looking into articles that boldly declared a winner between MH vs. HPS, LED vs. MH, CFL vs. HPS, and HPS vs. Can you figure out the special ability that infrared light (700nm) has when it is combined with red light (680nm)? Are you planning to get into indoor gardening and you are torn between going for LED Vs HPS grow lights? This means less cooling of the grow space and a far lower chance of plant burn – especially when it comes to growing in confined spaces. This must mean there is more to know about photosynthesis than just Chlorophyll absorption. This LED technology allows us to attain the results of HPS at the same intensity. For the other two contenders, their score is measured as a percentage of that score. Green light certainly seemed like it gave a  boost in the results. Compare: HPS lights vs LED lights . Since I started growing with these lights I have put my m/h hps 1000 and kind k5 xl 1000 into storage. Its really Informative. A 600w HPS light can produce up to 150 to 300 grams in optimal grow environments, which is 0.5 grams per watt or less. NLPIP then compared the streetlights’ power demand and economic costs over a one-mile stretch of roadway. IES publishes UV guidance and joins with IDA on outdoor SSL advice. Some HPS bulbs contain enhanced blue or other small s. pectrum changes, but at the end of the day, an HPS is an HPS. Thanks Dan, your lights are the best. Colorimetric parameters for hps l led grow lights hps vs led grow lights the spectrum how to find led equivalent wall packs hps vs led grow lights the spectrum Hid To Led Conversion Chart 14 TableHow To Find Led Equivalent Wall Packs Replacing HidsHow Many Lumens For A 400watt Metal Halide And What Is The… Read More » Yes, you will see benefits using our light for both veg and flower. So this study did not consider wattage at all, it equalized the output to the same light intensity for each light source and distances: here. A quick review of our search results brings together the top 5 articles and blogs on outdoor lighting. I switched to flower earlier than I usually do and it’s a good thing because they BLEW UP in flower. Let’s face it, this is going to be a hard one to crack, so where do we turn? The Swedish lighting group reports an SEK 16.6 million loss as pandemic prompted factory shutdowns in Italy and the UK. I got two ES 300’s in a 4×4. I purchased the es180’s, 3 of them for my 4×4 tent and I connot believe the growth. The program has a demonstrated history of transforming the market and upgrading the quality, reliability, and energy-efficiency of lighting products by providing objective, third-party information to verify product performance compared to manufacturer claims. Nothing comes close to these lights. In many ways the LRC is grateful for the attention given to this report, because the overarching goal of NLPIP is to provide objective information to those specifiers. These are the key areas for photosynthesis POWER! I hate to gush, but this type of light technology puts color right where we need it. A phosphor spreads light across many colors like a prism. We can’t beat the sun, but when creating light ourselves with electricity, certain colors are better than others. Use the S/P ratio chart to select the S/P ratio for the LED wall pack. No matter how far technology advances, plants remain constant and react to light the same from day to day. if you’re being specific and saying it’s only a purple led then whats the point, might as well grow it with a torch. This research equalized technology by testing all the grow lights at the same intensity of light. That brings us to the part where infrared light becomes incredibly effective. I am limited to an 8′ ceiling and usually control any height issues with netting. That’s right, the amount of photosynthesis jumps by 50%. The two different technologies are entirely different methods of producing light. HLG 650R replaces a 1000W Double Ended HPS and HLG 550 R spec replaces a 1000W Single Ended HPS. adroll_currency = "USD"; Below is the famous “McCree Curve”, the version found in the original scientific paper by Dr. McCree: The White LED seems to fit in the same shape as this curve and “match” it. If you couldn’t tell after reviewing these LED technologies, neither purple nor white was the best for plant growth. You’ve seen the side-by-side grows on YouTube, however, they are often biased or just done wrong. For those who have yet to discover the beauty of the LED, LED bulbs are “Light Emitting Diodes,” where electricity flows through two electrodes ­- an anode and a cathode). Armed with this knowledge we can grow better plants in our own homes using the latest science! Can you figure out what wavelengths were responsible for the growth changes? Meet with Finance / Budget staff as well as Council members during the initial and final phases of the conversion plan proposal process. Hey Simon, this is referencing a scientific study, all light sources were tested in a lab setting for equal PPFD, so wattage was ruled out. This group also holds a belief that blue is for vegetative and red is for flower. However, we can only do this to a point before yields start to diminish. Do plants use only red and blue light? They’re showing a spectrum, and we’re about to see some actual results . The reigning champion of grow lights. This means we rule out the many factors that change from brand to brand. It gets even more confusing since factions for either Led or HPSclaim that the light works best for their cannabis plants. The “yellow glow” was everywhere. May your mind think differently about plants and light after this article! These lights surprised me in every good way. Check out the results below. If you’re interested in learning how to think beyond white grow lights for plants, Here is a graph commonly used by white LED grow light manufacturers, this one is taken from, Are you surprised? As we’ve already said, a lumen is a unit of brightness and it represents a simple and easy way of determining how much light a single bulb is capable of exerting. Some other energy-saving advantages of switching to LED lighting include: We present the results of this study done by a scientific laboratory and used wideband, narrowband, and white LEDs, some with filters to test how plants responded to different % light spectra (blue/yellow/green/red/infrared) which shows us how plants truly respond to colors, which is very exciting. HPS is generally shunned for vegetative growth because of a low amount of blue, so plants can get a bit stretchy. By running a 2000 watt load for 1 hour, 2 kilowatt hours of electricity have been consumed. I hope you learned something. I and my friends are impressed. The Full Spectrum LED and the CMH have similar proportions of Blue, Green and Red to the Sun. NLPIP recently performed a formal evaluation of existing street-lighting technologies to determine the best choice between LEDs and HPS. Now…on to our contenders. As for the Purple Grow lights id love to see the specifics on the led (spectrum of nm for each), every proper grow led should use Royal blues and Deep red’s. HPS vs LED Cost and Efficiency: Initially, LED lighting options for parking lot lights and street lights are going to cost more than HPS lighting. Our Electric Sky LED Grow Lights adopt this new & groundbreaking technology in a special spectrum tuned for ultimate flowering plant performance. The only references to … The report was widely publicized [see links to LEDs Magazine articles under Related Stories at right], but many third-party summaries and interpretations were misleading, so hopefully this article will clarify a few key points. Side by Side Comparison . Example 125w HPS and 75w White LED per m2? With so many conflicting marketing claims, a lot of them must be wrong and only a few right… but who? They seem like they would be the best of all grow lights for growing cannabis – they’re low on energy, low on heat, and also they just look cool! This LED will have the following issues, so it’s best we look for another solution for our red and infrared: So, on to the new technology that is going to start taking over the LED game, the wideband red LED. Pour la culture du cannabis, les lampes HPS ont été le choix de base pour les cultivateurs du monde entier. This makes this showdown a bit more interesting. Comparing Efficiency, output and performance for HLG 650R vs HLG 550 Rspec Commercial LED Grow Lamp. The high-end home automation outfit could give GE Lighting its spiffiest polish since the bygone days of Jeff Goldblum’s dazzlingly cheesy Terry Quattro character. When I stumbled upon the results of what I’m about to show you, I was completely shocked. So everything is dry now and the here are the LED plants. While these LEDs are not rated nor designed for plants, some growers have found that they perform well because they provide a wide spectrum of light, not only red and blue. 7 Myths LED Grow Light Companies Tell You. There has to be something better out there…. These lighting fixtures use many different “LED colors” (aka multi-band) to create a wider range of light, and the spectrum will match as closely as possible the graph of Chlorophyll absorption. You’re about to learn something you’re never going to forget, and your plants will thank you! If you’re completely new to indoor LED grow lights, you might want to check out 7 Myths LED Grow Light Companies Tell You, First of all, it is no question that LEDs are more efficient at creating light than an HPS lamp. This spells some trouble for those of us out there who have already purchased LED systems… up to. The Lighting Energy Alliance at the Lighting Research Center was behind new research findings that suggest uniformity of lighting is more important than light levels for parking lot safety. Turtles hatch to warm LEDs on Alabama’s gulf coast. Below are two graphs from a leading purple grow light manufacturer, Kind LED Grow Lights. Light coverage is perfect. The bag weighs 10 grams so the Platinum LED produced 155 grams or 5.5 ounces. Grow lights are always getting brighter and brighter…. Final Yields LED vs HPS Comparison. It’s dreamy really… Just think of the amazing plant growth you’re going to get. Light in this color (above 700nm) is called “infrared light”. I have 3 es180’s in a 4×4 tent and all I can say is WOW. Do you have an idea of what could be causing the massive efficiency gain? High-Pressure Sodium: Hot, Hot Heat. “Kelvin” (Color Temperature) and “CRI” (Color Accuracy) are two metrics that white LEDs will always abide by. LED ou HPS, c'est un vieux débat, alors plongeons-y et regardons les avantages et inconvénients des deux solutions. White LEDs are created for human eyes. Meanwhile, it withdraws a dividend and puts off its annual meeting until late June with coronavirus about. It has confused the growing community for years, and for good reason! The tomato plant is a fantastic test subject. He recently retired a 600 watt HPS and offered it to me. Otherwise, you risk environmental damage from lead and mercury. Less growing power! How much energy was consumed during the test period and light source? The 600w HPS side produced 175 grams or 6.25 ounces. Sea turtles thrive with amber LED lighting and dark sky advocates rejoice. The HPS ‘Dual Spectrum’ Bulb emits mostly Red and Green with almost no Blue. Bigger leaves, heavier stems, more flower buds = bigger harvest! 3xES300s in a 5×5, two weeks in and have never seen anything like it. Less growing power! The results of the life cycle cost analyses are summarized in the chart below. This means purple LEDs are only, To this day, even after analyzing this particular study for over a year, I can’t get over how spectrum caused, Different colors of light cause different characteristics to come out in plants. Every indoor grower Is looking for that perfect spectrum. With more than 40% reduction in consumption, you’ll be able to experience more long-term savings with LED lighting. In some cases, The McCree Curve as found in – “THE ACTION SPECTRUM, ABSORPTANCE AND QUANTUM YIELD OF PHOTOSYNTHESIS IN CROP PLANTS”, That’s right, the amount of photosynthesis jumps by 50%. adroll_pix_id = "JRXWOCGCWZERXFBFT4FKYW"; We’re looking for light surrounding 700nm. Since HPS won in every category, it scores 100%. Your marketing is compelling. The comparison categories here are based on what I've learned so far about growing with LEDs and dealing with LED companies. You knocked it out of the park. Maybe on the tight and bushy side? So it’s best we avoid older narrowband technology and focus on creating a continuous band of light in the red and infrared range. Our light does come with a dimmer and adjustable straps making it very easy to adjust to your specific grow space and needs. Besides the fast growth rates (knocked about 2 weeks off my flower time), my yields increased by around 20 percent, and the frost… OMG, the frost on my plants is amazing. Thread starter Veghead; Start date May 11, 2016; May 11, 2016 #1 Veghead New Member. Lumen Comparison Chart. Good article either way, i’d be interested to see a test based on the above. But what we haven’t seen is the definitively better growth performance from LED grow lights, even at wattages that are nearly the same. When we’re talking about photobiology, it’s important to work off of percentages and color ratios. LED Street Lights The high power LED street lights LU1 are designed for the street lighting demand and fully meets the special requirements of street lighting. White LEDs are created for human eyes. To meet the collector-road lighting criteria, NLPIP found that when compared to HPS, current LED street lights: • can save a modest amount of energy, and, • usually have a greater life cycle cost, with or without the need for new poles. Manufacturers that use these LEDs often say that they are efficient because they match the “McCree PAR graph” or “fit inside the HPS graph”. Will it stand up to the science of LED? Got wimpy and small plants in veg? UV-C can seem like a germicidal panacea in the coronavirus pandemic, but the IES warns about appropriate use; and the IES and IDA issue outdoor LED lighting guidance. Actually, plants don’t understand “watts” they understand light output (aka, umol/J). When growing a flowering plant, we want them to grow big and strong in the vegetative stage. Ketra supplied lamps and luminaires to The Lodge at Gulf State Park that deliver functional lighting for humans and that don’t interfere with hatchling turtles on the Alabama coast from making it safely to the ocean. Robert Emerson discovered the “Emerson Effect” in 1957. With newer LEDs, you get to have more yields, thanks to a better PAR delivery. In Depth comparison for high efficiency Horticulture Lamps. Overall the benefit of led (besides heat and energy usage) is the individual nanometer or narrow spectrum which can be used to create a perfect grow light as well as full control on the spectrum via controller and dimming if required. Hey, I would like to repeat the question about wattage. How’s that for efficiency? What we need to know is what type of light is actually best for plant growth. Just look at all that color in the 680nm – 720nm range…  Beautiful! Compare: HPS lights vs LED lights. adroll_language = "en_US"; If you’re completely new to indoor LED grow lights, you might want to check out, You’ve seen the side-by-side grows on YouTube, however, they are often, For example, comparing the “GrowBoss 400W LED” vs the “HotDawg DE 1000W HPS” light doesn’t help us understand, HPS bulbs simply come in different wattage sizes. Enjoy the site! Plants need a robust, strong, and large structure to gain momentum for explosive growth in flower. If you’re a data person, check out the results table below: To this day, even after analyzing this particular study for over a year, I can’t get over how spectrum caused such a difference in performance! Here is a graph commonly used by white LED grow light manufacturers, this one is taken from Nextlight LED Grow Lights. In the beginning, all we had was the standard, incandescent light bulb. As is the case with all NLPIP publications, Specifier Reports: Streetlights for Collector Roads was designed to tell a story in an objective way. There is no way around it. Here are the spectrum compositions that were used in the laboratory test. Pingback: Electric Sky LEDs: The Next Generation of Grow Technology? Great question. LED. They are “locked” into certain shapes of the spectrum, so the color options are somewhat limited. Those are some interesting results. Many municipalities are weighing the benefits of both LEDs and high-pressure sodium (HPS) as they consider their street-light options. 5 Barriers to LED Grow Light Domination – HPS vs LED Grow Lights. Now, we might want to add a tiny bit more blue to the spectrum to help with stretching. What this is telling you is that the closer light gets to red (600-700nm) the more effective it it is, which is why red is so good for plant growth. Grow Light Height from Seedlings, Clones, Plants. 32 plants were used for each spectrum, which means this is a very accurate test. This study is not factoring in how efficient each source is at creating light. After a number of fits and starts, GE is finally completely out of the lighting business that was its legacy with Savant Systems acquiring the GE Lighting consumer lamps business unit. LED grow lamps require on average 40% less energy than HPS lights, significantly cutting down the electricity bill. Our GS1 spectrum is patent-pending and proprietary to our brand, but it grows like nothing else on the market, and does what it says it does – bigger and faster growth! If you do a quick search in Google for “LED light burn”, you’ll see horror stories… this is one reason why. If you’re going for LED, at least choose something that has a large amount of green or yellow light. This is merely a demonstration of how much spectrum is important for plant growth! Also recall our earlier discussion on lumen depreciation; LEDs depreciate far less drastically than HPS—so much so that an LED fixture at 85% of its rated life will perform as well as an HPS fixture at 50% of its rated life. Blurple LED manufacturers claim that plants mainly use red and blue light because that is what Chlorophyll A/B pigments absorb. The more lumens a light bulb produces, the brighter it shines. Is the green light in the white LED spectrum going to bog it down? What about the little amount of blue in HPS? If you’re interested in learning how to think beyond white grow lights for plants, see this article. Over the years, advances in technology have brought about innovations in how to light our homes and commercial buildings. The LED street lights recommended by the manufacturer representatives would cost more than twice as much to own and operate as the incumbent technology over the life of the streetlights, primarily because the LED street lights required narrower pole spacings to meet the recommended practice for illuminating collector roads, and the cost of the poles per mile dominated the life cycle costs. I love the results and the low heat. Okay! Do you think the HPS can be dethroned? LEDs will always beat HPS on a light meter…. “Kelvin” (Color Temperature) and “CRI” (Color Accuracy) are two metrics that white LEDs will always abide by. I currently have a veg room and a flower room because of what I understand on the different spectrum’s. Really, the purpose of the test wasn’t about energy at all (we’d care about light efficiency metrics then) it’s all about the spectrum and discovering which creates the biggest growth for plants when placing the intensity at an equal level.
