Can you figure out the special ability that infrared light (700nm) has when it is combined with red light (680nm)? Coronavirus wipes out Q1 profits at Fagerhult. The results of the life cycle cost analyses are summarized in the chart below. The LEDs have become more efficient. A phosphor spreads light across many colors like a prism. The comparison categories here are based on what I've learned so far about growing with LEDs and dealing with LED companies. The reigning champion of grow lights. Enjoy the site! NLPIP analyzed the pole spacing needed for the streetlights to meet a national roadway lighting standard for collector roads, ANSI/IESNA RP-8. This way we can pick up the full benefit of the plant photosystems (I & II) that reside at 680nm and 700nm. Our Electric Sky LED Grow Lights adopt this new & groundbreaking technology in a special spectrum tuned for ultimate flowering plant performance. 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. Those are always fun to read! It’s way cool…. Are plants going to grow weak and lanky in veg? Before we breakdown the contenders, let’s talk about the current reigning champion. I have 3 es180’s in a 4×4 tent and all I can say is WOW. The Swedish lighting group reports an SEK 16.6 million loss as pandemic prompted factory shutdowns in Italy and the UK. Less growing power! Thank you for the test and interesting article! 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. And as far as performance goes, I think you will agree that there was a clear winner. If you’ve been growing for a while, I’m sure you’ll recognize these familiar faces. PNNL scientists investigate the potential of a new NEMA ANSI standard to address performance variations that may be found across 0-10V dimming controls for outdoor LED luminaires. You knocked it out of the park. Hey, I would like to repeat the question about wattage. Tony and his team tested the SolarSystem 1100 against the 1000 watt DE Gavita lights by swapping 20 of the HPS lights for 20 LEDs. 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. There has to be something better out there…. Other days it looks like HPS is outdated after the next bulb swap. Bulb breakage and bulb replacement costs have not been factored into this comparison chart. Will plants grow lanky with a weak structure and small leaves?V, Maybe plants really don’t use green or yellow light…. LED wins this bout. Pay close attention to lumens, since this number indicates the brightness, or light output, of the bulb. This means purple LEDs are only half as efficient and white LEDs lag by 25%. You are almost ready to shop! If you’re interested in learning how to think beyond white grow lights for plants, see this article. Okay, so we really want infrared in our spectrum. Green light certainly seemed like it gave a boost in the results. Manufacturers that use these LEDs often say that they are efficient because they match the “McCree PAR graph” or “fit inside the HPS graph”. How come there’s no spectrograph representing your full Spectrum? Notice how that as blue light increased, the smaller the leaves became. LED Outdoor Area Lighting Fact Sheet. Remember, all of the lights were scientifically adjusted in a laboratory setting to be the same intensity in the same environment. 4. Luminis luminaires with amber LEDs in Gulf Shores, AL ensure that turtle hatchlings safely make it to the ocean, and the post-top fixtures are dark-sky-friendly for humans. Generic comparison between HPS lights and LED lights. In fact, you should be waiting until your plant becomes a certain size and strength before flowering, so if your growth spectrum isn’t helping you achieve that goal, think of the time you are wasting! If you do a quick search in Google for “LED light burn”, you’ll see horror stories… this is one reason why. You’ve seen the side-by-side grows on YouTube, however, they are often biased or just done wrong. Grow lights are always getting brighter and brighter…. Incandescent bulbs and CFL bulbs are more easily broken than LEDs, which increases their cost of use. So everything is dry now and the here are the LED plants. All rights reserved. We are going to tackle the question which light bulb type reigns supreme? How much energy was consumed during the test period and light source? Keep at it… as technology and prices are always changing. Less growing power! Since HPS won in every category, it scores 100%. See the graph above? White LEDs are increasingly popular and are becoming ubiquitous in our society. 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. I and my friends are impressed. © 2020 Endeavor Business Media, LLC. adroll_current_page = "other"; I hope you learned something. The HPS vs LED grow light matchup is a clash of the titans. (MAGAZINE). Does the graph above even match the HPS spectrum? Way to go Dan. Required fields are marked *. So what is … 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. LEDs will always beat HPS on a light meter…. The green “line” is a white LED, the rainbow outline is the spectrum of a High-Pressure Sodium bulb. For instance, the LED grow lights are 48% more efficient than the HPS. White LEDs are created for human eyes. The growth rates are ridiculous! Don’t get me wrong, comparisons are valuable, but they are quickly outdated as new technology is introduced. HLG 650R replaces a 1000W Double Ended HPS and HLG 550 R spec replaces a 1000W Single Ended HPS. We will be presenting the results of an exciting scientific study that puts grow lights on a level playing field. The UK-based Lighting Industry Association surveyed its members, reporting 89% of companies are still operating at some level, while the Mexican government shutters a Cooper Lighting plant. Some days it seems like LEDs are just… a passing and expensive fad. I have a surprise for you… this scientific study also tested new, emerging LED technology. Below are two graphs from a leading purple grow light manufacturer, A phosphor spreads light across many colors like a prism. However, in order to most closely follow the typical specifier selection process, those were the street lights NLPIP purchased and evaluated. There are multiple layers of biological light receptors within a plant – they are complicated, living beings that sense for light, Did you think that blue light would have assisted vegetative growth? Check out the results below. There are a lot of factors to consider: temperature, distance, humidity, water, nutrients, strain, grower experience…. Many municipalities are weighing the benefits of both LEDs and high-pressure sodium (HPS) as they consider their street-light options. This spells some trouble for those of us out there who have already purchased LED systems… up to. Let’s explore why LEDs are gaining on HPS fixtures! Since HPS won in every category, it scores 100%. So — the key thing to note is that this graph shows the effectiveness of a photon once absorbed in a plant, but it is showing the result of how a plant responds to one color at a time. For the other two contenders, their score is measured as a percentage of that score. This means purple LEDs are only half as efficient and white LEDs lag by 25%. We can now focus on how efficient the spectrum of the light is to achieve growth. Customer for life!!! That’s right, the amount of photosynthesis jumps by 50%. Example 125w HPS and 75w White LED per m2? Notice how the HLG 300L Rspec has more relative intensity in the yellow, orange, red area and a little less in the blue. Sea turtles thrive with amber LED lighting and dark sky advocates rejoice. LED ou HPS, c'est un vieux débat, alors plongeons-y et regardons les avantages et inconvénients des deux solutions. This is the reason our product focuses on a wide spectrum for plants, which is what this article is about, and this product has been tested over and over by growers showing fantastic results in quantity and quality. Thanks Dan, your lights are the best. Maybe on the tight and bushy side? This also means that more light from LED is needed to achieve the same results as HPS. If you couldn’t tell after reviewing these LED technologies, neither purple nor white was the best for plant growth. Is the red and blue spectrum optimized for Chlorophyll absorption going to pull ahead? Well, if you’ve read 7 Myths LED Grow Light Companies Tell You, it’s clear that the older “narrowband” LEDs is not very efficient at creating infrared light. Let’s face it, this is going to be a hard one to crack, so where do we turn? White LEDs will always try to maximize green and yellow light, because those are the colors that appear brightest to human eyes. Robert Emerson discovered the “Emerson Effect” in 1957. All skepticisms were put to rest as the weeks passed. Light in this color (above 700nm) is called “infrared light”. I have never seen growth like this. “Kelvin” (Color Temperature) and “CRI” (Color Accuracy) are two metrics that white LEDs will always abide by. Meanwhile, it withdraws a dividend and puts off its annual meeting until late June with coronavirus about. Thanks for asking! He recently retired a 600 watt HPS and offered it to me. How will it do in vegetative growth? Their discoveries, together, unlock secrets we can use to maximize growth in our gardens with artificial light. LEDs come in all sizes and colors: blue, red, purple, white, and every manufwhiteacturer claims they have created the “perfect spectrum”. Two men made breakthrough discoveries in plant science. Plants with many big leaves and thick stems give us the power and structure needed for the flowering stage to achieve massive yields. LED. The Lighting Research Center’s National Lighting Product Information Program (NLPIP) formally performed an “apples-to-apples” evaluation of existing street-lighting technologies as detailed in its September 2010 publication. To emulate the streetlight selection process used by typical specifiers, NLPIP purchased and analyzed eight LED streetlights that were recommended by manufacturer representatives as equivalent to an incumbent technology, namely a 150W HPS streetlight with a Type III distribution. The tomato plant is a fantastic test subject. With newer LEDs, you get to have more yields, thanks to a better PAR delivery. In my honest opinion, these are the best lights on the market. Instead of 1+1 = 2… It’s 1+1 = 3. I purchased the es180’s, 3 of them for my 4×4 tent and I connot believe the growth. Also, be aware that manufacturer representatives may recommend street lights that are not equal in performance. Do you think the HPS can be dethroned? What you’ll discover is that colors and their combinations significantly affect how plants grow. 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. 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. Use the S/P ratio chart to select the S/P ratio for the LED wall pack. 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. 5 Barriers to LED Grow Light Domination – HPS vs LED Grow Lights. The HPS ‘Dual Spectrum’ Bulb emits mostly Red and Green with almost no Blue. So, I installed it and did a grow with it. Thanks for sharing. In Depth comparison for high efficiency Horticulture Lamps. IES publishes UV guidance and joins with IDA on outdoor SSL advice. Notice how that as blue l. ight increased, the smaller the leaves became. HPS lights have been associated with high yields for a long time. That brings us to the part where infrared light becomes incredibly effective. Will it stand up to the science of LED? I damn near grew myself right out of the tent! I switched to flower earlier than I usually do and it’s a good thing because they BLEW UP in flower. Nice, big frosty buds and plenty of weight. If you’re going for LED, at least choose something that has a large amount of green or yellow light. If we compare the mean visible luminaire lumens of your existing HID luminaire and the possible LED equivalent, we will likely find that the LED, even at half the wattage of the HID, will provide far more light than necessary. 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. A recent addendum to the original report examined LED street lights that could match the pole spacing provided by incumbent 150W HPS street lights. We can’t beat the sun, but when creating light ourselves with electricity, certain colors are better than others. Below are two graphs from a leading purple grow light manufacturer, Kind LED Grow Lights. Both technologies are very efficient. Before making the conclusion which is betterLED vs HPSgrow lights, it is important to explore deeper into factors like growth stages, room to grow, efficiency and ease of use … However, we can only do this to a point before yields start to diminish. HPS to LED Conversions – “Lessons Learned” 1. horticulturelightinggroup.com Not here or on the HLG 550 R Spec product page. Now, we might want to add a tiny bit more blue to the spectrum to help with stretching. 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. 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? 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. What do you think about HPS + LED?
