Roleadro 2000W LED Full Spectrum Grow Lights for Indoor Plants, Greenhouse, Seedlings, 2000W, 2000W

I have found these lights to be both economical to purchase and operate and quite reliable. We use a lot of herbs in our cooking. I have been able to maintain my indoor herb garden as well as start my heirloom tomatoes from seed. Some of my herbs have even flowered. I plan to try my hand at growing tomatoes and lettuce indoors over the winter, so I will likely order another light.After reading a few reviews, I wanted to address some misunderstandings regarding LED technology. First, lumens mean little when talking about LED. To put it simply, lumens measure how we see light, not how plants perceive and use it. For plants, it is all about the intensity of the usable wavelengths of light given out by the source. While some lights, like the Marshydro, may seem arguably brighter, they actually provide fewer of the usable wavelengths plants can use (6 vs 9 bands; although they claim 10 because they count the hi/low of each band, unlike other manufacturers). Nonetheless, they are also good lights, btw.As for burned out leds; more than likely people are looking at the IR LEDs, which do not shine very brightly and can appear to be broken.When it comes to wattage, it's pretty simple. Most companys use the wattage of the led times the number used. This is misleading as most do not drive the leds more than 50% of their rated power. So 300w LED = about 150 actual watts.Finally, the troll comment regarding cheap chinese lights...well ALL of these lights are sourced from China. And most of the time, the only difference between 300w light for $100 and one for $600 is the brand name, plus a few unnecessary bells and whistles. Google is your friend here. Don't believe the manufacturer's hype.UPDATE: Still great lights; Amazon delivery...not so much...I made the huge mistake of ordering a second light for Sunday delivery. The package tracking said it was delivered, but no one ever showed up. I know because I was outside at the time USPS claimed it was delivered. To make a long story short, I had to spend my own time and energy running around trying to track the order down. I called Amazon and the CS rep did what she could, but the bottom line was that I could either wait 3 days for a refund or wait 3 days to see if USPS could find the package. I foolishly chose the latter. It will be 3 days today and not a word from anyone. Now I will have to wait another 3 days to get my money back. I doubt I will reorder, which is too bad since Galaxyhydro was very responsive to the issue. It isn't their fault, but frankly the time and effort I spent on this far exceeds the cost of the light. As a almost day one customer of Amazon, I have to say that they are really dropping the ball lately. This is the second package I have had to track down. I signed up for prime for a reason and running around looking for my order was not it. So, now I have to find another venue to buy my Xmas gifts as I would like my loved ones to get their gifts in the same year I buy them. Amazon delivery gets zero stars from me.

I’ve purchased a LOT of grow lights over the years, as someone who loves their collection of tropical house plants, but who also has to struggle with Pennsylvania winters, and this one is by far the best one I own. It’s BRIGHT, and will make your house look like a UFO if you don’t have some serious blackout shades, but it gets the job done. For the Seinfeld fans out there, my husband jokingly refers to it as the Kenny Rodgers Roasters light. It’s the only thing that has kept my plants in my basement greenhouse thriving through each freezing winter. I love this thing so much, and my only regret is not buying three instead of one, because they’ve been unavailable on Amazon for like a year or so now. Pics are from when we still had it upstairs. One inside and one from outside across the street.

This is the third different led panel I've purchased for experimental purposes. Initially it gets 4 stars because nothing can get 5 until proven through an entire grow cycle. So far so good though...UPDATE: Completed an entire cycle with this light now. What I've learned is that distance to canopy is critical, as with most lights including LEDs, but even more so with this one. It will fry seedlings if hung too closely, I've found the 18"-24" spec to be a good starting point but it took some experimentation to get it right. As another reviewer pointed out, you'll get crazy results like nonexistent nutrient burn/issues and etc if hung too close and at minimum you'll stunt your plants growth. Worst case of course is that if left unchecked u will most definitely kill your babies. Start at 24" height, go from there is my advice for what it's worth...Also, the output is VERY red. Visually speaking, very red, spectrally it's red dominant so expect much better performance in a flowering cycle. I ended up using it as supplemental lighting to 2 mars hydro reflector 144's and the results were quite good. Resin production using this combo was awesome and among the best I've seen but I'll attribute that more to the mars units than this.Overall I would not use this again as primary lighting for my needs. It's ok, just not good enough for my personal needs...I tend to gravitate towards the 3W led panel array designs, I feel it's still the sweet spot between electrical and spectral performance. Anyway, it's solidly built and those fans do move some air! Consequently, expect some noise. Not too bad but for its size it's definitely on the noisy side, for me not a big issue though. Louder than most desk sized fans on highest speed put it that way...I measured around 262W of actual usage, for a 600w design I feel that this is a pretty good number. Driving an individual 3W led at these design levels should ensure a decent service life so I think that thus far this is a well designed grow light...I've been running mine now for about a week, nearly 24 hours starting seedlings. At the 5" - 6" heights I'm using I'm measuring between 2900-3000 umol, panel-centered sensor, which is outstanding intensity by any standard. So yes I agree with many others who say that it's quite bright! Of course, these values will drop drastically the further the distance and I expect that I won't be using it much more than 24" from canopy at any given time anyway. When I have time or get to the point in the grow cycle when I can measure PAR values at greater distances I will update with more data...Seedlings seem to be responding well to it so far. I'm measuring about 80 degrees F, 5" beneath the fixture, on center. It makes some heat as expected but very manageable...Overall it's about as what I'd expect from this type of design. If it performs well in longer term trials I would definitely consider purchasing more. Again, I will try to update as things progress. Thanks for reading, hope it helped.
