Bests & Worsts Reviews from Amazon

If you've grown both indoors and out, you know there's nothing like the sun. Plants can become small trees outside. HPS lighting has been king indoors though, offering high luminosity and a wide spectrum. But HPS is inefficient, costly, and not practical for small grow areas. Traditional LED panels offer targeted spectrum (blue & red), but they've not been able to match HPS yields. Large diode COB LED solutions from Cree and others offer a natural spectrum and wide spectrum nice yields; but they're expensive, even from a DIY standpoint. The Roleadro 2nd Gen LED light features 5w diodes all tuned to 3000K. The result is a wide spectrum light. Please see the attached spectrum analysis from Roleadro. Sparkling clean and well packed, the unit shows nicely. Build quality is impressive, solid but not unnecessarily heavy like Mars II. This 2nd gen light has a finned heatsink, quality fans and electrical connections, and most important, quality diodes and lenses. I've tested many LED units.. I've seen cloudy, horrible lenses, and lenses that burn or discolor within a few weeks use. I have several Roleadro UFO LEDS and can say I've never had issues; they look and perform perfectly. Roleadro uses quality lenses (please see pics). And because they use a mix of 90 and 120 degree lenses, the lighting footprint is spectacular. These units are great size, power, and price to run multiple units. I'd consider actual wall power draw when determining how many units you can run. For example I can run 500w of lighting in a 3 x 3 tent and maintain 78F temps just fine. I can safely run two "600w" panels for awesome coverage. Two panels spaced appropriately offer better coverage. I can't speak on results as of yet but I will update. From someone who won't settle for poor quality, I can say that I'm honestly impressed with these lights. Edit: Another reviewer commented on working with the included hanging hardware. Included are four metal cables and clips, and one D-ring which serves as the single hanging point. I have 2 and 3 link chain pieces on hand that I use with yo-yo hangers, works like a charm. Home Depot sells bulk chain. Ask for four pieces of two links and use as pictured for stable two-point hanging. Adjust height quickly and keep light level.
