This light works Very well. Word if advise. Start up high and then lower a little every day to get plants acclimated to the light intensity. Worjs awsome and packs on sum nice tight nugs!! I also have a 800 watt cob from Roleadro that also works Very well. Have it alone in a 2x2x5 box and its effectively flowering a nice scrog. Much better than expexted. I also have an older 270watt ufo from roleadro as well. And works fairly well but not as well as the other 2. If your thinking about getting either this 800 watt reflector series or the 800 w cob . Just go ahead and order because they work Great and are very Cheaply priced. So far after about 6 months of use all 3 are still working great. So dont hesitate at least on the 2 mentioned. They dont make the ufo anymore. Excellent fairly priced lights and fast add shipping!I used two of these 190 watt (1000Watt rating) models in a 3x3ft tent. While the performance of the lights at the far edges of the tent was mediocre, it worked well for the majority of the tent.... as you can see.You have to hang the lights about 8 inches above canopy during LATE flower.Roleadro reached out to me via email and has said they will issue me a refund. I think this is honorable. Make sure you observe the light for awhile before committing to it's use and I believe it will be fine. I have other products from them and they work great!The plastic housing around each light has begun cracking and this is after only 2 months of use with it only being on 8 hrs a day. The light outputs just fine but it is very irritating that the cheap plastic is warping and breaking. WTF. I will be reaching out to the company to see if this is just a lemon.Very happy with my purchase. I've purchased from this company before, i've noticed that they've really slimmed down the model without taking away from the light output. For one thing, its about 3 times lighter than the older models, but it seems as a tradeoff they use less chips. The chips must be higher output however, as they produce light just as bright as the older model. The 800 watt model will cover about a 3 feet wide 3 feet long 2 feet tall area very well.I've been using it for 2 months now, and the plants are going fast. The cooling fans are very quiet, but they don't move too much air. I'd prefer something that didn't have fans at all to save the power.I've bought many sub 100 dollar lights over the years, this one is definitely better than any of those. Right out of the box you can see its construction is sturdy. It has 2 large fans that keep it very cool. It's very bright. My plant's love them already. And my favorite quality? It uses only 184 watts for a very bright light. Your plant's will be very happy as well as your electric bill. ?I like the fact that the light make my plants grow very good nice quality itemVery happy with the performance of this light. We've had a cold spring, and my garden starters have had to remain indoors a week more than expected and counting! This light has provided enough light for them to get by without getting leggy from too little light. Very happy with its performance. Will definitely buy a 3rd if my plants outgrow the space my original 2 can't cover.
