This grow light is great but has one major flaw. In the photos you could see the outlet that connects light to light. But the connection is not US and the plug keeps falling out. If the company could send an adapter for this it would be perfect. I had to contact ecogrowhawaii.com about it because I wanted to connect this light to others. I asked them to try to contact the vendor for support but ecogrowhawaii.com could not reach them. ecogrowhawaii.com is sending me a new light and I imagine that I’m going to have the same problem since the ecogrowhawaii.com representative cannot see the type of connection that I need to make. I would go buy one but I don’t even know what type of connection it needs to stay in the light. Otherwise, I have to say there is no light as good as this one on the market for this price point. It has a built-in fan and adjustable light. The instructions are clear. The cables they send with this light are the best. I cannot see how people have ever complained about these lights breaking because the packing is so good. If you want to put this light on a surge suppressor or timer it would probably be best on a surge suppressor because the cable is very thick which is a very good thing to prevent fires, but I just can’t see it working that well with the timer. This unit burns cool but is extremely bright. An additional fan in the room would still be a good idea. I am growing herbs and I put it 16 inches above the head of the top of the herb and turn it at about 40% to 60% and leave it on about 12-14 hours a day. My herbs are on the west facing window and the light does not burn the plants but moisture level needs to be checked frequently and plants misted because they do dry out a bit more quickly. If you think that the light doesn’t work I would check my soil because it needs a soil mixed with perlite and moss or a low density potting mix NOT POTTING SOIl- but POTTING MIX! If you are the vendor of these lights please send me connectors that will work so I can link them together but ecogrowhawaii.com is sending me a replacement this week and wants me to return the other one to you.
