I bought a set of four a year ago to augment an ill-advised LED fixture for a 3'x4' garden ... the extra 200W put things over the top! Dan was immediately responsive in getting me a part that had been 'misplaced'. I just purchased at 2nd bank of four as part of a new 2'x4' enclosed tent garden. The continuously variable output is a major plus when full output isn't needed for veg. I've found running about 3/4 power (150W) at 22" above seedlings produces vigorous growth...the second bank will be used at flower time for the full 400W. At full power, the MW power supply does get quite warm, but not hot. I run an 80mm muffin fan blowing along the PS, at which point it runs cold. The lamps themselves essentially run cold at 35W each, and warm at full output (50W each). The entire package is of the highest quality! I recommend this to anyone needing COBs in this output range.

I bought this kit for adding supplemental lighting to my greenhouse - Dan was very helpful in providing longer wires to help with that, and even sending extra wire after the fact, gratis. Works great!
Speedy Delivery. Well Packaged. Bright^awesome!
I'm very impressed with the overall experience with Timber Grow Lights. This kit is great. Very bright at 100%. Definitely buying another set. Thanks Dan.
