These fixtures are absolutely everything I expected and more in terms of quality build, the yield they produce and the customer service at the other end of the phone. I'm a single woman who wasn't born a lighting expert, but after extensive research, I found Dan. He was immensely helpful explaining cob technology and after we discussed the specifications of my grow area and my expectations from the fixtures, he guided me directly to the right fixture for me. I began collecting fixtures slowly, ordering one, then another and then three more. I have never had an issue with any of the fixtures and I know if a problem arises, Dan will walk me through it. The design lends itself to being very customizable and I expect I'll be using these fixtures perpetually for a very long time to come. Thank you, Dan, for all you've done for my grows!

Communication was excellent! Receive the light in the estimated time frame and was well packaged. This light is extremely bright and very professionally put together. I have to admit this light is flawless to be a DIY light set up. Thanks Timber!!

Received the light a few days ago, and wow this thing puts out a ton of light and the plants love it. Packaging was excellent, everything was bubble wrapped, and then bubble wrapped again not to mention the cobs themselves were covered in hard plastic to protect the lights. The light itself is very sturdy, and very bright. It does get a bit on the warm side so I would recommend that if you do buy one of these get a couple small clip fans to blow across the heat sinks, that seemed to help quite a bit as far as Temps go. I'll definitely be picking up a couple more of these in the near future to fill out the grow and veg rooms.

Good light, build quality is on point. Only had a chance to run it for a couple of days but has met my expectations so far.
