Great Kit
Written by Mile S. on Feb 16th 2017

Dan was very patient and helpful with all of my questions (new to indoor growing). Package arrived on time, very discrete, and packaged so well I believe it could have been dropped down the stairs and survived nicely. Can't say how well it performs as I just started it up. WEAR SUNGLASSES! It's bright. The kit is very well thought out, and color coded connections make electrical assembly such that it is very unlikely to make a mistake. Too easy. I chose 1-1/2" x 1/8" aluminum for my frame. (probably overkill). Hardest part of assembly was making sure the measurements were spot on to align with the heatsinks. I recommend a drillpress. My space is small (2' x 3.5'), and the heat from the lights only raised the temp from 68 degrees to 72 degrees. So, they are very cool. Heatsinks are just warm to the touch. Quality product.

Great deal for DYI
Written by Closet Smoker on Jan 24th 2017

This is a great deal for someone not afraid to make a frame. All prewired connections are covered in heat shrink for safety. Color coded wire connections on the COBs make it easy to know that it is wired correctly. Comes with a power cord to plug into wall, plenty of connecting wire length provided. I made a unboxing and assembly video on YouTube, look for my channel under Closet Smoker. I did have one minor issue. The knob for the rheostat was missing in the kit, but Dan responded quickly and sent me one. Thank You!

Written by AJ on Jan 17th 2017

This is a really nice light kit. The wiring, connectors, potentiometer, heat sinks all are good quality. Cree 3590s are top notch. Dan is a real class act, just a pleasure to talk The light produced (3500K) reminds me of a sunny summer afternoon, but the cob/heat sinks stay quite cool. I say"cool!"

Dan gave excellent service,very easy to deal with No hype,no bs these lights just work. Forget the panels that blow up halfway thru flower(good luck w/warranty) will deal with Timber again.

Excellent kit
Written by Josh on Nov 7th 2016

This kit is great. I started off by purchasing 2 of them for my tent. I've been using the 8 light led setup for about 3 1/2 weeks now and I can honestly say I'm thinking about adding four more, I like them so much

200 watt kit
Written by yooper420 on Oct 29th 2016

First email was responded to very promptly by Dan, and all others, for that matter. Customer service gets 5 stars. Kit came very well packed in a USPS box, very discreet. Bought 3/4 X 3/4 X 1/8 thick angle aluminum, as suggested, to build the frame from. Think it turned out to be an excellent decision to buy and build this light. In a few months we will see how well it works, after my first harvest that is. This light will be combined with 2 other LED`s, until I can replace them. Plan is to use 4 of these 200 watt LED`s to light my garden. Thank You Dan and Timber Grow Lights for an outstanding product.

Best kit and even better customer service.

Not only is this kit insanely high high quality, from shink tube to built in fuses and materials in general. It really is as user friendly as it gets. Plug and play. Dan is a super helpful and great dude. I would recommend this kit and this company to anybody in the market for COB's. Hands down A++++

happy plants!

Great package, saves many hours of research and diy work. Not much more expensive than sourcing parts individually, and great customer service. Seriously, I spent ten's of hours researching and ended up coming right back to Timber. I'm happy I did, are so are my plants!
