These lights are awesome. I ordered the lights and received them 2 days later. I would say that is great service. Thank you.

Love these lights!!!

Great quality, very happy with my light so far, easy to setup, waterproof quick connections, fused plug, and potentiometer! Amazed at the price being so low with all that pre wired for you, lower than the competition by a lot. I will definitely be doing business with these guys in the future when i upgrade/addon to existing lighting - another great thing about these kits is its fully expandable, just addon to a existing kit or make a new one. Timber and RainDan have been awesome, they will help you in any way you need and answer any questions you have regarding your specific setup, TIMBER ROCKS!!!

I only recieved 3 reflectors with my 5 cob kit.

Excellent product, communication, and value!

The kit is awesome. Saved me a lot of time. And just look at the components. They just use the best stuff and don't cut corners. The workmanship in all the connectors was to notch. But the real value is the way these guys work with you to make sure you get what you're after. Free shipping right here in the US. I bought four of these kits and I can't think of one thing they could have done better.

Awesome light

I had always wanted to build one of these, but I wasn't comfortable enough with electronics to build one. This kit made it completely possible, and even fun! I waited a month to write this review to see some results and my plants are LOVING it. I have never seen results like this from an led! Blurple lights are a thing of the past :D

Really nice!

These guys did a really nice job in setting everything up for a successful install. Everything was well packaged, tidy, and labeled. I was glad that I was able to order a custom built frame from them too. They were quick to get back to me with answers to my questions, and were very thorough. The light works great. It's cool, silent, and has a pleasing color. I'm planning on working with them more in the future.

great value

After researching various sourcing options for cbx3590 parts I was very pleased to find this diy package as I am both lazy and cheap. My order was delivered in very good packaging with each assembled lamp in its own little box. The shipping box was generic which I appreciate. If I need additional lighting in the future timbergrow will be my first stop.
