Starting off with a "1200W" LED off amazon going to the 4VL, you realize the power difference with the 4VL when you're bending over in the tent and feel the intense heat beaming off the COB LEDs, watch your hair! Killer gains with growth. Where light is everything, this product comes through. Also really awesome customer service!

Pure Awesomeness!!

I am a home grower growing my medication for close to 7 years now. I started out with 1000w HID and HPS lights. Satisfied with results with plants growth and yields but controlling heat and energy costs are not very practical. I switched to LED about 2.5 years ago, very satisfied with energy costs but not with plant growth or yields. I have tried several different LED brands which I will not name but these lights have received awards and acclaim. I do research thoroughly before deciding on purchases and I DO NOT BUY CHEAP CHINESE MADE AMAZON SOLD LIGHTS!!!!! After researching for better lights because I was disappointed in the my results, I came across Timber grow lights. After sound research and corresponding with Timber sales associates I decided on the 4VL based on my grow space. I have been tremendously impressed to say the least so far with the results that I have gotten from these lights. My plants love them and respond in a way that I have not gotten from previous 2 brands of LED and with HID and HPS. I am currently still in veg stage so haven't gotten to the flower stage as of yet, so not able to comment on yields but will update once that stage is reached. I will definitely consider purchasing these lights or other products from Timber Grow again. I am very pleased so far.

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.
