hands Down best bang for your buck. I did a side by side comparison with a grow light double the price, the canopy coverage and umol were incredibly better.

I'm impressed. Worth every penny. Penetration is deep. Growth is vigorous Put on your sunglasses for these babies.

This is the fourth kit I've purchased from Timber and once again I'm impressed. In the past I built my own fixtures but this time decided to let them build it. No regrets. Looks great and performs even better. My favorite lights for growing!

Works really well. Don’t forget sunglasses because this sucker is bright!

Starting my tomatoes, brussel sprouts, and peppers with it. It doubles as the heat source as well. Very bright. Well made and looks good too. I like it a lot. The dimmer is nice as well so I don't cook the seedlings.

I shipped internationally to Canada, took its time getting here but is well worth the wait. American assembly with what appears to be Japanese parts, a match made in heaven. Kicks off good heat when cranked up but compared to the Mars Reflector 480W I had before its quite literally night and day. Night and day as in I can see through the cracks in my tents zipper from the outsife when I crank it up that's how powerful this baby is. Made me buy a whole new tent just to fix that for flower. Great light so far, if it holds up I'll be buying another smaller timber light once I reach flower on this grow

This is by far one of the best lights ive owned. My plants love the light coming out of this light fixture. Ill most likely be getting another soon.

These guys build a great light. When I got my light from timber I immediately noticed the quality, so glad I decided to go with them. Fast shipping, excellent customer service and a quality light that impresses. My plants love this light. If your looking for LED lighting look no further this is your light!

Very pleased with my decision to purchase the 4VS for a 3x3 grow tent. The light arrived in a timely manner in very secure packaging and is very well built with great components! It puts out a LOT of light and I am eager to see the next harvest. Buy this light! Well worth the money! When you buy quality, you only cry once!

Amazing!! I ordered 2 of these in 3000k with a center mounted chibi in the 1750k. Top notch lights no doubt!!

Wow I was blown away coming from a blurple Chinese light. It's perfect for my 3x4. It's well built. It's like staring into the sun and its growing strong plants. I wish I had ppfd readings with lenses off at different heights and different levels of the potentiometer, like 25%,50%,75%,100% at 20, 28, 36 and 42 inch hanging heights.

I started off with blurple lighting from another company and after using these timbers its a night and day difference. Higher yield and denser nugs, never turning back

Love this light very nice people are very friendly and helpful hope to get another one soon!

Top notch light, top notch customer service. I was considering an equivalent cob setup from another company since I'm on a tight budget right now. I'm so glad I spent a little more with Timber. It's well worth the customer service, support and warranty that they provide. Every time I open up my 3x3 tent, I love seeing this beauty. I think I would be kicking myself if I had to look at the other company's "cheaper looking" setup every day. Don't hesitate if you were in my budget situation....you will be glad you decided to spend a few extra dollars.

Have almost a year using these lights. They procude the same quantity as a 600w HPS but the quality is definitely better! With low heat, energy efficient and rock solid parts/construction, these are the end all lights for indoor growing. Get the 3500K and changing lights will be a thing of the past! Can't recommend more!!!

Wanted to say thank you. This was used for my second grow. Very satisfied. Used this in 3 x 3 tent with two plants under scrog. Also used a true 75 watt red led dorm grow light with this and got just under lb. Top notch light.

This beaut just came in today. Very impressive detail on these fixtures. Great packaging; very easy to hook up solo. Excited to see how this light will perform in my 36x36” grow space. Great customer service and response time. Quick shipping.

High quality light build. Plants seem to love the intensity. How ever mine did not come with splayed heat sinks. I think it would have been more efficient at cooling with them.

This light is great and covers a very good area very evenly. Very bright with a nicely installed dimmer that is easy to use. Timber has outperformed all of the former panel LED's I have owned. I highly recommend.

It is a great light in my opinion. I have it over a 3x3 space. With 9 plants flowering under it only let them get 3' or 4' tall but top so gives alot of top. Very even light coverage with the bonus of 2 dimmer switches. Had it for only a few months but has done way better than any other light i have had in the tent. So worth the money, just wish the different light choices where available when I got mine. My only issue is the power cords are very short 3' max.

5 stars Great light, great customer service, Highly recommended for non-DIY types like myself who are looking for best lights available at a reasonable price
