The overall color temperature of FSM's full spectrum is controlled at 3000-3300K, which increases the radiant energy of red light at 660nm wavelength in white light. It provides a beautiful working environment and a more realistic color reproduction degree at a CRI level of 85.

Growers Choice ROI-E680 LED Grow Light Reviews

Just got the 680s
will see if they live up to what all are saying about them. But it is like the sun.very bright. we like all we see with them.

exemplary customer service
I left a previous review at 1 star that I'd like to amend. Hydrobuilder and the manufacturer were outstanding in replacing this light. I think one being bad was just an fluke, I'd use their product going forward.

I have the 680 for two days now it’s so bright
I have the 680 for two days now it’s so bright How do I change the colors that I don’t know

Amazingly lowered the heat and electric bill
I purchased (2) of these last May and I really like them. Unfortunately, 1 of the light bars failed, however, that was probably a good thing, because, I was able to see how they handle the warranty. They shipped me a replacement immediately and told me to use the box to return the defective one, which allowed me to continue to use the one that I had until I received the new one. 7/8 of the capacity is better than reinstalling my old HPS light. They also included a return shipping label. While that is the kind of service that I expect, I was very pleased that they delivered in a time that few companies do. I am purchasing 2 more!

Great buy definitely what they advertise.
Been through a bunch of different lights that say they are the one you will need, but never enough in flower . But the ROI-E680 does exactly what they say they will and more. Gonna be adding another one soon.

High quality next gen lighting
I was a lil taken back by the price of these fixtures until I did the math. Temperature: lower cooling costs, plant temperatures, humidity levels etc.
All of these metrics are reduced equating a healthier growing environment and less environmental manipulation needed, less fans, dehumidifiers, air conditioning etc. = $$$$$$ Saved. Yield: I hear these claims about 2.5 lbs per fixture, I have yet to attain this. What We are seeing is a constant 2.5 lbs plus per 1000 watts which is very respectable. We've only been using these fixtures for months not years, but so far so good. The build quality is excellent and with a three year warranty I feel pretty confident in there durability. If you can afford them, they will pay you back and then some !!!!!!

Works great
Been using it for 6 months very happy

First LED I Liked
I've tried 6 types of LED lamps over 10 years now and been let down everytime. If your flower takes a nose dive in the market it's hard to compete. Every LED I've bought to date ended up in a veg room and most broke within 4 years. I thought they'd be solid in a closet but no way on professional growing.

Anyway this light matched our HPS output. We have 4000 sq ft of indoor garden. This light matched 1000 W DE output in terms of yield, clearly stayed cooler, and I got the same % as the same cultivars grown across the room under HPS. I felt this took it up to a another level because I saw about a .75% increase in terpene output and more blue and purple hues that everyone loves. Felt the LED was tastier, largely due to less heat stress on tops. I highly recommend this light.

The real test to me is will this last 9 to 10 years? I can't tell you it's going to last forever yet but after 2 crops it's the first LED I've owned that out performed my HPS.

Difficult set up
These Lights are very bright and energy efficient . This light has produced better quality flowers than hops. Very minimal AC needed in a two light set up. With this being said it was a very difficult set-up if using with the master controller. Not all rj 9-14 wires are compatible. I had to wait days for working wires to ship from the company . Instructions were very limited and the website is the worst to navigate through.

Great light
Growth was much more aggressive when I switched from purple to these

F@cking awesome
This light is like grabbing the sun from the sky and putting it in your tent! Unbelievably bright and my girls look like they are basking on a Caribbean coast. The best money I have spent on my hobby yet!

Very even and intense light.
These led lights are where the future is. This one is currently averaging 2.5 #s per light and is only 680 watts!! A hps, mh, or dual end lamp doesnt spread the light intensity over your whole canopy like this. Save on your cooling too, they run about 80°.

work great
they work as advertised and are worth the money.I am a disabled vet and they gave me a discount for that so i will be a loyal customer from now on..

Love the open design
The new open style of this LED is great for maximizing coverage and dispersing heat. My buddy has 2 of the new Gavita LED grow lights, and they do amazing. This light so far is just as good. Plants are loving it so far!

With the controllability for the growers choice controller, you can adjust the intensity and timing and includes different modes.

This LED is WELL WORTH THE MONEY! Will be buying more!
