Everything is outstanding about this light, took me a couple runs to learn how to use it. But if ur growing indoors in a tent then this light gets a lil warm on full blast. However 75% is plenty of light and usually only use this during flower and might turn it up for the last couple weeks of flower, so .. just a heads up.. 25% is great for seeds and veg.. i will turn it up to 50% around 6th week of veg. Also depending on stage, higher humidity, consistent and frequent watering will help with heat.. hope this helps, works for me! Im also an organic farmer..😁😎

Best light I have ever used

It’s Awsome 4 different settings summer time right now it’s on 280 because of the heat but 2 of these lights in a 4 by 8 by 61/2 tent it’s plenty for veg and flower I’m plenty satisfied thank you growace 👍👍👍

Advance Spectrum 680W Sun Series Model E 6-Bar Full Spectrum LED Grow Light

They run pretty hot I’m gunna need to get AC system as well

A couple of weeks and I see a huge improvement!!!

The Light is more then expected, im very impressed so far. I still havent used it on Full blast but the lowest setting and adjustability is outstanding. The quality is superior and look farward to many harvests. If it produces what i think is capable then i will purchase 4 or 5 more of these for sure.. thNx again, happy harvestz!

Myself and family recently purchased lighting. They are amazing, a game changer from what I see.. but with directions those who don't understand electrical vue would start ordering converters and turns to a mess.
Me, I plugged it in and the 600W of greatness was released and I am a happy customer.. we shall see how season goes. I'll upgrade as production is satisfied

Honestly so far so good the lights are awesome. I'm impressed with my purchase so far only downside was I didn't receive a trellis with my order

have two of these they handle my growing needs for 6x7 sea of green

Shipping was fast. Light came as described and works best. Had originally ordered a different light that ended up not being available anywhere and they were kind enough to send this one as a replacement. Great company to sure business with!

I have been using my light for several weeks now and I love how much cooler the light is compared to my 1000 W Bulbs! It apparently is working better than my old lights.

It's hard to rate my new light because I just started using it, but I'm very satisfied with my overall experience and I would recommend grow ace. com.

The leds exceeded my expectations.I am very pleased with this product. Works like a champ

Im on my 3rd cycle with light, and it has very much impressed me every time. I use to have a Spectrum King and this light blows it out of the water.

Great light, with awesome results! Always stays cool and pulls even less wattage than advertised. Checked mine with a Watt meter and found it only pulling 290 watts!!! Super efficient amazing product!

This light will grow your plants like a HID but with better coverage. If you want to go led this is the type of light you want to get. Full spectrum white light,with long bars to give you perfect canopy coverage.Add a far red light at 735 to 740nm and turn it on at the last 15 minuets of the bloom cycle each day for faster budding and over all finishing quicker. Use UVA and UVB, HO T5 lights at the last 2 weeks of flowering for resin production like never before,slowly work these UV lights in ,as they are strong,5 mins a day working upto 1 hour a day.If the plants start to burn your using to much uv light. UVA can be used all the time,,its UVB that brings out the rezzzz,and is very very strong spectrum of light....be careful when using it.

I was a bit apprehensive about trying this light. I've previously used the Kind LED and the California light works solar flare. Really glad I gave it a shot, this thing ROCKS. I'm now on my 3rd harvest and the results are unbelievable. Believe the hype of the 7 specific wavelenghts, the broad spectrum covers it all. My plants are fuller, aren't stretching for light and the fruits are insane. I grew 2 plants under this light and got 1 pound per plant.... insane! Love my Advance Spectrum, I'm switching all might lights in the next harvest.

There's a lot I like about this LED fixture. It looks nice, is relatively inexpensive to run, and there's no more excess heat from running a conventional bulb and ballast for 12-hours a day. That said, the downside for me is that plants that previously took 8-weeks to fully flower now seem to be taking closer to nine weeks. I've been at this hobby for quite some time and have repeatedly read that the only thing that will influence flowering time is Co2 levels. The only other possibility I can think of is that my plants may have benefited from the extra heat of an HPS bulb and ballast? The room temperature is regulated though and stays between 66-80 degrees. Please remember to wear good eye protection with these lights as there is a UV emitting diode in each bay good for plants, not good for eyes.

In the 2wks they have been on after transplant, the result is impressive . Veging big time with strong stems and stalks . These lights do make big difference, very good.

Full spectrum ..How Kool is that ?

Well i have 2 S540 that are going on 3 years old. It was time to upgrade with another Awesome Grow light.. I've been growing with three lights for 3 years they are the Bomb simply outperform in every aspect from Size, Dense flower. You will not be disappointed with how these lights perform on Veg's thru Incredible Flower.

Was using an MH and HPS bulb before this. This panel blew my previous results out of the water. I would highly recommend this to anyone.

I wanted to get something that i could use over and over and get some good results. Well no worries with this light.. from Veg to some awesome looking flower these lights have performed Outstanding.. Now it's only my first cycle but am impressed by the quality of the light..

I've been growing for many years using MH andHPS but this light is incredible. No more having to move plants or change lights. The heat is half of what it used to be. Its about time someone designed a better way to grow ""anything"" indoors. Not enough spaces to give enough stars

I bought this light. 10 out of ten!!! Grew 4 plants that produced 15 ounces. One of the best lights ever. I ended up buying 6 more

My plants are straight up huge get some of this ish

This is my first time hand selecting key pieces for my grow room. For the longest time, i have been researching which other type of light is best for the the work I do. These lights produce a strong series of wavelengths which combined provides huge amounts of light coverage for half of the 5 x 10 tent that I have. The design and build of the lights does surpass any other lighting system that I have used. Very strong, and durable frame. Excited to see results.

Super impressive light. Worked wonders for my plants! Will definitely be purchasing more of my growing equipment from you guys!
