    • Great light for price
Color: White Size: 3x3
Exceptional quality as always from AC Infinity. Easy to put together and easy to use for any crop. Dimmable knob for brightness makes it function exceptionally easy

    • I am impressed
Color: White Size: 2x2
It is the most efficient light to date for me, so I have great hopes it will last a long time. I am impressed with how cool it is, apparently 20k lumens at first blush. Great color rendering. Dimmer 80,60,40,and 20% barely any heat at 60% and under. Comfortable to drink and hold coffee cup warmth on high. 2000 lux at 5'8' while a 320w chm is 3000 lux. It would be a more flexible, more uses, if it could dim to an additional 5% and 1%. At 20% it is too bright to put on a timer to wake up with and use in the bedroom. I need 80k lumens to work with, so it is too dim to take to work. But it is a good house chore light. It does come with one plastic led protector, but needs several and option to buy replacement, since the leds are exposed, making the light unsuited for harsh conditions. Hopefully it lasts longer than the mere months of usage that all other 100w+lights have gotten before dying. ... show more

    • Life spand is short. And it's not a cheap light.
Color: White Size: 4x4
Review Image by Alex C.
I bought this lamp 2 years ago. Amazon as my witness. I used this lamp only to flower in a 3x3. It's an awesome lamp!!!! But it's damaged. It started flickering yesterday and today it didn't turn on. So with that been said, think about it, 400$ for 2 years and used 8 months ago year. I hate to say it, but I'm go8ng to experiment with another brand for my light. My last review update, I called AC infinity for the warranty of the lamp. And in lest than a week these guys sent me a new lamp. With this been said, You can't go wrong qith AC infinity!!! ... show more

    • Best products around
Color: White Size: 2x2
Gabriel, and the team at AC Infinity are the best, they actually answer there phones quickly, and take the time to listen to your concerns, they have some of the best and first products out there, and always coming up with new products, you can’t go wrong with any of their products

    • It's ac Infinity, it's great!
Color: White Size: 2x2
As with all my other ac Infinity products this light is well made. If you've ever handled the cheap LED lights before and then you get your hands on this you can just tell it's made with high quality material. The description says they are LM301 B diodes but the box it comes it says LM301 H. I don't know if thats a typo but if not that's awsome. This light would take care of a 2x2 space well but I'm using it along with a S24 in a 2x4 and it's killing it. The light gets a bit hot to the touch but I'm not have heat issues in the tent. I definitely recommend this light for a 2x2 area or adding it in to supplement other lights in a lager space. ... show more

    • Great when it’s working!
Color: White Size: 4x4
Review Image by Matthew Z
It's a great light. It just HAS to have a fan blowing on the black part on top, otherwise there’s a good chance you’ll be calling to get a warranty replacement. AC Infiniti is great about that I will say. I had to replace two of them already so I’m not messing around. It’s a drastic level of difference that a fan makes. ... show more

    • Bad light.
Color: White Size: 3x3
Love everything about ac affinity really good product. I have bought a lot of stuff from them but my light went out and did not know still had warranty until after the warranty so I lost all my grow because had no light. I only got half the hours out of it. It would of been nice to get a replacement out of it since only got half the life out of it. I have bought 3 lights and tons of other stuff from them.But I still love there products! ... show more

    • You wont need a tent heater.... Bring your sunglasses
Color: White Size: 4x4
These 4x4 lights are very warm. Which raised the temperature in my tent by 10 degrees. However, I guess I dont have to buy a tent heater since its at 76 degrees now, instead of 66 like it was..... Awesome! They are very bright, very very bright (running on 80 percent). So bright, my plants are mad now because they were used to less bright lights. So, I'm hoping they perk back up asap. Hopefully these lights last a long, long time for the price, but im nervous since many of the reviews claim a 9-12 month life span before failure due to overheating.. If this is the case, hopefully AC Infinity don't mind giving me new lights every 9 months for the rest of my life. Could present a problem though, since I dont really have any backup lights laying around..... Fingers crossed. As long as they last at least 20 years, I would say they are great. 😆 ... show more
