    • A/C Infinity IONBOARD S22 is the best 100w grow light I have used
Color: White Size: 2x2
A/C Infinity IONBOARD S22 is the best 100w grow light I have used. I have gone through several of the cheaper, under $100, grow lights and they all burnt diodes quickly. As for durability, this is the 4th IONBOARD I have purchased in as many years and they are all still going strong after dozens of grows. They are very easy to set up, fully adjustable brightness, plenty of power so see massive plant growth! When paired with the A/C Infinity controller, you can fully automate the timer, brightness and control the full range if A/C Infinity products, like fans, humidifier, heater etc. You won't be disappointed ... show more

    • 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

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

    • Great when it’s working!

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

    • 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
