  • Ac infinity
Color: Red Size: 4x4
This is my 2nd ac infinity light. Great light I wish I had switched years ago. Last month I bought the halo t-24. Just can’t beat an ac infinity product well built, high quality materials. Definitely can see the difference between this and the Chinese garbage out there.

  • AC FOR LIFE
Color: White Size: 2x2
Excited to write this review. Why? I started growing indoors this year. I settled for other set ups but learned my lesson quickly. As far as quality,price,and reliability they are on. Bought grow lights, fans, a humidifier all quality. Prices are fair. Not to mention most products plug in to a device that automates the entire grow. I recommend AC 100% THANKS GUYS! ... show more

  • 4x4 is a huge upgrade to my grow tent
Color: Red Size: 4x4
My six year old "purple" light finally died on me about 8 weeks into the veg stage, so I decided go with something more modern and efficient. One note - there is an error under the "specs" on the amazon product page at the time of writing this. The 4x4 model draws 400 watts, not 100. This thing is a beautiful, heavy duty design. Everything was packed very well, the included documentation easy to follow, and their beautifully illustrated grow guide is a nice addition for relative newbies. It is packed with all sorts of info you need for a successful grow. The light output and spread / coverage is excellent in my 4' x 4' x 80" tent, and the included hardware makes for an easy setup and height adjustment. It does put out a fair amount of heat, but the AC Infinity exhaust fan (not pictured) takes care of the heat just fine. I'm excited to get so much more light output with a much more efficient instrument like this, and I can't wait to see how my next grows go from start-to-finish with all the new AC Infinity gear. I liked this light so much I immediately ordered their exhaust fan / filter combo, a clip fan, and the 69 pro controller. Can't wait to get everything set up and automated today. Wish I'd just gone for the all-in-one tent kit from the beginning! The energy savings alone from the more efficient LEDs, and being able to schedule everything more specifically, should pay off in no time. Will definitely be adding their humidifier and heat mat for the next cycle. Highly recommend! ... show more

  • great lights!
Color: Red Size: 2x4
These LED lights are very well made and have great samsung LED bulbs that I bought to replace an old LED fixture I had that was killing some of my plants. After using these I'm sure the growth will be great! Hoping that the bulbs last for a long time, as I fully expect them to! I have another 4x4 LED kit from AC Infinity that is working really well and producing some great plants, so I'm super happy with the way those lights are already working for me. Overall, very happy with product! Can't really think of a flaw. ... 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

  • 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
