AC InfinityIONBEAM U4, Targeted Spectrum UV LED Grow Light Bars 11”, 4-Bar Lighting Kit with 365nm and 395nm Diodes, Digital Dimming Schedule Controller, for Indoor Plants, Grow Tents, Greenhouses

these lights come with enough extension cords for a 4x4 tent. and they work good. great for side/supplemental lights. the small control panel is nice also. I just wish they were a bit cheaper priced. thanks!

I got these for a small grow space that I built to use as supplemental lighting and they are amazing. The quality of all their products is seriously second to none. I have several of their fans as well and I couldn't happier. Even the packaging is top notch. It really is a quality brand.The controller that comes with it is easy to use and program. The wires for the lights are plenty long enough for my application. The magnets on the back of the lights could be a little stronger in my opinion but that isn't a deal breaker and not enough of an issue to take any stars off. The intensity of the lights are really high too. Definitely advise wearing glasses of some kind if you have the lights bright as they will hurt your eyes if you look in their direction and could potentially cause damage.They don't appear to get really hot when in use and the price of these lights is very affordable for what they are. Would absolutely recommend these lights for anyone looking to add UV to your grow space.

The magnetic backings are almost unusable, but the lighting works well.

These lights are fa-reaking fantastic!! They are really small and compact but bright,made with quality materials that feel good in your hand, magnetic backing, secured connections over the connecting cords, digital controller that connects to other AC Infinity products, also included is a thorough manual and a small hemp growers guide/ AC Infinity catalog. They really put a lot of thought into their product, I'm super impressed!

Love it.

They definitely add a UV spectrum to your grow room, only need to run em a few hours a day, and only in late flower. I recommend not to run em all day long the plants definitely don't like that. But they do like a few hours a day

This light is powerful. I used it for 2 week 30 minutes a day on level 6 and had massive results.

I bought these in March of 2024 and chips are already dying less than a year in. I really don’t know if they improved my yields or quality. I’ve been having great runs since I put them in but that could also be explained by my skills improving.They did work nicely until the chips started burning out. Integration with the UIS controller is nice. The magnetic mounting allows you to put them pretty much anywhere.Once these burn out all the way, I’ll do a couple runs without them before deciding whether to replace them or not.
