Works great. Measures on LUX meter and FC meter. I also tested with UV curing nail glue; and it cured. My plants are shade plants so I only have on 2 hours at peak daylight. UV is mostly under 400nm (most meters pick up above 380nm but also don’t always measure UVA) reptile heat bulbs for example are a different nm reading. ... show more

    • Another quality product from AC Infinity
Color: Black Size: 11-Inch, 4-Bar UV
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. ... show more
