I bought these from Manards here in Iowa. It didn’t have much information other than full spectrum with plant friendly blues and reds. I’m wondering if anyone has any experience with these and any advice for maximum effectiveness.

I believe the brand is Stonepoint LED and it just says “LED Clamp-on Grow Light”

The Cacti I have under them seem to be doing well. I currently run it on a timer for 12hrs a day since the window in that bathroom on casts very bright indirect light for about 11 hrs.

New to grow lights and want to make them useful for the growth of these cacti.

Any advice is welcome!
