Lot of people use this light. There's data out there, I just don't have my own. "telegram" on Instagram turned me onto this light a couple years ago. I've had a few. Gave some away. Lost one. Ect ect. Also back then I didn't have a par meter, and my tank was a disaster, so it didn't even matter. I forgot how good these look.
