Is it just me, or does the math on that light not make sense? 20W total rated LED power but a 32W linear + FET driver? Are the LEDs rated on UV output not electrical input, and the difference in power is all lost as heat or visible light or something?
Also, I have no idea if they're on Lemmy but the owner of that website/store is very active on reddit, you could probably reach out there with questions.
Voyager is showing me all four. They're mixed in with the text in a fashion similar to how the page is displayed in a browser.
