UV lamp and LED

Curtis

Colleagues, my friend scared me today - he asked why I need a UV diode in the sea? It will burn everything out... But it's not quartz, it's just color, right? The water should absorb the radiation, even if it comes from an LED, right? I ordered one piece (3W) for backlighting, and it will be controlled by a controller, as I think it will give off too much pink. Now I'm wondering - if there's a risk, should I switch to something else? What does everyone think/know?

Well, just read the forum without offense. UV comes in types A, B, and C based on the hardness of the radiation, that's one. Two, even the hardest radiation doesn't penetrate more than 1.5 to 2 cm in water... So the conclusion is, why do you need it????

I'm not sure how much UV penetrates in water, but it definitely causes beautiful bioluminescence in many corals. I've seen it myself. I have 8 UV lights in my maxspect. 403nm. Although the Chinese call them True Violet.

It depends on the wavelength. The shorter it is, the less it penetrates. Ultra Violet (UV) has a wavelength of over 400 nm, which is not even Class A, but even milder. It does not have a bactericidal effect and penetrates water more effectively, so I don't see anything alarming.
