Gohyo 18 LED Black Light | FAQs
Would this one light cover a classroom that is about 29’x29’?
Possibly? I used it to light up an area of my backyard . My daughter & her friends were sleeping out on her trampoline and it gave off a good bit of light.
Is this safe or waterproof to use in a fish tank?
No. This item is not designed to work underwater. Also, after owning this for a while now, I can tell you that the plastic/glass lenses over the lights are turning black, due to being burned. That's not good.
Are the lights replaceable for when the burn out?
no, it can't, but you can contact the gohyo brand to get new free one within 18 Monthes becasue of the 18 Month Replacement Warranty. We will reply you within 12 hours.
