Uv security light?

[dunl]

Are these safe to us as a light to help make corals glow? I found a small one specifically for checking for counterfeit bills. 115 volts 60 hz .20 amps

Thanks

Thanks. Can anyone, including yourself, confirm this for sure?

UV sterilizers some people use in their tanks do this on a constant basis.

To use it as a sterilizer yes, to light the tank, no. They will harm your tank more than you think, for one there's a reason why they tell you not to stare directly at a UV light and/or blacklight (which is what those security lights are), the effect would be the same with fishes.

Okay, that makes sense, but don't MH light put out at least some UV light? It's about an 8" long bulb, very small....I figured it might be a nice moonlight. Especially when I have seen some freshwater people do this.
