Fire risk?

Umm,,

Would using a plastic light fitting like this:

with a bulb such as this E14 LED:

be asking for trouble? I'm sure I could find a metal light, for similar bulb, but I was thinking these rigged on a pole across the tank may work. Might have to get some safety line so they don't 'unclamp', and risk falling into the water!?!

I didn't pay attention in science lessons, obviously!

I doubt the LED would produce anywhere near as much heat as the halogen so you should be fine.
And screw it to the wall, no risk then
