I almost bought the wrong light. It turns out the up side to LED in the outdoors is that they emit a different spectrum than bugs see so I found a solar powered flourescent that will work much better. Unless you use UV LEDs they wont attract bugs. There is a UV LED solar bug zapper you could hang over the water if you wanted to feed your fish cooked bugs. Here is the link to what I think will be my first purchase in this area:
