Light about to blow???

[bob`_your_dog]

Hey, I recently found my brothers old UVB light 30 w 90cm and ballast, I changed it for a smaller 25 w 85cm (sun-glo), the guy at my local fish shop said it will work and even tested it. After running all day yesterday and today i noticed the ballast is extremly hot and the plastic appears to have almost melted. Now it could be the fact that the ballast was under a pillow didn't help the heat prob. but I've tried to keep it in a cooler place but she still seams very hot.

Is this normal?

Sorry i also forgot to add, i have an air stone under neath it wich seem to create a constant steam of tiny bubbles some of which pop and land on the tube. Will these little drops of water damage the tube?

Why is it that unles a topic is about some expensive filter or what ever that people never get a response?

Maybe because no-one knows the answer
or no-one understands the question

you shoudl really have a sheet of glaww or a condensaion tray between the water and lights to stop water contact as this may cause water staines on the tube and flourescent tubes need to me keep fairly clean.
