hi
just being into fish house and as its dropping dark noticed that the UV bulb is flashing so went to turn it off by following lead from ballast to the plug and the ballast is HOT in fact too hot to handle. so question is the bulb causing over heating of the ballast or vice versa.
the ballast has always being warm to the touch but not hot like this.
which to change or both if ballast suggestions where to purchase
