Hi, You can also make one from a GE G4S11 incadescent UV lamp in series with a 40 W standard bulb that acts as a ballest. Shouldn't cost more than $4.00. Do not stare into the UV Bulb. Can be bought at most places that sell freezers. I've the same bulb since the 2708 came out, for those that rember that far back. Bye for now
