I have a friend who moved into a house with a "fiber optic" pool light unit that wasn't working when he moved in. He went to the pool store and they gave him a replacement bulb -- it's a GE 24V 250W halogen lamp, i think its the same as this one:
The one thing odd i noticed is that the open circuit voltage of the transformer is only 20V.
Possibilities? I'm thinking the open circuit voltage for a 24V light would be way above 24v(?)... Is it possible it's really a 12V system? Any other ideas? what else would cause the bulb to pop? These bulbs are pricey (~ $20) so I don't want to just keep popping them!
[halogen bulbs run better hot -- something about the tungsten atoms redepositing on the filament with high heat]Thanks!
