Most exit signs at school have been converted with those garbage LED retrofits. But a few scattered units still burn their pre-retrofit incandescent lamps! This one uses 15W 145V T6.5 bulbs.
Ah, my school only has 2 incandescent exit signs some of the LED's at my school seem to have random burnout spots. Im from Canada. How many people here are from Canada anyways?
UPDATE 09/11/2013: The lamps inside this exit sign are now both burnt out. I doubt it'll be relamped with incandescents...
