Some time ago, I bought a set of quartz halogen lights for my aquarium. About a week later, one of the 5 bulbs burned out. I figured it was just a bad bulb, so i just bought a new bulb replacement. but since then, three more have burned out also. I checked the voltage, which seemed to be about 6-8VAC. the bulbs are rated for 12V 5W. WHY should they keep burning out like this???
