can i use a 150 watt metal halide bulb with a 175 watt ballast?
Or maybe a 100? The bulb on the security light behind my house burned out. After looking inside the ballast is rated to 175 watts, but I have a couple 150′s and a 100 laying around from my work lights. Is it impossible, possible, or possible but dangerous? I like having visibility back there, but some times it’s so bright it bothers me at night.
Its ok to use a smaller wattage lamp than ballast,but not the other way round,if you do it will burn out ballast.
