Help with lighting HQI

shepbird07 · 09-27-2007, 02:06 AM

I have a hid lamp ballast. Its a MH-175 watt rated 90-260v
Can I run a 150watt HQI bulb instead of a 175 HQI build?
I know some ballast you can't do this. If I did this would it shorten the life of the bulb?

Thanks,

i would not. the bulb might burst, or at least it would kill the bulb very fast.

No you need the correct wattage ballast to match your bulb

I wouldn't.

Thanks everyone for the help. I called and check and was told the ballast is made too run 150 /175 watt bulbs. That was a new one to me.

wonder if the voltage drops automatically with that ballast when you put a lower wattage bulb on it? Less voltage could mean less wattage
