250hps voltage?

[BagseedSamurai]

I was gifted a 250 watt HPS light for my next grow, only problem is that my friend said it was configured to run on a 277v current. Is there any way to convert it to household 120v?

(or toss me a link where this is explained?)

It really just depends on how the ballast is made. If it's a multitapped ballast (usually have 4 wires coming off the ballast marked with 120v, 207v, 240v, & 277v) all you have to do is disconnect the 277v wire and attach the 120v wire in that wirenut. If the light came from a larger commercial building, it very well might not be multitapped - in which case it's going to be better used as a boat anchor unless you are one of the few with 3 phase power in your house.

Your 1 volt short on one of those voltages lol

lol....I was calculating in voltage drop for him

Should be 208v, but if you can't use the 277v then the 208v will never get used either.
