Lights worth getting?

Do these look like something worth messing with? I assume that they only would be if the voltage can be switched. And I know that only the ballasts and mogul sockets would be worth having off of them.

High Pressure Sodium Vapor light fixtures, includes ballast, 250 Watt lamp & reflector.

These fixtures operate on 277 volts

Have 33 (HPS) units avaiable... also some MH fixtures.

$25 each or best offer for the entire lot.........perfect warehouse lighting.

I'm not an electrician, but I guess if you have 220v in your house they would work. 25 bucks is cheap enough.

There's something about Ohm's Law that messes with this. I=V/R. I'm too blazed to worry about it right now, but I think it's half the light in twice the time.

it's half the volts and twice the amp.

100 watt bulb woulld use .909 amps. at 110 volts

or

100 watt bulb would use .455 amps at 220 volts

so my last post was f'ed up the watts stay the same. I buzzed that should be a no brainer. You can make the bulb brighter. Daaa sorry I corrected the last post, thanks Solstice07

Anyone here besides me know how to use one?
