Looks like a high pressure sodium to me. I've gotten one for very cheap, around that price. Its just not as good, PAR wise, as more expensive ones.

but it still will work?

you need more than just a bulb, you would need a ballast for it to function and you could do alot better with a higher wattage light say a 150 or 250 or possibly larger depending on your grow space.

yea i know all that stuff, i just wanted to make sure i wasnt mistaking this for a Low pressure sodium bulb, they have that same bulb in a 250 just not where i was looking. Thanks

You STILL need a ballast.
