A HID bulb (HPS, MH, MV) will draw as much power as it has available to it, in the case of a power overload it could blow, and if you payed attention in chemistry, you should know that sodium exposed to moisture will explode violently, possibly blinding, or killing you. Spend the $35.00 and get a 250W bulb.
