What about halogen lights (efficiency, specta)?

Yesterday at our local DIY warehouse, I saw a portable (tripod mount)
500W halogen light for only $50; same model with two 500W lamps was
only $70. They looked to be well sealed, and are designed for outside use;
would they be suitable for plants? A cheaper solution than halide?
