Hello Dryst.
Halogen lights are useless. They have the wrong wavelength, put out a ton of heat, and suck electicity like a Tribble! ; )

Home Depot does carry HPS lights but they are the little 70w security lights.

The 27w you saw was probably an incandescent p[lant light, also one step up from useless.

They do carry both compact and tube flourescents, both of which should have a place in your grow room.

Compacts (CFLs) are excellent for small seedlings. Cram as many as you can above the seedling tray.

Tubes are nice, I find, for the late seedling stage, when they have 3 sets of adult leaves, until they are ready to go under HID. Keep the fixture on chains, and raise it as the plants grow, to 2 inches above the plants.

One cool white and one aquarium tube per fixture works for me. 2- 2tube fixtures side by side is even better.
