I found an "indoor garden" fixture at a yard sale several years ago that 
takes two 20 watt (2 ft) fluorescent bulbs and two 15 watt incandescent 
bulbs.  That's a more equal proportion of fluorescent and incandescent bulbs 
than Jim said is recommended, but it works beautifully.  The characteristics 
of light from incandescent bulbs varies with wattage and this set-up must 
provide a much larger proportion of red  (light.

The fixture fits perfectly above a plastic tub and I drape a blanket above 
it.  That keeps the cats out and maintains the tub at a nice, warm rooting 
and germinating temperature, even in the cold corner of the room.
