My setup is similar to seadrive's. I use a clamping bullet reflector and a 15watt bulb. Both can be purchased at any hardware store. I have taped some neutral density film over my reflector to cut down on some light and slow exposures to the 15-30 second range. If you can find a 7watt bulb to fit the reflector, that might be better. It all depends on how dense your negs are, how fast your paper is, and how high you set the bulb above the paper. My bulb is about 3 feet above the paper. The bulb is plugged into a timer. I use a second reflector with a 120w grow light for Azo.
