I want to use some screw-in compact fluorescent lamps in your model Rxx downlight. Is that possible?
Yes. However, there are two important points to keep in mind when planning to do this. First, will the lamp properly fit within the housing? Your screw-in CFL lamp may extend beyond the lip of the housing, which will cause an unpleasant look. Second, some trims are designed around specific lamp types. If you use a “cone” style trim that should have a reflector style lamp, if you use a “spiral” type CFL then much of the light output will not be distributed properly. Whenever you are considering using a screw-in lamp in place of an incandescent in any downlight, it is best to check with the manufacturer for compatibility recommendations.
