Can CFL bulbs be used in recessed can-style light fixtures?
Yes. For more light output and cooler operation, only reflector style (R-lamp) bulbs should be used in recessed can fixtures. Challenges in converting recessed lighting fixtures to CFLs, include: • Size: CFLs are sometimes longer than the bulb they’re intended to replace. To accommodate the extra length, remove the bulb and look inside the fixture for a way to adjust the position of the base (usually a wingnut and a slot). • Beam spread: CFL reflector bulbs may have a wider light pattern than standard reflector bulbs. CFLs are best for wide flood applications and not as a replacement for spot lights. • Shorter life: Due to the position of CFLs in recessed fixtures, the ballast runs hotter. This may shorten the life of the CFL bulb and/or reduce the amount of light output over time. However, the average CFL will still last longer than standard reflector bulbs. A Department of Energy testing program is helping to identify products that perform best under these conditions. If your CFL fai
