Can I use a compact fluorescent light bulb in an enclosed light fixture?
Compact fluorescent light bulbs may generally be used in enclosed fixtures as long as the enclosed fixture is not recessed. Totally enclosed recessed fixtures (for example, a ceiling can light with a cover over the bulb) create temperatures that are too high to allow the use of a compact fluorescent bulb. Many CFLs can be used outdoors in an enclosed fixture. Check the lamp or package to make sure it is approved for outdoor use, and verify the lowest operating temperature for the area where the product is being used. If the lamp or package does not state it can be used outdoors, then it is not approved for outdoor use even in an enclosed fixture.
