Can a CFL be used in an enclosed fixture?
When using a CFL outdoors it should be placed in an enclosed fixture unless otherwise stated on the packaging. When using a CFL indoors, some can be installed in an enclosed fixture while others will have markings on the plastic base specifying that it is not to be used in enclosed fixtures. Some manufacturers do not recommend using them in totally enclosed recessed fixture. Please be sure to read the manufacturer’s instructions on the packaging.
