Abstract
A compact fluorescent lamp (CFL) including an insulating barrier between heat sources and heat sensitive components. The heat sensitive barrier is in the form of an insulative layer of cement applied between the heat generating components of the CFL and one or more heat sensitive components of the CFL. The cement can also fix or secure various components within the lamp thereby eliminating the need for some or all of the support structure of a conventional CFL.
