Abstract
A compact fluorescent lamp includes an inverted compact fluorescent light source housed within an outer envelope. Locating the first and second ends of the coiled CFL source positions the electrodes within a substantially spherical outer envelope at a location remotely spaced from the ballast compartment. In this manner, only small diameter first and second lead wires that mechanically and electrically engage the electrodes pass through small dimensioned passages in a separation member in the outer envelope cavity. This substantially reduces the thermal stress on the components.
