Abstract
An illumination device comprising a housing fixture, a light source, and an active heat transfer device is provided. The housing fixture includes a base adapted to be receivable in a light fixture receptacle configured to receive a gas-discharge lamp. The light source emits light with a color rendering index higher than a respective color rendering index of at least a type of gas-discharge lamp. The active heat transfer device is physically coupled to the light source and mounted to the housing fixture. The active heat transfer device receives power from a power supply to remove thermal energy from the light source.
