Interior LED replacement bulb used in bi-pin halogen fixtures. Lasts 60 times longer than the G4 it replaces, and is 339% more energy efficient (draws 246 milliamps). Patent pending state of the art copper heat dissipation apparatus helps the unit stay cool, thus increasing life expectancy and lumen output (205 LMS, compared to 100 LMS of typical halogen bulb). This product produces a warm natural light - 4000 kelvin. The product is FCC approved and will not interfere with radio/analog signals.
