Abstract
A lamp is described. The lamp includes a housing made at least partially from an electrically and thermally conductive material. The lamp also includes a primary light source positioned within the housing such that the housing dissipates heat generated by the primary light source. The primary light source configured to emit light in a first direction relative to the housing. The lamp also includes at least one indicator light source positioned relative to the housing to emit light in a second direction relative to the housing, the second direction being substantially opposite the first direction. The lamp also includes a capacitive proximity sensor electrically connected to the housing that triggers illumination of the at least one indicator light source if a user's hand approaches the housing.
