SYLVANIA 54305 Tru-Aim MR16 – 20W 12V 10° Narrow Spot Halogen Lamp (GU5.3 Base, ANSI ESX, Covered Dichroic, Axial Filament, 3000K)

The SYLVANIA 54305 (20MR16/SP10/C(ESX)-12V) is a low-wattage Tru-Aim series halogen MR16 reflector bulb with a precise 10° narrow spot beam and advanced dichroic/IR technology. The infrared reflective coating reduces heat in the light beam by up to 66% (most heat emitted rearward), paired with a UV-filter axial filament capsule and covered constant-color reflector for safe, brilliant accent lighting—perfect for heat-sensitive applications in retail showcases, museums, jewelry displays, galleries, track lighting, and focused architectural highlights. ANSI ESX code, made in Germany.
