Ushio MR16 Relekto Halogen lamps (2 inch diameter) feature an aluminized reflector coating to dramatically reduce the heat energy to the back of the lamp. Ideally suited for recessed ceiling fixtures and landscape bullet fixtures where thermal damage to sockets and fixture components pose a problem. Much like a PAR lamp, the aluminized coating reduces the back spill of light through the rear of the reflector. With glass front cover.
