65 WATT MR 16 TYPE FPB HALOGEN LIGHT BULB - 36 DEGREE BEAM SPREAD - LONG LIFE 6,000 HOURS Starlite MR16 halogen lamps utilize a titanium reflector coating to ensure consistent color throughout the life of the lamp - eliminating color shift. A quartz envelope and pure tungsten result in durability and longer life. The regeneration cycle continuously restores the filament, creating a 6 times longer burning life and clear crisp white light. Nickel end pins resist heat and provide positive electrical contact. A unique backing prevents light loss out the rear of the lamp and disperses heat more efficiently - resulting in 100% of the light beam projecting forward.
