Sylvania Coolfit 50mm
low voltage halogen lamps have an aluminized reflector that the heat and the light directed forwards. This makes them very suitable for recessed downlights. Almost all the heat and light is projected through the aluminum reflector to the front of the lamp, so that the armature will remain cooler and therefore safer. Hence the name coolfit. Durable aluminum reflector
for constant light output and color temperature throughout the life of the lamp. Excellent color rendering. Instantly recognizable by the blue cement in the lamp base. The life of the Sylvania Coolfit is 3x longer as standard halogen lamps usually have 1000 or 2000uur. So can all 12V 50mm dichroic reflector lamps replaced. Lifespan: This coolfit bulb Sylvania has an average life of 5000 hours!
