1 Special halogen lamps Optical GX5.3 specular 50 mm GY5.3 faceted 50 mm GX5.3 faceted 50 mm GZ6.35 specular 50 mm Features Quartz halogen lamps for optical applications with an integral reflector which serves as an efficient mirror condenser system.their glass reflectors have a dichroic coating which reflects the light forward. But radiates about 75% of the generated heat backwards, keeping temperatures within safe limits. The halogen burner is precisely aligned using an optical system so that no re-alignment is necessary when relamping. They offer negligible light output depreciation and high efficacy. Low voltage halogen lamps should not be dimmed by more than 10% of their rated voltage since this will result in a reduction in life. Standard tungsten filament lamps (with no halogen filling), can be dimmed to zero volts, resulting in virtually endless life. However if low voltage tungsten halogen lamps are dimmed by more than 10%, the lamp will be operating at a too low temperature and the free halogens in the gas fill, will attack the cooler parts of the tungsten filament i.e. where enters the quartz or glass envelope. The wire at that point will then be eroded and eventually will fail. So if dimmed by 10% or more, low voltage tungsten halogen lamps will not have an extended life but are unlikely even to reach their rated life. Applications 8/16 mm film projection. Slide projection. Enlargers. Minilabs / Colour printers. Overhead projection. Medical equipment. Solar simulation. Measuring equipment. Fiber optical applications.
