Low Voltage Halogen Lamp, made from a quartz material. The transmission cut-off wavelength is between 350 and 400 nm. This lamps use doped quartz which is an effective barrier to potentially harmful ultra-violet radiation while maintaining the other high quality properties of standard clear fused quartz. The axial filament types have been specifically developed to satisfy the demand for a wide smooth beam with a good cut-off, from a miniature linear reflector, for the uniform lighting of vertical surfaces. It is suitable for residential and commercial purposes, especially illumination of light sensitive objects in shop windows, galleries, museums.
