1.1 Halogen bulb
The quartz halogen bulb, used as a light source, has higher luminance and colour temperature than
conventional tungsten lamps. The luminance of halogen bulb is approximately four times brighter than the
conventional tungsten lamps.
As long as the lamp voltage is kept constant, the halogen lamp maintains the same level of brightness
and colour temperature regardless of whether it is new or nearing the end of its life span.
1.2 LED module
The LED module is specially designed to be inserted into halogen bulb socket directly converting
halogen illumination to LED illumination. LED is more economical and environmental friendly and no
heat issue with a long life span.
