Xenon filled Incandescent Lamps


Incandescent and Xenon Technology

We pioneered the miniaturization of Xenon lamps for use in flashlights. At UK we strive to make lights which produce the maximum brightness, with minimum size, and most efficient use of energy. For years technology limited our selection of light sources to incandescent lamps. We found that off-the-shelf lamps were never bright enough and produced light which was often too yellow. The only solution was to work with selected lamp manufacturers to produce custom lamps to meet our specifications which burned whiter and more efficiently.

Incandescent lamp design for flashlights always gets down to three major parameters, color temperature, power, lamp life. These must be adjusted for the needs of the application. Unfortunately they are all linked together. When one is pushed to the limits the others may suffer.

Lamps used in UK lights are designed to operate at the highest color temperature without getting too close to the burnout temperature (3000° - 3200° K.) They are filled with high pressure xenon gas (the best and most expensive) to retard filament evaporation and when necessary, some have small amounts of halogen gas added. High performance lamps may cost a little more, but the benefit is a whiter beam of light which makes illuminated objects appear more natural.
