OSRAM HMP lamps, such as the OSRAM HMP 400 DE (Sylvania light bulb part number 54146) have been especially designed to maintain their effectiveness even when dimmed or boosted. This is especially important when both overhead transparencies and LCD displays are included in the same overhead projection presentation. Voltage can be increased to boost the light levels for the LCD portions of the presentation and reduced to balance the light output for the transparency portion. The special feature can easily be extended to any setting where you need them, and it does not affect the quality of the light output whatsoever. The color temperature of this type of bulb is between 4500K and 6500K, with a CRI range of 80-95.

HMP light bulbs are relatively recent innovations from OSRAM and are tailored specifically to the requirements of overhead projection. Originally, they were used in the 1972 Munich Olympics to provide the best possible TV pictures. Of course, the technology was successful and put into worldwide use in many areas. These bulbs are generally used in specialized applications for overhead projection devices, as well as other types of projection scenarios. Another common use is in special effect lighting for party planners, movie production crews, or live stage production crews. They are really flexible products that suit the high demands of those fields while maintaining full light output and light quality.
