HPL - Medium Voltage (75-130 V)

OSRAM HPL lamps were originally designed for the Source Four series of fixtures, but are now used widely in the Entertainment Industry. The HPL uses an Ultra Compact Filament (UCF) design for maximum efficiency and life. The unique top bridgeless construction for lamps with ≤ 120 volts virtually eliminates filament shadowing, allowing for crisper images than ever before.
