OSRAM HMI Digital 400W GZY9.5 base 6900K metal halide bulb - UV stop quartz. Excellent hot-restart. Application: FILM, TV & VIDEO PRODUCTION

Weather using film or shooting with a digital camera in modes of 1000 Hz and higher, the OSRAM HMI DIGITAL line has a lamp for your production. While specially designed to accommodate evolving, high-speed film technology, HMI DIGITAL still provides every feature needed to light traditional film productions, as well as theater stages.

The Osram 55073 HMI DIGITAL 400W is the direct replacement with the same performance characteristics for Osram 53978 HMI 400 W/SE/UVS. The only difference is the new lamp is designed to also operate more smoothly at higher operating frequencies on newer fixtures with high-speed ballasts.
