Osram also announced the average life of the HSD 150/70 metal halide lamp operated with electronic control gear (ECG) is now 3000 hours - a 50% improvement. The HSD 150/70 is up to three times brighter than comparable lamps of the same power consumption in spotlights with optical paths, say Osram, and has a colour temperature of 7000K.
Finally, Osram re-launched the single-ended HTI 705 W/SE short-arc lamp, now with a colour temperature of 5500K. With a rated output of 700W and an initial luminous flux of 59,000 lumens, the lamp is particularly suitable for use in effect lighting for theatre, shows, musicals, rock concerts and other major events, say Osram.
