Professional Stage Lamp
The OSRAM HTI 1500W/60/P50 LOK-IT lamp is a single-ended metal halide source built for professional moving-head fixtures in stage, theater and touring applications. It produces 130000 lumens at 6000K with a colour rendering index above 85, giving clean white output and accurate colour for demanding lighting designs.
Upgrade From Lower-Output Lamps
This lamp replaces older 1500W-class lamps that deliver less output or poorer colour fidelity. The jump is worth it when a production needs the full 130000 lumen punch and Ra >85 for camera-friendly whites, especially in large venues or broadcast environments where every lumen counts.
Fixture Integration
The lamp fits fixtures designed for a 65.0 mm light centre length and a 6.1 mm cold electrode gap, matching the optical geometry of many 1500W-class moving heads. It runs at 100V and 15A nominal current, so the fixture must supply those electrical parameters. Rated life is 750 hours, after which output and colour stability will decline.

Questions about this item
What is the light centre length and electrode gap needed to align the lamp in a GTD-1500 II BEAM fixture?
The lamp has a 65.0 mm light centre length and a 6.1 mm cold electrode gap, which must match the fixture's optical plane for correct focus.
How is the lamp secured in the fixture, and what step is often missed during installation?
The Lok-it! base locks with a quarter-turn; the step often missed is verifying the pins click fully into the detents before powering on.
After how many hours should the lamp be replaced to maintain output and colour quality?
Nominal lifetime is 750 hours; plan replacement near this point to keep the 130,000 lm output and Ra >85 colour rendering consistent.
