Professional stage lamp

The OSRAM HTI 1500W/60/P50 LOK-IT 54225 is a single-ended metal halide lamp built for professional stage, theater and touring moving-head fixtures. It serves lighting designers and rental houses that need reliable high-output illumination for large venues and long-throw applications.

Thermals noise and power

The lamp runs at 1500 W nominal power with a 100 V supply and draws 15 A nominal current during operation. Its 750-hour rated lifetime reflects the thermal load typical of continuous touring use, while the LOK-IT base ensures secure electrical contact under vibration and heat cycling.

130000 lumen output

A massive 130000 lm output at 6000 K with Ra greater than 85 delivers clean whites and accurate color for demanding productions. The 65.0 mm light center length and 6.1 mm cold electrode gap align precisely with compatible optics in fixtures such as the Clay Paky Alpha Profile Video and other 1500 W-class heads.

Questions about this item

How do I install the LOK-IT 54225 lamp in my Claypaky Alpha Profile Video fixture, and which alignment step is critical?

Insert the lamp base into the LOK-IT socket until it locks, then verify the 65.0 mm light center length matches the fixture's optical axis; the 6.1 mm cold electrode gap must sit precisely in the reflector focal point or output will be misaligned.

What maintenance or replacement will the OSRAM HTI 1500W/60/P50 lamp need after extended use?

Replace the lamp after 750 hours of operation; monitor output for lumen depreciation and color shift beyond the Ra >85 threshold, and inspect the quartz envelope for devitrification or electrode erosion during scheduled fixture servicing.

What is the first limit that appears when running this 1500W metal halide lamp continuously at full power?

The 750-hour nominal lifetime is the primary limit; sustained 15A current at 100V drives envelope temperature toward the 130000-lumen design ceiling, accelerating electrode wear and quartz devitrification before other components fail.
