GE 22494 CSR1200/S/DE

The GE 22494 CSR1200/S/DE is a high-intensity 1200W double-ended short-arc quartz metal halide lamp engineered for professional SSTV (stage, studio, and theater) film and broadcast lighting, concert touring moving head fixtures, stadium-level entertainment systems, and high-intensity outdoor projection. Delivering 110,000 lumens of 6000K daylight output at 90 CRI and 91 lm/W through a double-ended SFc15.5-6 base, this DC-powered CSR lamp provides a 750–1,000-hour rated service life for demanding production and broadcast environments.

ADL Supply Expert Application & Replacement Guide

The GE CSR1200/S/DE (Order Code 22494) is primarily specified by studio lighting technicians, concert tour gaffers, broadcast engineers, and entertainment equipment service teams as the replacement arc source in large-format moving head fixtures, arena follow spots, film studio HMI-class luminaires, and high-intensity outdoor projection systems where 1,200W double-ended short-arc output and 6000K daylight balance are required. This lamp is part of the CSR (Compact Source Rare-earth) platform and operates on DC current from a dedicated electronic ballast specifically designed for CSR/SSTV double-ended short-arc lamp operation — standard AC metal halide ballasts are not compatible. The 100V is the lamp's operating arc voltage at DC, not an AC supply voltage. The fixture's internal electronic ballast converts AC mains power to regulated DC. The SFc15.5-6 double-ended base uses a 15.5mm cap diameter with 6 contact points at each end — installation requires correct seating in both lamp house cap sockets before powering, with the cap locking mechanisms engaged. The burn position is horizontal ±15° — confirm this matches the lamp house mounting geometry. Production facilities should track runtime hours and schedule preventive replacement before the 1,000-hour threshold.

Operation, Safety & Mounting Compliance

DC Power Requirement, Double-Ended Installation & Hot Restart

CSR short-arc lamps operate on regulated direct current from a dedicated electronic ballast — the DC arc current provides stable, flicker-free output required for broadcast and film production color grading. Standard AC metal halide ballasts lack the electrical characteristics required for CSR arc tube operation and must not be substituted. Both SFc15.5-6 end caps must be correctly seated and locked in the lamp house's double-ended cap sockets before powering — a partially engaged cap at either end creates a poor electrical contact that generates resistance heating and is a fire risk at this wattage class. Following any power interruption, allow at least 15 minutes cool-down before attempting to restrike — the arc tube pressure must normalize before re-ignition can succeed.

High-Pressure Safety, UV Hazard & Quartz Handling

At 1,200W this lamp operates at extreme internal pressure and temperature — always wear a full face shield and protective gloves during all handling, installation, and removal procedures. Never handle the quartz envelope with bare skin — skin oils create localized hot spots that accelerate premature envelope failure at these operating conditions. This lamp emits high levels of UV radiation and must be installed exclusively in an approved enclosed luminaire with UV-filtering shielding that can also contain hot fragments in the event of envelope rupture. This lamp contains mercury and must be recycled through a certified lamp recycling program.
