Philips MSA 2500 DE (SFc) - 2,500 W, 5,600 K, 250,000 lm Metal Halide Lamp for Architectural and Theatrical Projectors
The Philips MSA 2500 DE ( Architectural MSA/MHN-SA family) is a double-ended SFc metal halide lamp designed for high-power projectors in architectural lighting, stage lighting, and color-changing equipment (e.g., City Color). Its compact 25 mm arc and optimal halide blend deliver 250,000 lumens at 5,600 K (color code 856 ) with a typical CRI of 88 , achieving high-intensity beams and well-balanced color rendering. It operates at 22.5 A with a power rating of 2,500 W , has a P15 operating position (parallel ±15° or horizontal), and is not dimmable. It is designed for enclosed luminaires and provides an average lifespan of 2,500 h , with compact dimensions ( Ø 41 mm and length 364 mm ) that facilitate optical control and integration into large format projectors.
Main features
-
High luminous efficacy: 250,000 lm and 100 lm/W nominal for maximum beam intensity.
-
Daytime stable color: 5,600 K , CRI 88 (code 856 ) with chromaticity coordinates x 0.330 / y 0.360 .
-
Short 25mm arc: greater concentration of flow and better use of optics.
-
Double SFc socket: robust and secure fixing in professional equipment; P15 position (parallel ±15° or horizontal).

-
Minimum ignition voltage: 198 V.
-
Average lifespan: 2,500 h (at 50% failure rate).
-
Dimensions: Ø 41 mm · length 364 mm · arc 25 mm .
Product benefits
-
Maximum visual power for facade illumination , long-distance projections , and large stages.
-
Consistent color (5,600 K) that facilitates mixing with daylight sources and camera work.
-
Precise optical control thanks to the short arc, with more concentrated beams and greater "punch".
-
Professional integration in SFc dual-cap projectors and 2.5 kW color changer equipment.
Use cases
-
Exterior architectural lighting: facades, monuments, skyscrapers and bridges with large format projectors.
-
Shows and touring: wash and long-distance projection at festivals and special events.
-
City Color type color changers and similar 2.5 kW equipment specified for MSA/MHN-SA 2500 DE (SFc).
Frequently Asked Questions
-
Is it dimmable? No. This lamp does not support dimming ; it must operate at its rated wattage with appropriate equipment.
-
What orientation should I maintain? P15 : parallel ±15° or horizontal . Maintain this position to ensure flow and service life.
-
Does it contain mercury? Yes. Dispose of at an authorized facility and follow safety recommendations.
Safety and recommendations
Always use in enclosed luminaires compatible with 2.5 kW metal halide lamps. In case of breakage, ventilate for 30 minutes , collect with gloves, and place in a sealed bag for recycling. Do not use a vacuum cleaner.
