Replacement Lamp for Professional Fixtures

The Philips MSD Platinum 17RA is a 350W metal halide discharge lamp built as a direct replacement for moving-head and spot fixtures used in stage, touring and installation lighting. It suits lighting technicians and venue operators who need a reliable, single-ended source that matches the original equipment specification. It is not for buyers who need an LED retrofit or a different wattage class.

Critical Fit: 1.0 mm Arc

The single specification that decides compatibility is the 1.0 mm arc length paired with a 38.7 mm working distance; the lamp must sit at that exact focal point for the fixture optics to produce a clean beam. The universal burning position allows any orientation, but the pinch temperature limit of 350°C means the fixture cooling must meet the original design. If the optical path or cooling differs, the lamp will not perform correctly.

Output Capacity and Service Life

Initial output ranges from 15,250 to 20,000 lumens at a 7000 K colour temperature with a CRI of 85, delivering the intensity and colour quality expected for professional stage wash and beam effects. Rated life is 1500 hours under standard operation; output will gradually decline and colour shift may appear as the lamp ages. It is not for users who require a longer maintenance interval or higher lumen maintenance over extended runs.
