Stage Lighting Source

The Philips MSR 400 SA is a 400W short arc HID bulb built for professional stage and studio fixtures. It delivers 23500 lumens at a 5600K colour temperature with a CRI of 75, making it suitable for productions that need intense, daylight-balanced output from a compact arc gap.

Output Capacity and Limits

The lamp runs at 207V and is rated for 750 hours of life, providing high beam intensity for its rated duration. It covers the needs of medium-throw follow spots and compact moving heads, but the 750-hour rating means frequent changeovers for long-running shows or venues operating daily.

Build and Mounting Practicalities

The GY9.5 2-pin prefocus base ensures precise alignment in compatible luminaires, while Philips P3 technology allows operation at higher temperatures in any burning position. This construction supports consistent output and fewer early failures, though the specialised base limits use to fixtures designed for the GY9.5 interface.

Questions about this item

Will the GY9.5 2-Pin Prefocus base fit my existing 400 W fixture and ballast?

The lamp uses a GY9.5 2-Pin Prefocus base and runs at 400 W / 207 V, so it matches fixtures and ballasts rated for that wattage and voltage combination.

How can I confirm the 5600 K colour temperature and 23500 lumen output are being delivered after installation?

A stable, white 5600 K beam at the rated 23500 lumens with no flicker indicates the arc is operating correctly on the 207 V supply.

Does the box include a replacement ballast or only the HID bulb itself?

Only the Philips MSR 400 SA short-arc HID bulb is supplied; a compatible 400 W / 207 V ballast must be sourced separately.
