High-output metal-halide lamp

The OSRAM SYLVANIA HSD 250 W metal-halide lamp delivers 15000 lumens at a 7500 K daylight colour temperature. Its short-arc design produces crisp white light suited to stage, architectural and event installations. The single-ended GY9.5 base with outer jacket simplifies handling and fixture mounting.

Suited for professional lighting rigs

This lamp fits fixtures that accept a GY9.5 base and require high-intensity discharge output with a CRI of 85. It is not intended for residential sockets, low-wattage fittings or applications needing warm colour temperatures below 5600 K. Buyers needing dimmable operation or instant restrike should evaluate alternative technologies.

Capacity and headroom

Rated life reaches 6000 hours at full 250 W power, maintaining consistent output across that period. The 7500 K colour point sits within the 5600–7800 K daylight range specified for the series. Beyond the rated lifetime, lumen maintenance and colour stability will decline, requiring scheduled replacement.

Questions about this item

What fixture base is required for the GY9.5 socket on this 250 W metal halide lamp?

The lamp uses a GY9.5 base and must be installed in a compatible single-ended fixture designed for short-arc metal halide operation.

Can this 7500 K HSD lamp run on a magnetic ballast built for 5600 K metal halide lamps?

It requires a ballast rated for 250 W HSD short-arc metal halide types; colour temperature alone does not guarantee electrical compatibility.

How do I confirm the arc is striking correctly after installation?

The lamp should reach its rated 15000 lumen output with a crisp 7500 K daylight appearance and a CRI of 85 within the normal warm-up period.
