High-output halogen lamp

The OSRAM SYLVANIA 64654 HLX delivers 9000 lumens from a 250 watt halogen capsule. It runs on a 24 volt supply and fits fixtures with a GY9.5 bi-pin base. The T4 tubular envelope suits compact optical systems in studio, stage or medical equipment.

Thermal behaviour and power

At 250 watts the lamp converts most input power into heat, so the fixture must tolerate high surface temperatures. The 300 hour rated life reflects the elevated filament temperature needed for a colour rendering index of 100. No active cooling is built into the lamp itself.

Base and envelope implications

The GY9.5 base with 9.5 millimetre pin spacing locks the bulb securely in matching sockets. The slender T4 quartz envelope requires clean handling to avoid hot spots that shorten life. Buyers needing longer service intervals or lower heat output should consider alternative lamp technologies.

Questions about this item

How do I install the GY9.5 base into the fixture without damaging the pins?

Align the two 9.5 mm spaced pins with the socket holes, press straight in until seated, and avoid touching the quartz envelope with bare fingers to prevent hot spots.

What maintenance or replacement will this 250 W halogen bulb need over time?

The lamp is rated for 300 hours; plan to replace the bulb once it reaches that limit, as halogen output drops sharply near end of life.

What limit appears first when running the 24 V 250 W bulb continuously at full power?

The 300 hour rated life is the primary limit; sustained operation at 250 W will reach that point before any other degradation becomes noticeable.
