Philips EHJ 7748XHP Halogen Bulb

The Philips EHJ 7748XHP is a 250-watt halogen bulb operating at 24 volts with a G6.35 two-pin base. It produces a 3400K colour temperature and a high colour rendering index of 100. This lamp is designed for specialist equipment such as overhead projectors, microfilm readers, medical devices, and stage or studio lighting fixtures.

Interface and Lifetime Limits

The G6.35 base requires a compatible socket and a stable 24-volt supply; it will not operate on mains voltage. The rated life is 50 hours, so the bulb is intended for intermittent use rather than continuous general lighting. Frequent replacement should be planned for in professional environments.

250-Watt Output Decides Suitability

At 250 watts the lamp delivers approximately 10000 lumens, a level that matches the original specification for many projectors and studio fixtures. If the equipment calls for a lower wattage or a different base type, this bulb will not be a correct fit. Buyers needing a longer-life or lower-heat alternative should look for a different technology.

Questions about this item

Should I choose the 250 W version or a lower-wattage alternative for my fixture?

This bulb is rated at 250 W and 24 V. Only install it in equipment that specifies exactly 250 W at 24 V with a G6.35 base; a different wattage will not match the fixture's power supply or optical design.

What does the 10 000 lumen rating mean when the bulb is running in a projector or studio light?

At 24 V the lamp produces approximately 10 000 lumens at a colour temperature of 3 400 K with a CRI of 100, delivering high-output white light for projection or stage use.

How does the G6.35 base limit what fixtures I can use this bulb in?

The G6.35 2-pin base has a 6.35 mm pin spacing and only fits sockets designed for that exact base; it cannot be used in GY6.35, G4 or any other base type.
