OSRAM GLF 235W Halogen Bulb

The OSRAM GLF is a 235 watt halogen lamp that runs on 230 volts and uses a G5.3 bipin base. It produces 5100 lumens at a 3100K colour temperature with a colour rendering index of 100. The rated life is 100 hours. It is built for fixtures that accept this specific wattage and base type.

Installation Notes

Align the bipin base with the socket and press firmly until the pins seat fully; the lamp is single-ended so orientation is fixed. Handle the quartz envelope only with a clean cloth or gloves because skin oils create hot spots that shorten the already brief 100-hour life. Verify the fixture is rated for 235 watts before fitting to avoid overheating the housing or wiring.

Suitability

This lamp suits stage, studio or specialist fixtures that demand high output and perfect colour rendering for short periods. Buyers needing a long-life general-purpose bulb should look elsewhere because the 100-hour rating requires frequent replacement. It is also unsuitable for any socket other than G5.3 or for voltages other than 230 volts.

Questions about this item

How can I confirm the OSRAM GLF bulb is operating correctly after installation?

The bulb should emit a steady 3100 K white light at its rated 5100 lumen output when powered at 230 V; any flickering, dimming or colour shift indicates a problem.

What is included with the SYLVANIA OSRAM GLF halogen bulb and what must be purchased separately?

The package contains the single G5.3 bi-pin halogen bulb only; a compatible 230 V fixture with a G5.3 socket is required but not supplied.

Which version of the GLF bulb should I choose for a fixture rated at 235 watts and 230 volts?

Select the 235 W, 230 V model with a G5.3 base and 3100 K colour temperature — this is the only variant that matches those exact electrical and physical specifications.
