Purpose and fit

The OSRAM ELC3 is a 250 watt halogen bulb with a GX 5.3 two-pin base and a clear finish. It produces 550 lumens at a 3250K colour temperature and carries a 300-hour rated life. It suits stage, studio or projection fixtures that call for this specific lamp code.

Compatibility checklist

Verify that the fixture accepts a GX 5.3 base and is rated for 250 watts at 24 volts. Confirm the lamp compartment can accommodate a 1.989 inch diameter and a 1.765 inch overall length. Ensure the socket and wiring are designed for the heat output of a 250 watt halogen source.

Sustained-load behaviour

During continuous operation the filament maintains its 3250K output for the rated 300 hours before expected end of life. Surface temperatures rise quickly and remain high, so adequate fixture ventilation is required to prevent premature failure. The clear envelope transmits the full lumen output without diffusion losses.

Questions about this item

Does the 250W MR16 come with a GX5.3 socket or must I buy the fixture separately?

The bulb has a GX 5.3 2-Pin base that plugs into a matching socket; the fixture is not included.

Should I pick the 24V 300-hour version or a different voltage for studio use?

The 24V 300-hour rating suits low-voltage studio fixtures; other voltages would not match the 24V supply.

Will the 550-lumen output at 3250K be bright enough for a small projector?

550 lumens at 3250K provides warm white light typical for compact projection or stage spots.
