Halogen bulb for projection and medical use

The OSRAM SYLVANIA 64637 EFP/LL is a 100W 12V MR16 halogen lamp with a GZ6.35 two-pin base and a rated life of 1500 hours. It delivers a colour rendering index of 100 for accurate colour reproduction in projection lamps, medical equipment and stage lighting fixtures.

Check voltage and base before ordering

Confirm that your fixture operates on a 12V supply and accepts a GZ6.35 bi-pin base with 6.35 mm pin spacing. The reflector has no alignment stud, so the socket must not rely on a stud for lamp positioning. Verify the maximum wattage rating of the fixture to ensure it supports 100W operation.

Replaces standard EFP lamps with longer life

This bulb serves as a direct replacement for standard EFP halogen lamps while extending the rated lifespan to 1500 hours. The upgrade is worthwhile when longer service intervals reduce maintenance on projection, medical or stage lighting systems that currently use shorter-life EFP types.

Questions about this item

Does the bulb come alone or with a fixture and transformer?

Only the MR16 halogen lamp is supplied; a compatible 12 V fixture and transformer must be purchased separately.

Should I choose this 100 W version or a lower-wattage MR16 for my projector?

Select the 100 W model when the equipment specifies a 100 W EFP/LL lamp; a lower-wattage bulb will not deliver the required light output.

What does the 1500-hour rating mean for daily stage use?

At roughly four hours per show the lamp lasts about a year before output drops below specification.
