EFP/X is a separate extended-life version. Other 12 V, 100 W MR16 lamps can differ in reflector geometry, working distance, thermal behavior, or filament alignment; match the complete EFP identity.
These references are organized from established EFP equipment-reference records. Equipment revisions can vary; confirm ANSI EFP, 100 W, 12 V, GZ6.35, and the required reflector/working-distance specification before ordering.
