The FDS 24V 150W Osram Sylvania halogen projection lamp is a professional-grade low-voltage tungsten halogen capsule engineered for precision optical equipment, slide projectors, microfilm readers, microscope illuminators, and studio applications. This T4 shape halogen bulb delivers 5000 lumens of brilliant 3450K white light with excellent color rendering, making it ideal for applications demanding faithful color reproduction and high-intensity illumination.

Built with a C-6 oval filament and precision-aligned quartz construction, this halogen lamp provides stable luminous output and consistent color temperature throughout its 100 life hours. The compact 2.25 inch overall length and 0.60 inch diameter T4 envelope seats into a GY9.5 2-pin pre-focus base, ensuring accurate optical alignment with no realignment required when replacing the lamp in projection or microscopy equipment.

This 24V 150W halogen bulb is a direct cross reference for the Osram 64643 (FDS), and is commonly specified for medical microscopes, ophthalmic instruments, fiber optic illuminators, dental examination lights, surgical lighting, microfilm readers, slide projectors, and studio optics. The lamp is dimmable when used with a compatible low-voltage transformer or regulated power supply, giving operators flexible control over output intensity.
