OSRAM 64642 HLX - 150W/24V bi-pin halogen lamp without reflector for microscopy and fiber optics
The OSRAM 64642 HLX is a low-voltage, bi-pin (G6.35) reflectorless halogen lamp belonging to the XENOPHOT HLX family. It uses xenon gas instead of krypton, providing up to 10% more luminous flux compared to standard halogen lamps of the same wattage. With a nominal luminous flux of 150 W at 24 V , 5000 lm , and a color temperature of 3450 K (CRI 100), it offers instant light , stepless dimming , and precise filament alignment for efficient coupling in demanding optical systems.
Its compact geometry (Ø 11.5 mm and total length of 50.0 mm) and illuminated field of 6.0 × 3.2 mm² facilitate focusing and light delivery in microscopy , fiber optic illumination , UV curing , and other specialized lighting applications in the medical, scientific, and industrial fields. The s90 firing position and the 31.7 mm LCL (Light Center Length) ensure photometric consistency in compatible equipment. Nominal lifespan: 300 h .

Frequently Asked Questions
-
Is it compatible with my equipment? Check the G6.35 socket, the LCL 31.7 mm , the s90 position and the power/voltage ( 150 W/24 V ) indicated by the instrument manufacturer.
-
Can it be dimmed? Yes. It is dimmable with suitable 24V halogen power supplies/drives.
-
What is its lifespan? 300 hours nominal. Replace if the intensity decreases or when the recommended end of life is reached.
-
Does it require special equipment? It must be operated with suitable 24V AC power supplies/transformers and luminaires designed for halogen capsules.
