OSRAM 64647 120 W 24 V (G6,35) - XENOPHOT HLX bipin halogen lamp for microscopy and fiber optics
The Osram 64647 120 W 24 V is a low-voltage bipin halogen lamp with a G6.35 base, designed for demanding technical lighting and optical equipment. It offers a nominal luminous flux of 3,600 lm with a CRI of 100 and an illuminated field of 2.3 × 6.4 mm² , ideal for light guide systems and precision optics. The XENOPHOT HLX versions use xenon gas instead of krypton, achieving up to 10% greater efficacy/flux with the same power consumption and instant start-up . Its compact geometry (Ø 13 mm , 44 mm length, LCL 30 mm ) facilitates integration in microscopy, medical fiber optics, laboratory/inspection, and UV curing applications . It is dimmable , supports universal working positions , and, according to the current datasheet, has a nominal lifespan of up to 1,000 hours .

Frequently Asked Questions
What's the difference between the standard version and the XENOPHOT HLX? The HLX uses xenon gas instead of krypton, providing up to 10% more light output and instant response, while maintaining the same dimensions and cap.
Can it be dimmed? Yes, it is fully dimmable . To maximize its lifespan, avoid rapid cycling and ensure adequate ventilation.
Does it work on DC? AC power is recommended; some devices may use stabilized DC, but prolonged use on DC may shorten filament life.
Are there any precautions to take when installing it? Do not touch the quartz bulb with your fingers; use clean gloves. Always operate in enclosed and compatible fixtures.
Technical note on useful life
The nominal service life indicated by Osram in the current technical data sheet is up to 1,000 hours . Some previous data sheets and listings for this part number show 700 hours ; this difference is due to revisions and testing conditions. Consult your equipment documentation for the actual operating life.
