OSRAM 64265 HLX (Xenophot) - G4 30W 6V bipin halogen lamp without reflector for microscopy and fiber optics
The OSRAM 64265 HLX belongs to the Xenophot (HLX) series, which replaces krypton with xenon as the fill gas to offer up to 10% more luminous flux with the same energy consumption compared to standard halogen lamps. It is a reflectorless, low-voltage halogen lamp with a G4 (bipin) base, designed for microscopy , laboratory and analytical applications , light guide illumination , and UV curing . It delivers 765 lm at 6 V / 30 W with a color temperature of 3200 K and a CRI of 100 , and is dimmable . Its compact geometry ( Ø 9 mm , length 31 mm ) and LCL of 19.5 mm with an illuminated field of 1.6 × 1.6 mm² facilitate efficient coupling to collectors and fibers. It offers an "Any" burn position and a nominal lifespan of 100 h , with an approximate weight of 1.18 g .

Compatibility and common models (examples)
It is commonly used as a replacement bulb in microscopes from Olympus (e.g., BX41 ) and Nikon (e.g., Eclipse E400 ), among others, provided the equipment specifies 6V/30W with a G4 base. Compatibility depends on the lamp holder/cassette of each manufacturer; please check the equipment reference before purchasing.
Frequently Asked Questions
-
What does HLX mean? It identifies Xenophot technology (filled with xenon) that provides approximately 10% more flux than standard halogen bulbs.
-
Can it be adjusted? Yes, it is adjustable with compatible power supplies/drives.
-
Does orientation matter? This reference supports burn position in any orientation ( Any ).
-
Useful life? Approximately 100 hours under nominal conditions.
Usage and safety recommendations
- Use only in luminaires or enclosed housings suitable for halogen lamps due to high temperature and radiation.
- Avoid touching the bulb; install with clean gloves to avoid shortening the lifespan.
- Respect the nominal voltage (6 V) and the correct thermal dissipation of the equipment.
