OSRAM 64258 HLX — G4 20W 12V XENOPHOT bipin halogen lamp for fiber optics, microscopy and special luminaires
The OSRAM 64258 HLX is a reflectorless, low-voltage halogen lamp with a G4 base and XENOPHOT HLX ( xenon -filled) technology, designed for medical fiber optic light sources , microscopy , laboratory and analytical applications , and other precision lighting fixtures. It offers instant start-up , dimming , and a perfectly aligned filament thanks to patented quartz clamping for a homogeneous illuminated field in optical couplings. At 20 W/12 V , it delivers 350 lm with a CRI of 100 and a color temperature of approximately 3050 K , maintaining a virtually constant luminous flux throughout its rated lifespan of 2,000 hours . Its compact size ( Ø 9.5 mm , length 30.5 mm , LCL 19.5 mm ) simplifies replacement in compatible equipment.

Frequently Asked Questions
What advantages does HLX offer? The xenon filling increases luminous efficacy by up to 10% compared to standard halogen bulbs.
Is there a version with infrared (XIR) coating? Within the family, there are XIR versions with IR coating that achieve up to 30% greater efficiency. This reference is 64258 HLX (without XIR); if you require XIR, please specify this when selecting the model.
Can it be dimmed? Yes, it is dimmable . Use compatible power supplies/dimmers and do not exceed 12V RMS.
What does s90 mean? It is the combustion position recommended by the manufacturer to guarantee performance and nominal service life.
Compatibility, installation and safety
- Check compatibility: G4 , 12V , 20W and LCL 19.5mm .
- Respect the s90 position and the ventilation specified by the equipment manufacturer.
- Do not touch the capsule with your hands; handle with clean gloves.
- Always use in luminaires suitable for halogen lamps, with thermal screens/protections when required.
