OSRAM 64250 HLX (ESB) G4 6V 20W - Xenophot Halogen Lamp for Microscopy and Medical Fiber Optics
The OSRAM 64250 HLX is a low-voltage Xenophot (HLX) halogen lamp with a G4 base, designed for superior optical performance in microscopy, laboratory analysis, fiber optic illumination, and medical instrumentation . Compared to standard halogen lamps, HLX technology offers approximately 10% more luminous flux at the same wattage, while maintaining instant start-up , a CRI of 100 , and stable emission throughout its lifespan . It delivers 460 lm at 3350 K with an illuminated field of 2.3 × 0.8 mm² , ideal for efficient coupling in optical and fiber optic systems. Its compact size ( Ø 9 mm , length 31 mm , LCL 19.4 mm ) and universal burn-in position (Any) simplify integration and replacement in a wide variety of professional equipment.

Frequently Asked Questions
What differentiates HLX from a standard halogen bulb? The filling and design of the HLX family provide approximately 10% more luminous flux at the same wattage, with the same dimensions and base.
Is it dimmable? Yes. It can be dimmed with suitable equipment for resistive loads (the light becomes warmer when dimmed).
What is the working orientation? Universal (Any) , which facilitates its use in different positions within the luminaire or optical head.
Can the bulb be touched? No. Avoid contact of the quartz with your hands; clean with isopropyl alcohol if necessary.
Installation and safety
- Use only on compatible equipment/luminaires and, where appropriate, with shields that contain fragments and control UV/IR radiation.
- Verify 6V voltage and G4 socket before assembly. Ensure adequate ventilation and heat dissipation.
- The lamp reaches high temperatures during operation; allow to cool before handling.
