OSRAM 64655 HLX (EHJ) - Bi-pin halogen lamp 250 W, 24 V, G6.35 (XENOPHOT · 50 h)

OSRAM 64655 HLX (EHJ) - Bi-pin halogen lamp 250 W, 24 V, G6.35 (XENOPHOT · 50 h)

The OSRAM 64655 HLX is a low-voltage, reflectorless halogen lamp with a G6.35 base, widely used in microscopy , fiber optic illumination , laboratories, analysis, and UV curing. It belongs to the XENOPHOT (HLX) family, which uses xenon as a fill gas to offer up to 10% more luminous flux than standard halogen lamps with the same power consumption. It provides 10,000 lm at 3,550 K , has a CRI Ra 100 , a nominal life of 50 hours , and is dimmable . Its filament is precisely aligned for a stable beam geometry and optimal coupling to fiber optic systems or collectors. The s90 burn-in position allows operation in a wide range of orientations around the vertical.

Main features

• HLX performance: up to +10% flow with the same consumption compared to conventional halogen lamps.
• Power/Voltage: 250 W · 24 V (AC).
• Light and color: 10,000 lm · 3,550 K · Ra 100 .
• Precision optics: 7.1 × 3.6 mm² illuminated field and 33 mm LCL for stable focusing.

• Compact construction: Ø 12.5 mm · length 55 mm .
• Working position: s90 (±90° with respect to the vertical).
• Nominal life: 50 h .

Product benefits

• More light with the same power: XENOPHOT HLX technology to maximize usable output.
• Reference color rendering: Ra 100 for true color in inspection and display.
• Photometric stability: virtually constant flux throughout the service life.
• Simple integration: standardized measurements and aligned filament for efficient coupling to optics/fibers.
• Total control: instant start and smooth dimming .

Use cases

• Microscopy and scientific imaging systems.
• Fiber optic lighting in medical and inspection equipment.
• Laboratory and analysis ; UV curing (with equipment's own optics/filters).
• Suspended surgical and dental lighting (depending on equipment compatibility).

Frequently Asked Questions

• What does HLX mean? It's OSRAM's XENOPHOT designation: the use of xenon as a fill gas for +10% flux compared to standard lamps.
• Is it dimmable? Yes, it supports dimming with regulators suitable for the system.
• What does s90 indicate? It means that the lamp can operate within ±90° of the vertical , offering great freedom of mounting.
• Safety recommendations? Use in suitable luminaires with screens/protections that contain fragments in case of breakage and avoid exposure to UV/IR. High operating temperature must be clearly indicated.

Installation and best practices

• Check 24V at terminals; overvoltage drastically reduces lifespan.
• Handle with gloves or cloth; do not touch the quartz.
• Respect the LCL 33 mm for focusing on the optical system.
• Ensure ventilation in the light fixture and avoid vibrations.
