OSRAM 64633 HLX - Halogen lamp 150 W 15 V G6.35 XENOPHOT without reflector (BRJ, A1/234)

OSRAM 64633 HLX - Halogen lamp 150 W 15 V G6.35 XENOPHOT without reflector (BRJ, A1/234)

The OSRAM 64633 HLX is a reflectorless, low-voltage halogen lamp with a G6.35 base and a power rating of 150 W at 15 V, belonging to the XENOPHOT (HLX) family. It uses xenon gas as the fill gas to deliver up to 10% more luminous flux compared to standard halogen lamps with the same power consumption, while maintaining instant light , smooth dimming , and a stable beam throughout its lifespan. With 5,600 lm , 3,450 K , and a CRI of 100 , it is optimized for microscopy , fiber optic illumination , medical equipment (operating room/dental) , laboratory and analytical applications, as well as other specialized projection and industrial lighting.

Its filament is precisely aligned for an illuminated field of 3.0 × 4.8 mm² , with a 30.0 mm LCL and compact dimensions ( Ø 11.5 mm , length 44.0 mm ). The rated life is 50 hours , and the S90 burn-in position provides mounting flexibility in professional equipment. International identification: ANSI BRJ and LIF A1/234 .

Frequently Asked Questions

What does HLX/XENOPHOT mean? It indicates the use of xenon as a fill gas, which provides up to 10% more luminous flux compared to standard halogens.

Is it dimmable? Yes, the lamp is dimmable . Use compatible transformers/dimmers for low-voltage (15V) halogen loads.

What is the LCL? The LCL (Light Center Length) is 30.0 mm . The value of 3.0 mm corresponds to the filament length , not the LCL.

What are its reference codes? ANSI BRJ and LIF A1/234 ; OSRAM reference 64633 HLX .

Good installation practices

• Handle the bulb with clean gloves to avoid residue that creates hot spots.
• Verify that the equipment provides 15V AC and adequate ventilation of the housing.
• Ensure precise lamp alignment in optical systems to take advantage of the 3.0 × 4.8 mm² illuminated field.
