OSRAM 64515 300W/230V GX6.35 – T6 bipin halogen lamp for cinema, TV, photography and stage sets (3300 K)
The OSRAM 64515 300W/230V is a single-ended tungsten halogen lamp (T6) with a GX6.35 base, designed for professional film, television, photography, and theater applications. It delivers a nominal luminous flux of 9,600 lm ( useful Φ: 10,035 lm ) with a color temperature of 3300 K and a CRI of 100 , offering faithful color rendering and consistent illumination throughout its short nominal lifespan of 15 hours , making it suitable for peak performance in demanding productions. It incorporates quartz clamping technology for enhanced thermal robustness, is dimmable, and features an S90 burn-in position (use within ±90° of the vertical), facilitating its integration into various professional lighting setups.

-
Professional studio photography : modeling lamps or continuous light in compatible heads.
-
Theatre and stages : compact spotlights, effects and precision lighting.
-
Projection and photo-optics in equipment that specifies 300 W / 230 V GX6.35.
Frequently Asked Questions
-
Is it dimmable? Yes. It can be used with compatible halogen dimmers. When dimming, an amber shift (warmer tone) is normal.
-
What is the s90 burn position? It allows the lamp to be operated within ±90° of the vertical (flexible orientation in most luminaires).
-
Does it need a transformer? No. This item is designed for 230V AC (mains voltage).
-
Does it emit UV or heat? Yes, like all quartz halogen lamps, it emits UV radiation and heat. Always use appropriate light fixtures with filters or protective screens.
-
Are there any variations? Within the same family, there is also a 64515 300 W / 240 V version. Always verify the voltage required by your equipment.
Installation and safety recommendations
- Handle the quartz bulb with clean gloves or a lint-free cloth; wipe off any fingerprints before switching on.
- Install the lamp only in approved and enclosed luminaires , with screens/deflectors that contain fragments in case of breakage.
- Respect the s90 burn position and ensure sufficient ventilation to dissipate heat.
- Do not touch the lamp when hot; wait for it to cool before replacing or adjusting.
