OSRAM 64575 P1/15 EGY - Bi-pin halogen lamp 1000 W 230 V 3400 K (GX6.35 base)
The OSRAM 64575 is a high-performance bi-pin halogen lamp designed for professional applications in film, television, photography, and studio lighting. With 1000 W of power at 230 V , a color temperature of 3400 K , and a CRI of 100 , it delivers a warm white light with exceptional color fidelity. Its compact design, with a GX6.35 base , a diameter of 24.0 mm , and a total length of 67.5 mm, facilitates integration into studio lighting fixtures and heads. The 3400 K version maximizes luminous efficacy, delivering a reference luminous flux of approximately 33,000 lm (usable Φ use approx. 33,900 lm ), with instant start-up and stable performance throughout its short nominal life of 15 hours , typical of continuous beam, high-luminance lamps used for image capture.
It is regulated for use in entertainment and imaging equipment, allowing continuous dimming with the characteristic amber shift of tungsten lamps. The 38mm LCL (Light Center Length) , 14 x 14mm illuminated field , and 14mm filament help to concentrate the beam and optimize coupling with optics, Fresnels, and projection. It comes from the factory in individual boxes and master cartons of 12 units , commonly used in rental environments, studios, and theater companies.

Use cases
-
Studio lighting in TV, film and advertising: fresnels, open-face and projection heads.
-
Product and fashion photography when spectral continuity and natural transitions are sought.
-
Theatre and events as a continuous light source in venues with temperature and ventilation control.
Frequently Asked Questions
-
Can it be regulated? Yes, it supports continuous regulation with compatible dimmers for resistive loads.
-
What do EGY and P1/15 mean? They are equivalence codes: ANSI EGY and LIF P1/15 , to identify format and performance.
-
What is the difference between 3200 K and 3400 K? 3200 K is used as a TV/cinema standard for white balance; 3400 K prioritizes luminous efficacy (more light output) at the cost of a slightly shorter lifespan.
-
What is the correct working position? The OSRAM data sheet indicates the burning position “s”. Always use appropriate lighting and respect the manufacturer's ventilation and maximum temperature limits.
Compatibility and installation notes
-
Instant start and almost constant flow throughout its lifespan.
- Install in appropriate luminaires for high heat load halogen lamps and maintain effective ventilation .
- Avoid touching the bulb with your hands; grease shortens the life of the quartz.
