OSRAM CP70 64745 1000 W 230 V GX9.5 – Halogen lamp for studio and stage (3200 K, 26,000 lm)
The OSRAM CP/70 64745 (ANSI FVA) is a professional single-cap halogen lamp with a GX9.5 base, designed for studio, theater, TV, and photography applications . It offers a color temperature of 3200 K with a CRI of 100 for flawless on-camera color rendering, a nominal luminous flux of 26,000 lm , and an average lifespan of 200 hours . Its biplane (BP) filament and 13 × 15 mm light field ensure a uniform and easily focusable beam for compatible profiles , Fresnels, and softlights . It is fully dimmable and maintains instant start-up with virtually constant output throughout its lifespan, exhibiting the characteristic amber shift upon dimming.

Smooth regulation in conventional dimmers, with the warm look ( amber shift ) characteristic of tungsten.
-
Robust construction and simple maintenance in daily operation ( rental /fixed installation).
Use cases
-
Theatre and musicals : 1 kW fresnels and profiles for cutouts, frames and textures.
-
TV and studio : key/fill and backlighting with perfect color reproduction.
-
Photography and film : continuous tungsten lighting for small and medium sets.
-
Events and rental : standard replacement in parks of GX9.5 luminaires.
Frequently Asked Questions
-
Is it dimmable? Yes, it supports dimming with phase-cut dimmers suitable for 1 kW/230 V.
-
What is the working position? s90 (vertical with the bushing at 90° to the filament), as specified by the manufacturer.
-
What is the difference between nominal flux and Φuse ? Nominal flux is the total emitted; useful flux ( Φuse ) is measured at a reference angle and better describes the performance of luminaires.
-
Does it have thermal requirements? Yes: respect the maximum pinch temperature and the ventilation of the luminaire.
Installation and safety
- Handle with the equipment disconnected and the lamp cool; avoid touching the quartz with your fingers.
- Check compatibility GX9.5, LCL 55 mm and space for the bulb (Ø 26 mm, L 110 mm).
- Use high-temperature resistant lamp holders and cables ; do not operate near heat-sensitive materials.
- Respect the s90 position , the 6A (fast) fuse protection and the projector ventilation.
