OSRAM CP39 / CP68 64721 – Halogen lamp 650 W 230 V G22 for studio and theater (3200 K, 16,800 lm, 100 h)

The OSRAM CP39 (also known as CP68 in some listings), reference 64721 , is a professional halogen lamp with a G22 base, optimized for film/TV, theater, and entertainment applications . It delivers 16,800 lumens at 3200 K (CRI 100) with a uniform and easily focusable beam thanks to its biplane filament and 13 × 17 mm illuminated field . Designed for intensive use in studio projectors (Fresnel, profile, and open-face ), it is fully dimmable , with the characteristic amber shift of tungsten. Its 63.5 mm LCL , 140 mm overall length , and 26 mm diameter facilitate replacement in G22- compatible fixtures. Typical lifespan: 100 hours .

Frequently Asked Questions

• Are CP39 and CP68 equivalent? OSRAM labels this lamp as CP/39 (ANSI FKH ); other catalogs indicate CP/68 as the equivalent LIF designation for 650W G22. Always check the dimensions (LCL 63.5 mm) and the socket.
• Is it dimmable? Yes, it accepts phase-cut dimmers for 230V/650W.
• What is the lifespan? Typical lifespan in professional applications is ~100 h (high performance at 3200 K).

Installation and safety

• Handle the lamp cold and with gloves; avoid touching the quartz.
• Check the s90 position and compatibility with LCL 63.5 mm and Ø 26 × 140 mm .
• Use high-temperature resistant lamp holders and wiring; do not operate near heat-sensitive materials.
