OSRAM 64751 P2/12 - Linear halogen lamp 1,250 W 230 V R7s for cinema, TV and stage

The OSRAM 64751 P2/12 is a double-ended (R7s) studio halogen lamp designed for professional lighting in film, television, theater, and events . It offers a color temperature of 3200 K (studio tungsten), a CRI of 100 , and a luminous flux of 33,500 lm , with an efficacy of 27.6 lm/W . Its 200-hour rated life and continuous dimming capability make it a standard for cyc lights , softlights , and linear projectors. With a total length of 185.7 mm and a diameter of 12 mm , it integrates easily into compatible fixtures and supports a p15 burn-in position (horizontal ±15°) for stable performance.

Frequently Asked Questions

Is it dimmable? Yes, it is 100% dimmable with the characteristic amber shift of tungsten when dimming.

What is the working orientation? p15 , that is, horizontal operation with an approximate tolerance of ±15°.

How does it differ from a domestic R7s? This 1,250 W, 3,200 K P2/12 version is designed for professional use (higher luminous flux, CRI 100 and specific nominal life) and requires suitable luminaires and ventilation .

Installation and safety

• Always install in suitable studio halogen luminaires with thermal protection.
• Avoid touching the quartz with your fingers; use clean gloves or a lint-free cloth.
• Respect position p15 and ensure ventilation to maintain working temperature.
