OSRAM 64719 T/12 (T-21) 650W 230V GX9.5 - Halogen Studio Lamp for Theatre, Film and TV

OSRAM 64719 T/12 (T-21) 650W 230V GX9.5 - Halogen Studio Lamp for Theatre, Film and TV

The OSRAM 64719 T/12 650W 230V with a GX9.5 base is a single-terminal halogen lamp designed for professional studio, theater, concert, film, and TV lighting . It offers a color rendering index ( CRI) of 100 with a nominal color temperature of 3000K and a useful luminous flux of 11,280 lm (12,000 lm nominal), guaranteeing continuous, stable, and dimmable light with the characteristic amber shift of halogen lamps. Its robust construction and industry-standard dimensions— 26 mm diameter, 110 mm length, and 55 mm LCL —facilitate replacement in a wide range of GX9.5- based fixtures. The nominal lifespan is 750 hours , and the recommended operating position is s90 (base down to horizontal), ensuring consistent performance in compatible profile, Fresnel, and studio spotlights.

Product benefits

• Consistent color and CRI 100: ideal for cameras and skin, with natural tones on stage and set.
• Smooth regulation: flicker-free dimming with a warm transition when dimming, favoring scenic atmospheres.
• Industry standard: T/12 geometry and 55mm Light Center Length simplify replacement on compatible GX9.5 spotlights.
• Robustness and reliability: construction designed for intensive use in theater and studio.
• Useful illuminance: certified useful flux (Φ _use ) that facilitates the planning of actual light levels.

Use cases

• Theatre and concert halls: Fresnel, PCs and 650W cutouts for cutouts, backlights and keys in script or musical theatre.
• TV and film studio: key/fill/back light in small studios and mobile sets that require precise beam control.
• Events and tours: stage lighting and spot reinforcement where continuous light and fine adjustment are needed.

Frequently Asked Questions

• Is it compatible with my GX9.5 bulb? Yes, provided the manufacturer specifies T/12 lamps of 650W, 230V, LCL 55mm and GX9.5 base. Check the space, wattage, and ventilation of the light fixture.
• Can it be dimmed? Yes, it's dimmable. As with all halogen bulbs, dimming lowers the color temperature ( amber shift ).
• What is its lifespan? 750 nominal hours under proper usage and ventilation conditions.
• What is the working position? Recommended s90 (from base down to horizontal) for optimal performance.
• Is there a 3200K variant? Within the studio halogen line, there are 3200K models for cinema/TV. This reference 64719 is 3000K.

Safety and proper use

• Use only in suitable luminaires with protective screens or grids that contain fragments in case of failure.
• Avoid direct exposure to UV radiation ; use optics and filters from the luminaire manufacturer.
• The lamp reaches high temperatures ; do not touch the bulb with your hands (use gloves) and let it cool before handling.
• Respect the operating position and ventilation of the light fixture to preserve its useful life.
