OSRAM 64670 T-18/T-25 (GCV) – Halogen Lamp 500 W 230 V GY9.5 for Fresnel and PC (3000 K, 11,000 lm)

The OSRAM 64670 T-18/T-25 (ANSI GCV / LIF T/25) is a single-cap halogen lamp with a GY9.5 base, designed for Fresnel and PC projectors in theaters, film/TV studios, and rental companies. It offers 3000 K (warm tungsten light), a CRI Ra of 100 , and a nominal luminous flux of 11,000 lm ( Φuse 10,280 lm), ensuring impeccable color rendering and a uniform beam. It is dimmable with the characteristic amber shift , maintains consistent color throughout its lifespan, and features a robust construction for demanding professional use.

Its compact geometry ( Ø 23 mm , length 90 mm ) and the 46.5 mm LCL with an 11 × 11 mm illuminated field facilitate stable focusing in standard luminaires with a GY9.5 socket. The recommended working position is s90 , and the nominal life is 300 h under suitable operating conditions.

Frequently Asked Questions

• Is it compatible with studio dimmers? Yes, it supports dimming with phase-cut dimmers suitable for 230V/500W.
• What is the difference compared to the 3200 K versions (e.g., CP/82)? This reference offers 3000 K and 11,000 lm ; other 500 W/230 V lamps may prioritize 3200 K and higher luminous flux, depending on their design. Check the color temperature and performance settings required for your production.
• Thermal or orientation requirements? Operate in the s90 position and in suitable luminaires, with high-temperature resistant materials and wiring.

Installation and safety

• Unplug and let the light fixture cool before handling; do not touch the quartz with your fingers.
• Always use studio halogen light fixtures with shields that contain fragments and control UV radiation and heat.
• Check mechanical ( GY9.5 , LCL 46.5 mm , 90 × 23 mm ) and electrical (230 V / 500 W) compatibility.
