The ARRI True Blue T5 is a high-output 5000-watt tungsten fresnel spotlight designed for demanding location and studio work where a powerful, hard light source is required. It utilizes a massive T24 5000-watt tungsten halogen lamp within a precision-engineered fresnel lens system to produce an intense, focusable beam capable of throwing long distances and cutting through ambient light. This fixture is a workhorse for lighting large areas, such as building exteriors, large studio sets, or as a strong key or backlight in daylight-matching scenarios when used with appropriate blue-grade correction gels (hinted at by the "True Blue" designation).

Built with durability for location use, it features a robust steel housing, an efficient cooling system to manage the substantial heat output, and a heavy-duty yoke for secure mounting on large stands or rigging. It includes a four-leaf barn door system for beam shaping and spill control. Operating at a standard 3200K color temperature with a perfect CRI of 100, it provides impeccable color rendering, though its high power consumption and heat generation necessitate careful planning for power distribution and crew safety.

The True Blue T5 represents the pinnacle of traditional high-power tungsten lighting. It is a trusted tool for cinematographers and gaffers on major film and television productions who require an unmatched level of controllable output and reliability from a continuous light source, capable of creating dramatic, high-contrast lighting effects or serving as a foundational wash for vast spaces.
