The ARRI L1.79250.B is a compact 250-watt tungsten fresnel spotlight, a precision tool for creating controlled illumination in film and television. It uses a 250-watt lamp and a genuine fresnel lens to produce a smooth, focusable beam that transitions from a wide flood to a narrow spot. This allows for versatile application as an accent, fill, or small key light with excellent field uniformity.

Built with a durable aluminum housing and effective thermal management, it includes a four-leaf barn door for beam shaping. The fixture operates at a consistent 3200K color temperature with a CRI of 100, ensuring perfect color fidelity under tungsten lighting conditions. It features a standard mounting yoke for easy integration onto stands or rigging.

A reliable and essential fixture for detailed lighting work, the 250W fresnel is valued for its optical precision and mechanical quality. Its low power draw and small size make it ideal for lighting tight spaces, product shots, or as an addition to larger setups where nuanced control is required.
