The Arri HMI 4k Fresnel kit is a high-efficiency, daylight-balanced (6000K) professional lighting system. It features a 4000 W lamphead with an 11.8" Fresnel lens that provides a smooth, even beam with a variable spread of 6.5° to 61°. Built with a rugged, weather-resistant housing (IP23 rating), the kit includes a flicker-free electronic ballast with DMX dimming, a 25-foot head-to-ballast cable, and 4-way barndoors. This compact unit delivers light output comparable to a 10k tungsten fixture while maintaining a lower power draw.
