Description
Metal Halide Lamps for TV, Film and Stage
The KLS KHD-4000HR/UVB is a 4000W hot restrike metal halide lamp engineered for the most demanding large-scale production lighting applications. Delivering an extraordinary 380,000 lumens at 6000K daylight color temperature with a CRI of ≥95, it produces the intense, accurate, and natural-looking light required for major film productions, large broadcast studios, and arena-scale stage events. The hot restrike capability allows immediate re-ignition after switch-off — critical in live production environments where every second counts. With a G38 base, 45,000V ignition voltage, and 500-hour rated life, it is a direct cross-reference replacement for Osram HMI 4000W/SE XS & Digital (54321), Philips MSR 4000W HR SE, GE CSR 4000/SE/HR, and Kyoto DIS-40H UV-B lamps.
