Overview
The TX-5266W300 is a 300 W ultra-high-power white COB LED module on a 52 × 66 mm substrate with a Φ14.1 mm light emitting surface, delivering 30,000–36,000 lm in the CRI 70 daylight build and 21,500–24,800 lm in the CRI 95 studio build.
Two factory-calibrated CCT variants share the same footprint: a 7500–8500 K daylight version for maximum punch, and a 3200 K / 5600 K dual-binned version with CRI 95 for camera-critical film and broadcast work. Both are drop-in replacements on the same 52 × 66 mm mounting pattern and share the same primary optics family.
