A premium field-adjustable HID retrofit lamp — the modern replacement for legacy mercury vapor, metal halide, and high-pressure sodium installations. The A21-17-E26-9CCT-DIM-UNV combines field-selectable color temperature, full-range dimming, and a 5-year warranty in a single SKU that simplifies specification across mixed-CCT projects.
A dip switch inside the lamp lets installers select 3000K, 4000K, or 5000K at install — one part number covers warm, neutral, and cool requirements. Output ranges from 2,200 to 2,350 lumens depending on CCT, all at 90+ CRI. Precision die-cast aluminum heat sink, frosted polycarbonate lens, and a universal-voltage driver with 4kV surge protection make it field-ready for outdoor and demanding indoor environments.
