Product Description
A high-output A21 LED built for commercial and residential fixtures needing 125W-incandescent-equivalent light output across a universal voltage range. The A21-16.5-E26-840-ND delivers 2,250 lumens of neutral 4000K light, balanced between warm and cool for general-purpose use at 16.5W input, with a 25,000-hour rated lifespan (longer than the standard A21-16 series) and operation on any line voltage from 120V through 277V.
The universal-voltage capability and longer lifespan make this the workhorse choice for commercial buildings, multi-tenant spaces, and any installation where 277V power is available alongside 120V branch circuits. Frosted lens, durable plastic construction, suitable for enclosed and open fixtures in dry or damp indoor environments.
