Replacement Bulb for Sylvania 150A21 | 150W A21 | Soft White | Frost

Sometimes a standard light bulb just isn't enough. When you need maximum brightness for a large room or a reading nook, this replacement for the Sylvania 150A21 delivers. It pumps out a massive 1760 lumens of soft white light, banishing shadows and making everything easier to see.

It uses a slightly larger A21 glass shape to handle the heat of a 150-watt filament, but it still fits into standard medium sockets. The frosted finish is key�it diffuses that intense power so you get a room-filling glow rather than a blinding glare.
