The Norman Lamps 150ARS is a 150W A21 incandescent light bulb engineered for demanding rough service environments where standard bulbs fall short. Operating at 130V with an E26 medium screw base, it is a direct fit for standard North American sockets in industrial, commercial, and residential applications where durability is the priority. The frosted glass envelope delivers smooth, diffused light output of approximately 2480 lumens with a warm 2700K color temperature that renders colors naturally and creates comfortable, inviting illumination. At 5.40 inches in length and 2.62 inches in diameter, the A21 form factor provides a larger luminous area than standard A19 bulbs, making it well suited for floor lamps, large table lamps, pendant fixtures, workshop lighting, and any high-output general lighting application. A reinforced filament construction allows this incandescent bulb to withstand mechanical shock and vibration that would quickly shorten the life of a standard bulb, while the brass base adds corrosion resistance and ensures a reliable electrical connection. With a rated life of 8000 hours and full compatibility with standard dimmer switches, the 150ARS delivers long-lasting, controllable incandescent light in a proven A21 package. Sold individually.
