The Norman Lamps 150ARS/TF is a 150W, 130V A21 incandescent light bulb engineered for demanding environments where glass containment is a safety requirement. The bulb features Norman's proprietary TUFF-COAT shatter-resistant coating, an exclusive polymer film applied to the glass envelope that contains glass fragments if the bulb breaks due to impact, thermal shock, or end-of-life failure, preventing shards from dispersing into surrounding areas.

Rated for 8,000 life hours, this A21 incandescent bulb delivers significantly longer service life than standard rough-service incandescent alternatives. The 130V filament design provides additional durability and extends rated life when operated on standard 120V circuits. The frosted glass finish diffuses light output for broad, even illumination without harsh glare.

The E26 medium screw base ensures compatibility with standard lamp sockets across a wide range of commercial and industrial fixtures. At 5.40 inches in overall length and 2.62 inches in diameter, the A21 form factor is suited for open fixtures, vapor-tight enclosures, and task lighting applications. This incandescent bulb is fully dimmable with standard dimmer controls.

The TUFF-COAT shatter containment coating is recognized under FDA Food Code guidelines and aligns with HACCP protocols for facilities where exposed food, pharmaceuticals, or sensitive materials are present. It is well suited for food service operations, food processing facilities, pharmaceutical manufacturing environments, grocery retail, warehouses, gymnasiums, and other commercial or industrial settings where glass contamination control is required.
