The Norman Lamps PFA-TS150A is a 150W, 130V A21 incandescent light bulb engineered for demanding commercial and industrial environments where glass containment is a safety requirement. The bulb is coated with Norman's proprietary TUFF-COAT shatter containment system using PFA (perfluoroalkoxy) polymer — the same material known commercially as Teflon — applied directly to the glass envelope. This exclusive high-temperature coating encapsulates the bulb so that if breakage occurs due to impact, thermal shock, or end-of-life failure, glass fragments are held together and prevented from dispersing into surrounding areas.

The 130V filament design provides enhanced filament durability and extends rated service life when operated on standard 120V circuits. With an 8,000-hour average rated life, this A21 incandescent bulb delivers significantly longer service intervals than standard rough-service incandescent alternatives, reducing maintenance frequency in hard-to-reach or high-traffic installations. The frosted glass finish diffuses light output for broad, even illumination across a wide area without harsh glare or hot spots.

As an incandescent light source, this bulb produces warm light at approximately 2700K with a CRI of 100, rendering colors naturally and accurately. The PFA TUFF-COAT coating is optically clear by design, so it does not alter the bulb's light output, color temperature, or color rendering relative to an uncoated equivalent. The bulb is fully dimmable with standard incandescent-compatible dimmer controls.

The E26 medium screw base ensures broad compatibility with standard lamp sockets across commercial and industrial fixtures. At 5.40 inches in overall length and 2.62 inches in diameter, the A21 form factor is well suited for open fixtures, vapor-tight enclosures, task lighting applications, and other installations requiring a larger-bodied incandescent bulb with a standard medium base.

The PFA TUFF-COAT shatter containment coating is aligned with FDA Food Code guidelines and HACCP protocols, making this incandescent bulb appropriate for use in food service, food processing, pharmaceutical manufacturing, hospitality, healthcare, and other regulated environments where exposed food, pharmaceuticals, or sensitive materials are present and glass contamination poses a safety or compliance risk. Norman Lamps operates a dedicated lamp coating facility to produce shatter-protected lamps across a wide range of incandescent, halogen, fluorescent, and HID types.
