Features

Crystal Clear Hard Glass Envelope

Soda-lime glass is used, which offers maximum clarity and means our bulbs aren't cloudy like other bulbs. Soda-lime glass also allows for a high degree of thickness control, while minimizing ring molds. Weather-resistant hard glass stands up to rain, sleet, snow, physical, impact, and thermal shock.

91+% Krypton fill-gas

Krypton burns brighter and cooler than Argon.

Rugged C9 Filament & Design

The toughest, most rugged tungsten filaments, designed to withstand physical shock and vibration that would shatter ordinary filaments is used. They're supported at nine different points and designed to project optimum beam pattern and thus eliminate the center dead spot.

Special Lead Wire Supports

Two additional supports add strength to the filament mount and assure proper alignment of the lead wires and the spring steel arbor.

Spring Steel Arbor

Sturdy spring steel arbor provides maximum resilience to withstand bulb-killing shock and vibration.

2 Wrapped Lead Wires

Both lead wires are individually wrapped in protective fiberglass sleeves to prevent "arcing".

Built-In Reflector Disk

Specially designed mica reflector disk, held securely in place by sturdy wire braces, redirects otherwise lost light and protects base and socket from intense bulb heat. The polished aluminum reflector disk redirects light and protects the base from the intense heat

Nickel-Plated Brass Base

The mogul prefocus nickel-plated brass base assures positive contact and automatically positions the filament for maximum visibility. And it won't corrode or "freeze" in the socket, even after thousands of hours of use.

5,500-hour life.

Long lamp life saves on maintenance and replacement costs and reduces bulb-changing operations at precarious heights.
