The GoodBulb 500W R40 Rough Service Flood Light Bulb delivers powerful illumination and rugged performance in the most demanding conditions. Built for swimming pools, industrial applications, and high-impact environments, this clear-finish reflector lamp features a robust C-9/5 filament and a wide flood beam for expansive light coverage. Operating at 130 volts, this lamp is designed for open-rated fixtures where consistent brightness, vibration resistance, and longevity are required.

With a 4,000-hour rated life and clear reflector glass, this lamp is a high-output solution for specialized non-recessed applications.

Why Rough Service & Flood Beam?
Rough service construction reinforces the filament to withstand vibration, making it ideal for industrial and mobile lighting. The flood beam delivers wide, even illumination for large open areas—essential for work environments and poolside visibility.

✔ Not for Recessed Cans – Must be used in open fixtures for safety and ventilation.

HID-Like Performance – But Consider an LED Upgrade
While this R40 halogen flood lamp excels in high-output environments, today’s LED reflector lamps offer superior efficiency, lifespan, and environmental benefits.

Why Upgrade to LED?
✔ Up to 80% Energy Savings – Reduce operating costs with efficient LED retrofits.
✔ Up to 25,000+ Hour Life – LEDs last far longer than incandescent or halogen options.
