Philips 591800 T8 Led Tube 32W 48in Cct 2-pack Mainsfit

Product Description

The PHILIPS 591800 is a two-pack of 32-watt, 48-inch T8 CCT-selectable LED tubes designed for direct-wire (ballast-bypass) installation in existing linear fluorescent fixtures. Known as the MainsFit series, these tubes wire directly to line voltage, eliminating the ballast entirely. Removing the ballast reduces system energy consumption, lowers maintenance costs, and removes a common failure point from the fixture. The double-ended direct-wire design keeps installation straightforward and meets standard safety requirements for ballast-bypass retrofits. Suitable for both residential and commercial environments, these lamps operate reliably in cold temperatures, making them a practical choice for unheated spaces.

These LED tubes are intended as a direct replacement for existing T8 and T12 fluorescent lamps in standard 48-inch bi-pin fixtures. Typical install locations include laundry rooms, kitchens, garages, and basements in residential settings, and retail spaces, offices, parking garages, and industrial facilities in commercial applications. The CCT-selectable feature allows the installer to choose the color temperature at the time of installation, reducing the need to stock multiple SKUs for different lighting requirements across a job site.

Key Features

• Direct-wire ballast-bypass design eliminates the ballast and associated maintenance
• Replaces both T8 and T12 fluorescent tubes in standard 48-inch fixtures
• CCT selectable at time of installation for flexible color temperature matching
• Double-ended wiring design supports safe, code-compliant installation
• Contains no mercury, unlike standard fluorescent lamps
• Rated for cold-temperature operation, suitable for garages, coolers, and unheated spaces

Compatibility

Designed as a direct-wire ballast-bypass replacement for standard 48-inch bi-pin T8 and T12 fluorescent fixtures in residential and commercial applications. Ballast must be removed and fixture must be rewired for line voltage prior to installation.

Installation Notes

Installation must be performed by a qualified electrician in accordance with NEC requirements for ballast-bypass LED retrofits. Always disconnect power at the breaker before opening the fixture and rewiring. This product uses a double-ended live-wire configuration — both lamp holders carry voltage, so fixtures must be labeled accordingly after retrofit. Follow the manufacturer wiring instructions included with the product and verify fixture tombstone type compatibility before installation.
