Product Description
The G E LIGHTING 20185 is a 40-watt T12 U-bend fluorescent lamp rated for commercial and residential lighting applications that require a compact, folded-tube configuration. Running at 4,100 Kelvin, it produces a cool white light output of 2,450 lumens with a Color Rendering Index of 82, making it well suited for overhead fixtures in offices, retail spaces, and light industrial settings. The lamp operates on a dimming ballast and carries an 18,000-hour rated life, reducing replacement frequency in high-use installations. The bulb finish is white, and the overall maximum length is 22.5 inches.
This lamp is designed for U-bend fluorescent fixtures that accept T12 lamps with a 6-inch leg spacing. Typical install scenarios include 2×2 and 2×4 recessed troffers, wraparound strip fixtures, and industrial bay fixtures configured for U-type lamps. The 40-watt draw and cool white color temperature make it a common specification in commercial drop-ceiling grids. Dimming capability requires a compatible dimming ballast already installed in the fixture. The lamp is individually bar coded and sold in a box of 12 units per package.
