Westinghouse 4373900  T8 (12 Watt) Cool White (4000K) G13 (Medium BiPin) Base Dimmable LED Linear Light Bulb 43739

The direct install 12 watt linear LED replaces most T8 lamps with a compatible ballast. It's the easiest way to upgrade your existing fluorescent bulb to an energy-efficient LED. Check for ballast compatibility and follow instructions to remove the old bulb and replace with the direct install LED.

Providing brightness and color quality comparable to fluorescent bulbs, this direct install LED turns on instantly without flickering, and lasts up to 2.5 times longer. It reduces maintenance costs and provides up to 56% energy savings over linear fluorescents.

Technological advancements allow for optimized general illumination and excellent light distribution. Light is focused downwards where needed, eliminating unsightly shadows and dark spots in the light fixture. Enjoy energy-efficient illumination for everyday tasks in residential, industrial, hospitality and commercial applications.

This direct install TLED is designed with a built-in safety feature--to power off permanently and avoid unexpected damage to the bulb or fixture in case of improper installation.
