ADL Supply Expert Application & Replacement Guide
Plug-in compact fluorescent lamps like this one are used in recessed downlights, wall sconces, wall washers and other compact commercial fixtures in offices, hallways, healthcare, schools and retail spaces. Because the lamp is not self-ballasted, the fixture must contain a ballast that matches the lamp.
A 4-pin lamp has no built-in starter and is made to run on an electronic ballast, and some electronic ballasts can dim it. A 2-pin lamp of the same wattage has a different base and is not interchangeable, so match the base and pin count to your fixture.
2700K – Warm white - a soft, friendly light similar to a standard incandescent bulb.
The lamp is listed with Philips ALTO low-mercury technology at 1.4 mg of mercury.
