Philips 14873-4 PL-S 7W/841/2P/ALTO

Philips 14873-4 PL-S 7W/841/2P/ALTO Compact Fluorescent Lamp — 7W | 5.34 in | 4100K Cool White | G23 2-Pin Base

The Philips 14873-4 PL-S 7W/841/2P/ALTO is a 7W twin-tube compact fluorescent lamp with a G23 2-pin base, producing 4100K Cool White light with a color rendering index (CRI) of 82 and a rated average life of 10,000 hours. It is a plug-in lamp, not a screw-in bulb: it needs a fixture with a compatible ballast.

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 2-pin lamp has a starter built into its base and is made for a magnetic (preheat) ballast. A 4-pin lamp has no built-in starter and is made for an electronic ballast, and some electronic ballasts can dim it. The two types are not interchangeable, so match the base and pin count to your fixture.

4100K – Cool white - a crisp, clean light common in offices and workplaces.
