Sylvania Dulux Single Ecologic T4 Compact Fluorescent Lamp

The Sylvania Dulux® Single Ecologic® T4 compact fluorescent lamp family delivers reliable, energy-efficient general lighting for commercial and residential fixtures built for 2-pin plug-in CFL lamps. This family is available in two configurations to match fixture and color-preference requirements: a 7W option producing a cool 4100K white light on a G23 2-pin base, and a 13W option producing a warm 2700K white light on a GX23 2-pin base. Both versions share the same self-ballasted-style, plug-in T4 design, an 82 CRI rating for accurate color rendering, and the Ecologic engineering approach that emphasizes efficient, longer-life operation as an energy-conscious alternative to incandescent lighting. Whichever configuration is selected, the lamp is a straightforward retrofit for fixtures specified for this lamp type, combining energy savings with dependable light quality for everyday lighting applications.

Sylvania 21274 – Frequently Asked Questions

1) Do these Dulux Ecologic 2-pin CFLs need a ballast in the fixture?
Yes. These are plug-in 2-pin T4 compact fluorescent lamps, not screw-in replacements, so they only work in fixtures already built with the matching CFL ballast and a G23 or GX23 socket. There is no screw base and no integral driver, so you cannot put one into a standard medium-base lampholder.
2) Which color temperature should I use to match the rest of my building's lighting?
Pick by what is already installed. The 13W lamp is 2700K warm white, the same warm tone as incandescent, which suits apartment units, lobbies, guest rooms and hospitality spaces. The 7W lamp is 4100K cool white, a neutral office tone better matched to corridors, restrooms, back-of-house and commercial downlights. Both carry an 82 CRI, so color rendering is consistent whichever tone you standardize on. Note the two tones are tied to different wattages and bases, so you cannot get 2700K on the 7W G23 lamp.
3) Can I drop an LED lamp in place of these 2-pin CFLs instead?
Not as a straight swap without checking the fixture. These are plug-in CFLs that rely on the fixture's existing CFL ballast, so any replacement has to either be ballast-compatible or the fixture has to be rewired to line voltage. If you want to stay with what the fixture was specified for, the matching Dulux Single Ecologic lamp, 7W G23 or 13W GX23, goes straight back in with no fixture work.
4) Is 82 CRI good enough for retail or office spaces?
At 82 CRI these Dulux Ecologic T4 lamps render color accurately enough for general ambient and task lighting, offices, corridors, and residential rooms. If you are lighting merchandise, paint or artwork where color fidelity is critical, a higher-CRI source is the better call; 82 is a standard commercial-grade number, not a premium color-critical one.
5) How many Sylvania Dulux Ecologic T4 lamps come in a case?
Case quantity is 50 lamps. That is worth knowing if you are stocking an MRO crib or relamping a floor of downlights at once, since buying by the case keeps a single color temperature and base consistent across the whole run.
