Sylvania 20881 – Frequently Asked Questions

1) Will the Sylvania 20881 CFL fit a fixture that takes a GX24q-2 or GX24q-4 socket?
No. The Sylvania 20881 uses a GX24q-3 four-pin base, and the keying on the GX24q series changes with wattage, so a q-2 or q-4 socket will not accept it. GX24q-3 is the 26-watt keying, which matches this lamp's 26W rating. If your socket is keyed q-2 (18W) or q-4 (42W), you need the lamp for that wattage instead.
2) Can I put this 26W triple-tube CFL in a socket that currently has a two-pin plug-in lamp?
No. The 20881 is a 4-pin GX24q-3 lamp, which runs on an electronic ballast rather than the integral starter found in two-pin plug-in lamps. Two-pin and four-pin bases are not interchangeable, and the socket itself differs. For a two-pin fixture you need a GX24d (or G24d) two-pin lamp.
3) Will a 3500K CFL match the lamps already in the rest of my building?
Only if those lamps are also 3500K. The 20881 is a 3500K neutral white, which sits between the warmer 2700K/3000K look and the cooler 4100K often used in offices and corridors. In a space where some fixtures get relamped and others don't, mixing 3500K with 4100K is visible side by side. Check the color code on the lamps you're keeping: the 835 in CF26DT/E/IN/835/ECO means 82 CRI at 3500K.
4) How much light does a 26W triple-tube CFL actually put out, and what incandescent does it replace?
The 20881 delivers 1746 to 1800 lumens at 26 watts, which puts it in the same output range as a 100-watt incandescent while drawing roughly a quarter of the power. That makes it a common choice for recessed downlights and commercial fixtures where the original source was an incandescent or an older, less efficient fluorescent.
5) Does this CFL hold its light output in a cold stairwell or an enclosed downlight can?
Amalgam construction is the reason to pick this one for those spots. The 20881 is a T4 triple U-tube amalgam lamp, and amalgam dosing keeps light output more consistent across a wider range of operating temperatures than a standard mercury-dosed CFL, which drops off in cold air and in hot enclosed cans.
6) What exact part number do I order for the Sylvania CF26DT/E/IN/835/ECO?
Order Sylvania item 20881. The full lamp designation is CF26DT/E/IN/835/ECO, part of the Dulux T/E/IN Ecologic line: CF26 for 26 watts, DT for the triple tube, /E for the four-pin electronic-ballast version, and 835 for 82 CRI at 3500K.
7) Can I use this lamp on a dimmer?
The 20881 depends entirely on the ballast in the fixture, not on the lamp. As a 4-pin GX24q-3 /E lamp it runs on an electronic ballast, and it will only dim if that ballast is a dimming type wired to a compatible control. On a standard non-dimming instant or programmed-start ballast, it runs at full output only.
8) Is 82 CRI good enough for retail display lighting?
At 82 CRI the 20881 is an 80-series lamp, which is the normal standard for offices, corridors, and general retail sales floors. Its rare earth tri-phosphor coating gives accurate enough rendering for merchandise where color fidelity matters in a general way. For critical color work, such as apparel fitting or paint and fabric matching, buyers usually specify a 90-plus CRI source instead.
