Sylvania 20586 – Frequently Asked Questions

1) Will the Sylvania 20586 fit a 2G11 four-pin twin-tube fixture?
Yes. The Sylvania 20586 Dulux L Ecologic lamp uses a 2G11 base, the four-pin end base found on twin-tube compact fluorescent fixtures. If the socket in your fixture is 2G11 and the lamp length matches what came out, this drops straight in. Check the base marking on the old lamp first; a 2G11 lamp will not seat in a G24q or GX24q socket, which are the other common CFL bases.
2) Is 4100K the right color temperature to match the other lamps in my office building?
4100K is cool white, the most common commercial office and corridor color. If the lamps already in your fixtures are marked 841 or 4100K, the 20586 matches them. If your building is on 3500K (835) or 5000K (850), this lamp will read noticeably cooler or warmer next to them, so standardize on one number across a floor rather than mixing.
3) Do I need a special ballast to run this 40W twin-tube CFL?
The 20586 is a 40W twin-tube fluorescent lamp and, like all fluorescents, it runs on a ballast, not on line voltage directly. It has to be matched to a ballast rated for a 40W 2G11 twin-tube lamp. Swapping a different wattage twin-tube lamp into the same fixture will either underdrive it or shorten lamp life, so keep the wattage the same as what the fixture was built for.
4) What Sylvania order code matches the FT40DL/841/RS/ECO lamp?
FT40DL/841/RS/ECO is the Sylvania product designation, and it is ordered as item 20586. The 841 in the code tells you the color: 82 CRI at 4100K.
5) How much light does the Sylvania 20586 put out, and is it enough for task lighting?
3150 lumens from a single 40W twin-tube. That is high lumen density for a lamp this size, which is why the twin-tube T5 format gets used in compact wall sconces, indirect pendants, and task fixtures where a full-length linear tube will not fit. For desk-level task work and retail display, the 82 CRI at 4100K renders color accurately enough for general commercial use.
6) Is 82 CRI good enough for retail or healthcare spaces?
82 CRI puts the 20586 in the standard commercial band, fine for offices, classrooms, corridors, and general retail sales floors. Where color judgment matters, such as paint, fabric, cosmetics, or clinical exam areas, specifiers typically call for 90 CRI or better, and this lamp will not meet that spec.
7) Can I replace a 40W twin-tube CFL with an LED instead?
Not without addressing the ballast. The 20586 is a ballast-driven 2G11 twin-tube fluorescent, and an LED replacement either has to be ballast-compatible or the fixture has to be rewired to line voltage. If you are maintaining existing 2G11 fixtures and want no electrical work, staying with the 40W fluorescent lamp is the one-for-one swap at 3150 lumens.
