Sylvania 21272 – Frequently Asked Questions

1) What base does the Sylvania Dulux Double Ecologic CFL use, and will it fit my existing socket?
The Dulux Double Ecologic lamp uses a G24d-3 base, which is the 2-pin keyed base used in magnetically ballasted hardwired CFL fixtures. Two-pin bases are keyed by wattage group, so the lamp only seats in a socket cut for that pin spacing. If your fixture has a 4-pin G24q socket (electronic ballast), this lamp will not seat and you need the 4-pin version instead.
2) Which wattages and color temperatures does the Sylvania Dulux Double Ecologic come in?
Four combinations: 9W in 2700K Warm White, 9W in 4100K Cool White, 18W in 4100K Cool White, and 26W in 4100K Cool White. The manufacturer numbers are 21272, 21270, 21111 and 21115 respectively. Only the 9W is offered in warm white, so if you are matching a warm-toned residential or hospitality space at higher output, the cool white is what the family gives you.
3) Can I use a 26W Dulux Double in a fixture that currently has a 9W or 18W lamp?
No. Two-pin CFLs run off the fixture's ballast, and the ballast is wattage-specific, so a 26W lamp will not operate correctly on a 9W or 18W ballast. The G24d base is also keyed differently across wattage groups. Match the replacement to the wattage printed on the old lamp or the ballast label: 9W, 18W or 26W.
4) How much light does the 26W Dulux Double put out?
1710 lumens at 26W, 4100K. That is the output a commercial downlight or sconce designed around a 26W twin-tube CFL is engineered for, so it drops straight into those fixtures without a change in light level.
5) Is 82 CRI good enough for retail and office spaces?
82 CRI is the standard commercial fluorescent color rendering level and is what most office, retail and institutional specs call for. Every wattage and color temperature in the Dulux Double Ecologic family holds the same 82 CRI, so relamping a mixed building with different wattages will not shift color rendering from fixture to fixture.
6) How long do these Sylvania twin-tube CFLs last, and how many come in a case?
Average rated life is 10,000 hours, and the lamps ship 50 per case. For a property manager relamping a building, one case covers 50 sockets, and at 10,000 hours a fixture running roughly 12 hours a day is on a multi-year replacement cycle.
7) Should I pick 2700K or 4100K for my building?
2700K Warm White reads like incandescent and suits residential units, lobbies and hospitality spaces; it is offered in the 9W Dulux Double. 4100K Cool White is the neutral-white commercial tone for offices, corridors, retail and back-of-house, and it covers 9W, 18W and 26W. Mixing the two on the same corridor is visible, so standardize per area.
8) What kind of lamp is the Dulux Double Ecologic, physically?
It is a T4 double-tube compact fluorescent, meaning two slim 1/2-inch-diameter tubes folded side by side off a single plastic base. That compact envelope is what lets it fit recessed downlight cans and wall sconce housings built for twin-tube CFLs rather than a straight linear tube.
