Sylvania SYL20683 – Frequently Asked Questions

1) Will the Sylvania 20683 CFL fit a G24d-2 two-pin socket?
No. The Sylvania 20683 uses a 4-pin G24q-2 base, which only seats in a four-pin socket wired to an electronic ballast. A G24d-2 socket is the two-pin type used with magnetic preheat ballasts and has a different keyway, so the lamp will not seat or operate there. If your fixture has a two-pin socket you need a two-pin 18W CFL instead, or a socket and ballast change.
2) Can I actually dim an 18W compact fluorescent lamp like the Sylvania 20683?
The 20683 is a dimmable lamp, but the dimming has to come from the ballast, not a wall dimmer on the line side. It needs to be installed in a fixture with a dimming electronic ballast for a 4-pin G24q-2 18W lamp. Put it on a standard non-dimming CFL ballast and it runs at full output; put a line-voltage incandescent dimmer ahead of a non-dimming ballast and you risk damaging the ballast.
3) Will the Sylvania 20683 match the other CFL lamps already in my building's downlights?
Match on three things and it will blend: base, wattage, and color. The 20683 is a 4-pin G24q-2, 18W, 2700K lamp. Existing lamps marked CF18DD/E in a 2700K or /827 code are the same family and will look identical. If the other cans are running 3500K or 4100K lamps, this one will read noticeably warmer and yellower in the same ceiling, so order to whichever color the majority of the building already uses.
4) Can I use this 18W CFL in a 26W or 13W G24q fixture?
No. CFL ballasts are wattage-specific, and the G24q pin keying changes with wattage: 13W is G24q-1, 18W is G24q-2, and 26W is G24q-3. The Sylvania 20683 is the 18W G24q-2 lamp, so it physically will not seat in a 13W or 26W four-pin socket. Order by the wattage printed on the existing lamp or the ballast label.
5) Is 1150 lumens at 2700K enough to replace an incandescent downlight bulb?
At 1150 lumens, the Sylvania 20683 lands close to a 75-watt incandescent in output while drawing 18 watts, and its 2700K color temperature is the same warm white tone as incandescent, so the room will not read cooler or bluer after the swap. The limit is the socket: this is a 4-pin G24q-2 CFL for a dedicated ballasted fixture, not a screw-base replacement for an A-lamp or BR lamp.
6) What does the CF18DD/E part number on this Sylvania lamp actually mean?
It breaks down as the lamp type and the socket. CF18 is an 18-watt compact fluorescent, DD is the double biax (double twin tube) shape, and the /E means it is the four-pin electronic ballast version rather than the two-pin. The /827 is the color code (82 CRI, 2700K) and ECO is Sylvania's Ecologic low-mercury construction. Full ordering designation is 20683 CF18DD/E/827/ECO.
7) Should I keep replacing CFL lamps or switch the fixture to LED?
If the fixture's dimming ballast is healthy and you only need a lamp, the 20683 drops straight in at 18W and 1150 lumens with no rewiring, which is the fastest fix for an occupied space. Going LED in the same can means either a 4-pin plug-and-play tube that depends on your specific ballast, a ballast bypass, or a full retrofit kit, and your existing dimming control may need to change with it. For a one-off burnout, relamp. For a whole floor of aging ballasts, price the retrofit.
8) Is 82 CRI good enough for retail or restaurant lighting?
82 CRI is the standard commercial grade for fluorescent sources and is adequate for office, retail sales floors, and hospitality ambient light. Paired with the 2700K warm tone of the 20683, skin tones and wood finishes read naturally. Where color judgment is the point of the room, a gallery, a paint or fabric display, a clinical exam area, buyers typically spec 90 plus CRI instead.
9) Do compact fluorescent lamps like this one contain mercury, and how do we dispose of them?
All fluorescent lamps, including this 18W compact fluorescent, contain a small amount of mercury. Sylvania's Ecologic designation on the 20683 identifies its reduced-mercury construction. Spent lamps are still handled as universal waste at most facilities, which means boxing them for a lamp recycler rather than the dumpster. Property managers and institutional buyers should follow their state's universal waste rule.
