Sylvania 20582 – Frequently Asked Questions

1) Do I need a dimming ballast to dim this 36W CFL, or will a wall dimmer work?
Dimming comes from the ballast, not the lamp. The FT36DL/835/ECO is built for dimmable operation, but it only dims when it is driven by a dimmable fluorescent ballast wired to a compatible control. Put it on a standard instant-start or rapid-start non-dimming ballast and it will light at full output only. On a wall dimmer alone, without a dimming ballast, it will not dim and you risk damaging the lamp or ballast.
2) Can I use this 3500K lamp in the same room as my existing 4100K CFLs?
Not without a visible mismatch. At 3500K this lamp reads as a neutral, natural white, noticeably warmer than a 4100K cool white and much warmer than 5000K. In an open office or lobby the difference between adjacent fixtures is obvious. If you are spot-replacing, match the /835 code in your existing lamps; if you are relamping a whole space, changing everything to 3500K at once is the clean way to do it.
3) How much light does a 36W FT36 CFL actually put out, and is 82 CRI good enough for retail?
2900 lumens at 36 watts, with a CRI of 82. That CRI is adequate for office, corridor, hospitality, and general retail where you need merchandise and skin tones to look reasonable, but it is below the 90-plus range you would want for color-critical work like paint, fabric, or gallery display.
4) What does the FT36DL/835 part number mean when I am matching a burned-out lamp?
Read it in pieces. FT is the long twin-tube format, 36 is the wattage, DL is the Dulux L family, and 835 means 82-plus CRI at 3500K. So FT36DL/835/ECO is a 36W 2G11 twin tube at 3500K. If the old lamp reads /841 it was 4100K and /830 was 3000K, which is the one spec to check before you order a case.
5) Where does a 3500K 2900 lumen CFL make sense versus going to LED?
It makes sense when you are keeping the existing fixtures and ballasts. For offices, retail and hospitality interiors, architectural ambient coves and dimmable fixture retrofits, dropping in the 20582 at 3500K and 2900 lumens restores the original light level with no wiring or fixture work. If you are already pulling the fixture apart or replacing the ballast, that is the point to evaluate an LED conversion instead.
6) Is the Dulux L Ecologic a lower-mercury lamp for disposal purposes?
The Ecologic designation is Sylvania's environmentally engineered line within the Dulux L family. Regardless, this is a fluorescent lamp and contains mercury, so it goes to a lamp recycler rather than the dumpster in most commercial and institutional settings.
