Compact fluorescent lamp for general lighting

The SYLVANIA 20587-FT18DL/830/ECO is an 18 W compact fluorescent bulb with a 2G11 four-pin base. It delivers 1200 lumens at a 3000 K colour temperature and a colour rendering index of 82. The lamp is suited to residential and commercial fixtures that accept single-tube CFLs.

Low heat output and efficient power use

Fluorescent technology converts a higher share of input power into visible light, so the bulb runs cooler than an equivalent incandescent source. It consumes 40 to 70 percent less energy while providing five to eight times more lumens per watt. The 18 W rating keeps circuit loading modest in typical installations.

Durable four-pin base simplifies replacement

The 2G11 base locks securely into compatible sockets, reducing the risk of loose connections during relamping. Rated life of 12000 hours means up to ten times fewer change-outs compared with standard incandescent bulbs. White finish maintains consistent colour appearance throughout the rated lifespan.

Questions about this item

How do I install the 2G11 4-pin base correctly?

Align the four pins with the matching sockets in the 2G11 holder and push straight in until the bulb seats firmly; forcing it at an angle bends the pins and prevents contact.

What maintenance or replacement will this 18 W CFL need later?

The lamp is rated for 12000 hours; after that point replace the whole bulb because the integrated ballast and tube cannot be serviced separately.

What limit appears first during sustained use of this 3000 K fluorescent bulb?

Lumen output declines gradually over the 12000-hour rated life, so reduced brightness is the first noticeable limit in continuous operation.
