Compact fluorescent lamp for commercial fixtures

The SYLVANIA 20118 is a 25-watt compact fluorescent lamp with a 4-pin 2G11 base designed for long luminaires in offices, retail spaces and institutional settings. It delivers 2500 lumens at a 4100K colour temperature with an 82 CRI rating.

Thermals noise and power draw in normal use

Operating at 25 watts, the lamp runs cooler than equivalent linear fluorescent tubes while maintaining steady output. The electronic ballast compatible design eliminates audible hum and reduces flicker during start-up and continuous operation.

Ecologic High Efficiency

The Ecologic High Efficiency designation indicates reduced mercury content and compliance with environmental regulations for easier disposal. The DULUX L SUPERSAVER ECOLOGIC construction extends rated life and maintains lumen output over the service period.

Questions about this item

How do I fit the 4-pin 2G11 base into the fixture, and which step do people often miss?

Align the four pins with the socket slots, push straight in until the bulb seats firmly, then give a slight clockwise twist to lock it; the twist is the step most people skip.

What maintenance or replacement will this 25 W CFL need later?

The lamp itself is the only replaceable part; when output drops or the tube darkens after its rated life, simply swap in a new FT40DL 25 W 2G11 bulb.

What limit appears first during sustained use of this 2500 lm 4100 K tube?

Lumen depreciation is the first limit — expect light output to gradually fall below the initial 2500 lumens as the phosphor ages during continuous operation.
