Our review of the (10 Pack) Sylvania 20684 DULUX 26W double compact fluorescent lamps finds them best for homeowners and light commercial users who need reliable, energy-saving replacements for incandescent bulbs. The single biggest reason to buy is the combination of warm 2700K light and long 12,000-hour rated life, which delivers soft, useful illumination while reducing replacement frequency and energy use. In this review the lamps are evaluated for brightness, compatibility with electronic and dimming ballasts, and overall value for money.

Key Features

• 1710 lumens output: Delivers ample brightness for recessed fixtures and general-purpose lighting without harshness.
• Long life: Rated at 12,000 hours, these lamps reduce replacement frequency compared with standard incandescent options.
• G24q-3 4-pin base: Fits fixtures designed for compact fluorescent 4-pin lamps and is easy to install in compatible sockets.
• Dimming and electronic ballast compatible: Works with dimming and electronic ballasts, offering more control over light level when paired with compatible dimmers.

Who It's For

This 10-pack is aimed at homeowners updating multiple fixtures at once, property managers replacing bulbs in kitchens or common areas, and small businesses seeking an economical, long-life fluorescent solution.
