Our take on the Sylvania 20673 CF26DD/E/835/ECO 26W Compact Fluorescent Bulb 4 Pin 3500K G24Q-3

The Sylvania CF26DD/E/835/ECO is a 26-watt double twin tube compact fluorescent lamp with a 4-pin G24Q-3 base. It produces 1,710 lumens at 3500K, a neutral white light, and is rated for 12,000 hours. The 4-pin base runs on a separate electronic ballast, so it is a replacement lamp for commercial and recessed fixtures rather than a plug-in bulb. It suits anyone replacing a burned-out lamp in a compatible fixture; the main trade-off is that it needs the correct ballast and cannot be dimmed on standard setups.
