Ideal for commercial 2 x 2 foot fixtures, Philips 34942-3 (PL-L 36W/835/4P) compact fluorescent lamps provide significantly lower operating costs thanks to their 15,000 average hours of life, which is more than double that of a standard incandescent. This 4-pin, 2G11 base CFL operates at 36 watts and emits a wonderful halogen white 3500K color temperature. Use these lamps for general-illumination ceiling luminaries in retail, hospitality, and office applications demanding higher lighting levels.
