## Description

Upgrade to the 13W 4-pin compact fluorescent bulb that offers dimmability, long life, and serious energy savings in a compact double-tube form factor. Designed exclusively for electronic and dimming ballast operation, this plug-in G24q-1 base lamp installs easily - just drop it in and dim it down. Delivering 900 initial lumens at 82 CRI, rare earth phosphors ensure white 3000K light that renders colors accurately and naturally. Whether illuminating a retail showcase, a recessed ceiling fixture, or a garden walkway, the double-tube design provides efficient photometric performance in a smaller overall footprint than single-tube alternatives. The 20,000-hour average rated life is where this cfl light bulb truly stands apart - lasting up to 20 times longer than a standard incandescent and twice as long as many conventional CFL bulbs. Mean lumen output holds at 86% throughout the lamp's life, so light output remains strong and consistent from first use to final hour. Fewer replacements means lower maintenance costs and less disruption to your space. Energy efficiency is built in at every level: this 13W lamp uses approximately one quarter of the energy of a comparable incandescent. When paired with an electronic dimming ballast, the system maximizes savings further - reducing wattage and electricity costs whenever full output isn't required. TCLP and RoHS compliant, meeting Federal non-hazardous waste criteria in most states. Available in 13W, 18W, and 26W across 2700K, 3000K, 3500K, and 4100K. A trusted 4-pin cfl compact fluorescent bulb for contractors, facility managers, and homeowners who want controllable, long-lasting light.
