GE 39289 | 18.5W LED - 42W CFL Equal - 4 Pin - Horizontal - 2700K
"The GE LED19GX24Q-H/827 is part of the GE family of LED replacements for 4 pin CFL bulbs. These LED bulbs can directly replace the CFL bulbs if the existing ballast is electronic. No tools or upgrades required. GE's advanced optics eliminate wasted light to deliver a more targeted beam with fewer lumens. The result is a more energy efficient - longer life alternative to CFL. See the document below for complete specifications and ballast compatibility. "
