Lighting Supply carries nearly 100 CFLs in the 12 to 14 watt range with both types of bases.
We thought it worth calling out because our selection includes a 4100K 13 watt CFL with a medium (Edison) base that we sell for just 49 cents at the time of this writing. But only while supplies last.
This is even less than the "per bulb" price of our 8-pack of CFLs -also 13 watt CFLs, but those run at 2700K (a more traditional replacement for incandescent bulbs).
Whether you're looking for a CFL at 13 watts or much more, like 100 watts and more, Lighting Supply has an expansive selection (hundreds of CFLs) to meet your needs. Stop by, search online, and let us know if you need a hand with anything. We're always glad to help!
