Most homeowners waste a fortune on incandescent bulbs that burn through electricity and die far too quickly. The Xtricity T2 Spiral CFLs change that math by delivering a bright 1600 lumens while pulling only 23 watts of power. I found these to be a massive upgrade for any standard E26 medium base fixture, whether you are brightening a kitchen or a desk lamp.

Your garage workbench feels dim and uninviting until you swap out those old, flickering tubes for this LEDVANCE Sylvania daylight replacement.
