Is it time to change over to LED light bulbs?

If you’ve been paying attention, you’ve noticed incandescent light bulbs have been disappearing from store shelves. The phasing out of traditional bulbs means we’re seeing more compact fluorescents (CFL) and, lately, more LED bulbs. Today we’re looking at the LED offerings I could find locally. I set out last week to Home Depot, Lowe’s, Target, Best Buy and Wal-Mart to see what was available as an LED replacement for a 60-watt bulb. Watt’s a lumen?
