  1. Nice research Rob. The math bears out your conclusion that LEDs are less costly of the life of the bulbs compared to the alternatives. I wonder whether 20+ years is what one can realistically expect from an LED bulb’s lifespan. I remember expecting 10 years or so from CFLs but never saw that ever. When I would put in a new CFL, I would write the installation date on the bulb’s socket for reference. Usually I’d have a CFL last for about 2 years max. I hope LED bulbs last 20 years but I’m wary of those claims. All my LEDs have installation dates written on them.
