Heck the efficiency gains are the maybe the fourth most important reason I switched to LEDs. #3 is bragging rights of course, #2 is the instant-on vs CFLs (barely perceptible 1/10 sec until 100% brightness). #1 is the annoyance cost of having to replace a lightbulb. Almost all of my lights are either recessed in the ceiling or in annoying-to-access fixtures; not having to find a ladder or chair and balance the replacement in one hand is well worth the ~$10-20 LED bulbs cost. Amortized over their expected lifetime it's minuscule and if I move I'm taking the bulbs with me.
