Why are you pitching your CFLs for LEDs?
The CFLs are pretty energy efficient already over incandescent. The electrical cost savings going from CFLs to LEDs will be very low ... you've already had the BIG lift going from incandescent to CFL. LEDs have come down in price, but aren't cheap.
Enlighten us.
I used to preach this, but recently started replacing my cfl's with LED.
The warm up is what bothers me. If it was simply a case of cost analysis, I probably wouldn't, but LED's are just better in the very few ways a light bulb can be better.
Also, I literally just did the same exact thing as him, I had recessed br30's in my kitchen. I replaced them with LED that were rated for similar lumen output. I have 6 recessed cans. To compare them I replaced 1 of them with LED, flipped the switch, and the one LED seemed brighter than the remaining 5 cfl's combined. 2 minutes later they were about equal, but it's nice not to have to wait now.
I have candle based cfl's that suffered from the same issue. All my regular cfl's don't seem to have the warm up problem and I haven't lost one since I installed them in '08.
