The LED lamps will make there way in mass production one day.
It will all depend upon price.
I have some CFL's in my lounge which have done 12000 hrs now and still going strong. NZ$7 (US$4) each so they were a good deal.
In my workshop I prefer the normal 5 or 6 footers Triphosphor tubes. ( these last for 15000 hrs + )
Nice bright and new tubes only cost NZ$3 ea.

For our normal lamps the filament lamps are the most practical option at about NZ0.89 ea. with their usuall inefficiencies. (they go for about ±800 hrs).
As you know I'm the meterman and have quite a few meters hooked up in my house to do these surveys.
