LED's have made incredible leaps in the past year or two, going from
an efficiency of around 40 lumens/watt to 100 lumens/watt or more for
devices that can be readily bought for just a few dollars. When you
see a flashlight not much bigger than your thumb using one of these
things light up a room brighter than a clunky 3D Maglight it is clear
that the days of the incandescent lamp are numbered.
