Treehugger reports on a 13W LED bulb as replacement for incancdescents.
It's interesting that it so much more efficient than an incandescent (which wastes most energy as heat) but has a fan inside of it to reduce heat.
They also tout other features of LED long life bulb, less mercury than cfl, etc.
But cost cost cost cost cost?
How many watts hours of solar electricity could you buy for the cost of this bulb?
