Even if LED only last as long as cheap incandecent, you still comes out way ahead.

Cheap bulb = $1 + (1200 hrs) (0.060 kW) ($0.20 / kWh) = $15.4
LED bulb = $2 + (1200 hrs) (0.009 kW) ($0.20 / kWh) = $4.16

Instead of going for long lasting product, may be cost-to-own criteria is better.

Well, if you live in a cold country, that math doesn't add up. If I have a 60w light bulb lit, then I spend 60w less on my heating. And.. I get light as a bonus
