CFL's last 8,000 - 15,000 hours. Incandescent's last 750 - 1,000 hours.
So what? With the stock I've been building up I hopefully won't have to buy another light bulb for 4-5 years. At that point I'll have to see what's available on the market. Until then I'll keep stockpiling the incandescent bulbs when I can find them.
