According to my super simple ROI calculator, it shows that if you use this bulb for 5 hrs a day 365 days a year, and pay 12 cents per kWh, your ROI will be 16.6 years.

This ONLY calculates electricity savings though. Bulb replacement cost (since LEDs have crazy long life) is not included in this. At the point of ROI, the bulbs would have 29850 hours on them and the LED bulb would be at the end of its life. I'm sure you'd go through a lot of incandescents in that time.
