Anyway, my outside lights are recessed cans in my soffits, I have a total of 9 cans that had incandescent bulbs in them totaling 430 Watts. I now have changed them all to LEDS with a total of 61 watts. The old bulbs would last 10 months or so, my new LED are "supposed to last" 23 years.

So I,ve already figured out the daily average per year for outside lights in houston being operated dusk till dawn is 11 hours a day.
430 watt x 11 hours/day x 365 days =1726.45 kwh @ 10 cents p/kwh comes to $172 per year to operate my outside lights.
Now with the same math using the usage of the LEDs...come to $24.49 per year. Now take into consideration I just spent about $100 for the LED bulbs, and you can see there is a quick payback in about 10 months.
