Replace outside lights with LED light bulbs with this easy to follow guide. If you hadn’t taken notice, the remaining ban on incandescent bulbs has gone into effect. There will be no new 40W or 60W incandescent bulbs produced. Retailers will only be allowed to sell out of their inventory.
This doesn’t mean you can’t use them if you already have them. They are cheaper than the alternative CFL’s and LED’s. Wait….. are they really cheaper?
Step Two
The LED's are rated for 25,000 hours of usage. At 3 hours a day they should last 22.8 years!
Step Three
At 11 cents/Kwh, these bulbs will cost $.90 / year to operate x 4 bulbs = $3.60.
Step Four
A regular 40 W incandescent at 3 hours/day would cost $4.80. It would cost $19.20/year to operate these bulbs.
Step Five
Let's assume the incandescent bulbs were free. The LED bulbs cost me $7 each or $28 for the set. Since I'm saving $15.60/year then my break-even point would be 1.8 years. That's not bad!
Step Six
Obviously the less you use the lights then the longer the break-even period would be. If you only used the lights 1 hour a day then the break-even would be 5.4 years.
Step Seven
I do have some outside lights that are 60W and I leave on about 8 hours a day so these were the first to get replaced.
