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?
The LED's are rated for 25,000 hours of usage. At 3 hours a day they should last 22.8 years!
At 11 cents/Kwh, these bulbs will cost $.90 / year to operate x 4 bulbs = $3.60.
A regular 40 W incandescent at 3 hours/day would cost $4.80. It would cost $19.20/year to operate these bulbs.
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!
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.
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.
