Season of lightsFri, 18th Dec '15, 3:15 pm::
When we moved into this house 3 years ago, I replaced most of the heavily used incandescent bulbs with compact fluorescent lamps (CFL) to reduce our electric bill. But regardless of the brand, vendor, or quality of CFL bulbs I bought, they kept going bad in 6-12 months and I ended up using incandescent bulbs in more places than I wanted. So for years now we've had a mix of incandescent and CFL lights all over the house. A few months ago I estimated that over $100/month of our electric bill was just due to the tons of bulbs (candelabra and regular), recessed lights, and halogen lights!
A small 60w bulb left on at all times will use $70/year in electricity! Replace that with an equally bright CFL and while it only uses $20/year in electricity, in my experience there's a good chance the bulb will blow out within a year. But replace that with a $2.44 LED and the cost goes down to just $10/year and the LED is guaranteed to work for at least 3 years non-stop.
Last month I started the slow and tedious process of converting every single light in our house to LED. I spent about $300 and replaced every single light except for candelabra bulbs and some fluorescent tubes. I'm waiting for a good deal (hopefully under $500) to replace all the candelabra bulbs. Since we rarely use the fluorescent tubes and plan on replacing them with recessed lights in a few years, I don't see the value in switching them over to LED right now.
Once I am done replacing the candelabra bulbs, I estimate that lighting will cost under $20/month. This means the LED lights will pay for themselves in a year! After that we save $1000/year in electric bills, have a much brighter house, and I rarely have to change bulbs again. Next year I plan on buying a prelit LED Christmas Tree too. I love living in the future!
