I did a presentation at the Garlic and Arts Festival in Orange Massachusetts this past weekend on home energy efficiency. For it, I prepared a slide comparing light bulb costs. The title of my slide on the topic became "Congratulations LED's! You Did It!" Why? On Amazon, you can now by LED's that are so cheap that they pay themselves in about 6 months! Here is a chart that shows off all the details:
I can't speak to the TCP bulb's attributes personally so I included the Philips bulb which I love (although lamp shades that attach to the bulb don't always sit right). I have about 20 of them in my house.
I created the above chart before I new about the proposed November electrical rate increase (see previous post). If rates go up to 23 cents per kW the TCP bulbs pay for themselves in 4.7 months instead of 6.4.
