The graph above from Seattle City Light shows 12 months of our household electric usage (Jun-May). Each bar is 2 months, so the first is Jun-Jul and the last is Apr-May. The lighter colored left bar is the prior years usage, and the darker colored right bar is the current year (Jun 2012-May 2013) usage. Can you guess in which 2-month period I replaced all our light bulbs with LEDs?
Nice results! What LED’s do you recommend? And did you do a break even analysis yet?
I answered you (and a few other questions I’ve received) at https://matt.simerson.net/news/2013/06/23/the-roi-on-led
