Was at my LED bulb spot, Home Depot, and saw three packs of my go to Philips BR30 light bulbs for about $18 per pack. It’s amazing how the cost of LED’s has plummeted. I picked up twelve bulbs to start replacing burnt bulbs, as well as some of the working incandescent bulbs, in the front hallway. This leaves about four ceiling bulbs on the first floor that aren’t LED. Once I change those out, I think there are eight on the first level, and about four bulbs on the second level that are incandescent.
Changing out these twelve bulbs this week lowers our energy use to operate the bulbs from 2,925w to 108w. For my $80 investment in twelve new bulbs we’ll save $1,848 over the next 22 years.
