The calculation was for 50 bulbs 5 hours a day. In my house, I leave 3 basement lights, and one shop light on all the time (hard to get to the switches). And outdoors, there are 4 lights on dawn-to dusk (say 10 hours).
So, do the math. The 4 bulbs on 24/7 are the same as 19 bulbs for 5 h ours. The 4 lights on for 10 hours a day are equivalent to another 8 bulbs in my case of 5 hours. So you see, already there are 28 of the 50 bulbs. The other 22 bulbs lncludes the 5 in the dining room fixture, 5 in the kitchen. 2 each in 2 bathrooms (4 total) and 2 in each bedroom (8 total) and there is the 50, not counting at least 6 more bulbs scattered around the house that are not on. So the 50 bulbs I used seems reasonable. With three teenagers, all the lights are on from dusk to around midnight. About a third are 100W, about a third are 75 and about a third are 60. I stand by the average of 75W and that saves about 60W each when replaced with a 9W LED. I stand by my numbers. Bob se 8 lights alone are worth In 24 hours, that is the same as On Fri, Jul 27, 2018 at 1:37 PM, Matt Awesome via EV <ev@lists.evdl.org> wrote: > > I stand by my numbers when corrected to a house that leaves most of their > > lights on all evening and assuming averqaeg 75 Watt incandescent bulbs > > originally.. > > Which is some extreme outlier family who's electrical usage is > literally 10x the average home. > > Ya gotta think, the crossover between people who use 10x the national > average of electricity, as much energy as the rest of their entire > block, and people who drive EVs, would drive EVs, or would even care > about the monetary savings... is probably exactly zero. > > So, I'm not sure how much value there is in such an extreme off-case. > > https://www.sciencedirect.com/science/article/pii/S0306261916305360 > > This has some datasets in Table 3 for hours of lights on in 3 different > rooms. > > The mean for a living room is 7.15 with a standard deviation of 4.32. > To find someone with not even 3x that (20), you're already looking at > 1 household out of 1000.
