I want to show my sister some hard facts on how much a 13 watt incandescent (60 watt bulb output) would cost to run for a full 7 day week 24 hours, month, year, ect vs a regular 60 watt bulb..
are there any sites that do conversions?
I'm trying to make her a believer in cutting energy costs..
I saw a 6 pack of 60 watt equlivent 13 watt incandescents for a dam good price at Costco..
any help would be great..
thanks
