I’ve seen some dodges such as light bulbs in slightly nontraditional wattages e.g. 95 watts. Since they did not previously exist, there is nothing from the past to compare their efficiency to.
I just bought a case of those 95 watters made by Sylvania.
4 bulbs for $1.
I now have at least a couple hundred 100 and 95 watters to last probably my lifetime and I’ll buy more before the years is over.
