Bulbtown dot com has commen incandescents for 50 cents each.
I bought several years supply.
Also a dozen 'appliance' bulbs for range and fridge.
And some S11 profile E17 base 10watt incandescents for hobby (Keystone
stereocard viewer).

I wonder if there are going to be exemptions for specialty bulbs?
Let's say slide projector 500 watts lamps?
There isn't going to be LED and CFL for those old timers.
And ditto for those teeny size 49 for Philco radio dials?
Well, they're incandescents!
