The 60 W bulbs will indeed become more scarce as the year progresses.
They will however still produce 60 W HALOGEN bulbs that might still serve your
needs.
The smaller bulbs you mention will not be affected.
I used to buy up really cheap strings of tiny incandescent ‘Holiday’ bulbs for
workshops.
Very easy to see the filament etc.
CFL’s & LED’s are a whole ‘nother ball of wax with their Electronic Modules
that let them run nicely on 120VAC.
LED’s are low voltage DC devices and CFL’s need to be ‘Current Limited’ to
keep them from exploding.

Will I still be able to buy incandescent bulbs for batteries 'n bulbs labs
and DC circuit labs? For Pasco's CASTLE kits
http://www.pasco.com/prodCatalog/EM/EM-8624_castle-kit/index.cfm#featuresTab
students are supposed to dissect a bulb and see the continuous conductive
path through it. We use little #14 and #48 bulbs as current detectors, but
they are also supposed to play with a large 60 W bulb as well. Will I still
be able to get them for specialized purposes like physics labs, or will they
really not be sold anymore at all? Should I go buy a career's worth of
bulbs and hoard them through until retirement?
Should I care? Can students learn the same things from CFLs or LED bulbs?
Thanks,
Larry
