are these ac dc or both?

These incandescent bulbs will operate on 12V AC (rms) or DC.

what size adapter would I need to light all ten of these bulbs at once?

This question is a bit vague (adapter? what type of connection, series or parallel?). These bulbs are rated at 12V and .2A. If you plan to connect 10 of them in parallel, the total current draw would be 2.0A. In this type of arrangement, any power supply/source would need to provide 12V and a minimum of 2.0A, though a higher current capacity would be better for reliability.

Hard to find

Bought these to use in my 1950’s Marx model train locomotive as well as for decorative lights around track layout. I hadn’t been able to find anything like these for years so am glad these are available on Amazon. They have all fit well and worked fine. They aren’t super bright but just right for my needs.

10 #1446 bulbs for a very very reasonable price

Needed #1446 bulbs and these are #1446 bulbs, and they light up when asked to. I have extra bulbs to replace as needed, AND without breaking the bank.
