[Shop-talk] Replacement florescent bulbs F42T6

[Bob Spidell]

Makes sense. It's been a couple years, and my memory's fuzzy, but now I 
remember I had a couple bad ballasts and, since I had to replace them I 
got LED-compatible ones and installed LED tubes (T12 IIRC).

LEDs must need /something/, at least according to the ones I'm 
familiar--they're used in rectifiers--need DC current (probable at 5 or 
12V).
