westinghouse datecode decoding and logo questions « on: June 15, 2010, 07:27:21 PM » Author: toomanybulbs
how does one decode the date on old westinghouse fluorescent tubes?
these are old f42 slimlines with black bakelite ends.
and when did the logo change from the underlined w to the one with the dots on the points?
