Vintage GE F20T12's

Vintage GE F20T12's


I got four vintage General Electric F20T12 lamps from a viewer of my Youtube channel. These lamps came off of the USS Salem battleship. They had converted their 2 foot fixtures to F17T8 with instant start (boring) electronic ballasts. He also sent me a few of the old preheat chokes. The color on these is "white." All four lamps look like they have never been used. All four lamps are inside etch. The color looks like a modern 3500K lamp. Any help on the manufacture date would be appreciated.

Impessive find!

A couple years ago, when I toured the USS Lexington in Corpus Christi, TX, I noticed a few lights with their covers removed seem to have vintage or near vintage lamps in them. One in particular had at least one Norelco lamp in it.
