Here's a NEMA tag I made that somewhat approximates the type found on older GE fixtures, in case you're wondering the font I used was called Helvetica Condensed which is my best guess as to the font the GE used.
How did you get Helvectica fonts for free? I downloaded a series of fonts named "SWIS721" that appears identical to Helvectica. They didn't have one as narrow as what GE used so I had to bring it into publsher under Word Art and stretch taller and narrower. After looking at the tags Joe M. sent me, I think it's actually between our two tags.
What is the stock size for the NEMA labels? I'm thinking it would be cool to be able to print our own labels using these images and maybe build a Word template to print on some standard sized labels - you'd probably still have to cut them, but we could get pretty close to the real thing, cheaply.
I believe they are supposed to be 3" X 3", I've been planning to print some out on to labels but I could never find the 3" labels at the store. Another way I wanted to try was to find a place that makes custom bumper stickers in low quantities and have them print some NEMA tags on to bumper sticker stock.
There's a place around my area called "Fast signs", I wonder if they could do it... And yes, NEMA tags are standard in 3"X3" and 1"X1" sizes. The latter is usually only used with decorative post tops though.
