That's the kind of etch my grandpa's lamps from HD looked like except his are F40T12 5000K lamps. They're new lamps too. I'll have to check the date code... I was surprised and very pleased to see they weren't alto lamps.
Hmm. This is probably the same type of lamp he has. I honestly didn't pay close attention to the etch. I was side-tracked by no green endcaps and no "Alto" marking on the lamp.
