This one appears to be old. Rounded endcaps and the etch is on the left side as opposed to the right side for the later square endcapped Lifelines. Anyone care to date this beauty?

Wow, incredible find from 3/61! A pre-Lifeline lamp. Lifelines were introduced later in 1961. The "Preheat Rapid Start" line was moved to below the YR__ Mo__ line on the Lifeline lamps. It was deleted by 1962.

Preheat and T-12 fluorescents forever! Down with LED's and instant start T-8 fluorescents.
