If you don't know the date code system and the number of punches in the end caps, they would be easily mistakened to be 1960s vintage!

What month?

Why I like LEDs on top of other lighting tech?
LEDs = Upgrade 95% of the applications. (That is if you avoid eBay's LEDs).


LED brainwash? No, people uses them cuz they work well for them.

Sweet GE's. The inside etchers are the best. I still use these things. Don't look at date codes, just throw 'em in, they are a dime a dozen still fortunately.

What plant was still using inside etch F40 in '87? Reminds me of the time I found a brand new inside etch F40/SW during the 90's along with the regular outside etch usually found at the time. This was in a big box store with a constant restocking too! Wish I'd saved it but I didn't realize how cool it really was at the time.

UPDATE: I lit them. They have the long electrode leads like current GEs and very little use. Awesome lamps!

Warm white too. Superior score!

T12/ t17 there's a reason they made heavy magnetic ballasts

My guess would be 1/77 as Bucyrus was still using inside etches. Could be their cheaper lamp as opposed to Mainlighter, their premium lamp.

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

No, I found they got the newer, longer electrode leads, plus they got the 2 digit numbers stamped outside somewhere, neither were present in '77.

AWESOME!!!!!
When did the two-punch end caps start?
What is the latest T8 you're aware of with inside etch?

My very first word was LIGHT!

The 2 punch end caps came along in 1974. I know GE made inside etch F15T8s until at least the early 80s.
