General Electric F15T8 Natural

Special thanks to fellow LG member Icefoglights for these beauties!

Some (I'm thinking 1970's?) GE F15T8s. I had never seen a Natural in person before so these are quite interesting to me. Apparently the CCT is 3800K, not far off from CWX's 3900K. (Nevermind manufacturers claiming it's 4100K). I'm thinking these are deluxe halophosphate as they have that characteristic 60-hertz flicker much as stuff like /950 or /CWX or /DX has. They're also not that bright, another reason I'm thinking deluxe halophosphate. Can someone give me the lumens, CRI, and other specs?

These sure do look a heck of a lot nicer in the kitchen undercabinet fixture than the nasty Indonesian cool whites do, granted I run LED retrofit tubes now which are actually 2700K.

Also- can someone date this lamp?

Also- what was the original purpose of /N? Supermarket use? I remember Westinghouse had a "Supermarket White" which was somewhere in this CCT range.

I like these awesome lamps. Unfortunately these are no longer manufactured. 5 stars from me.

Keep government out of the lighting industry.

These were popular for produce and meat counters, especially good at enhancing red colors. The /MWX seems to have a more incandescent tone which was probably for non-perishable food items or general displays. Dave would probably know more on that.

I figured they were long since out of production, especially in this age of LEDisease.

Awesome find! I saw these on EBay but they wanted a way out of line price for them. Manufactured 9/82 at the Circleville, OH lamp plant.

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

These might be perfect in kitchen under cabinet lights. The only modern thing that is a nice warm tone I like is the GE "Reveal" 2600K lamps.
