I just took this pic of the tube in my dirty outdoor fixture to show the banding. A weird insect happened to land at the same time! LOL

Nice lamp and banding.

Good quality things are awesome. Cheaply made things are not.

Thanks, can you tell me the date?
I've never seen an old GE T8 get bands like this before.
I have a case of these tubes I specifically got for my two outdoor lights.

My very first word was LIGHT!

I'm still new to decoding these things but i'm guessing April of '87 from the Bucyrus, Ohio plant. Though someone can correct me if i'm wrong.

Old lighting is, and will always be, the best lighting.

These excessive phosphor bands are very common in soviet tubes, practically every tube from 1970s to 1985~ every second tube had these bands, and it seized light output dramatically. And funny thing is that it only was appearant on 4ft tubes. I have never seen a soviet 2, 3 and 5 footer have these excessive phosphor bands, only 4 footers. Weird. In my collection I cab easily find at least 50 soviet tubes with these bands..I don't know if it was the phosphor formula that was too gloppy, or did they take the tubes from the drip station a little too soon or what caused this, but I know it really seizes the light output in some tubes.

New lighting technologies is a pity fest everywhere you look. From LEDs that last only for two months, to a never-ending global starvation of t8 fluorescent tubes.
We shall reinforce ourselves with good old full mercury t12s and HIDs made to surpass one's life, and give them all the middle finger ;

I think it's probably '77 because it has an inside etch but I could be wrong too.
btw, This tube reached EOL not long after I took this pic.
