I've noticed that electronic ballasts on T12 lamps do make killer endbanding sometimes. As for these 90's era GE's, I've also had batches of them do nice endbanding on magnetic ballasts as well while other batches won't at all. But that sporadic endbanding with GE's goes all of the way back to even early mainlighters. I have some old mainlighters that refuse to endband, lol.

Nice lamp! I like this etch, I occasionally find 90s meatball etchers at the dump that still work and save them.

@don93s I hear that about the end banding. Is it the gas or amount of mercury that causes the end banding? Why is it only certain lamps that develope these unique end bands?

Cool

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

My only theory is either the mix of emitters used at the time, as the availability of ingredients on the market, how they are applied, or if phosphor coating has possible influence. I've seen the texture of the coating vary, but that could be due to what plant it was made at too.

I wish I could get a few Westinghouse tubes to do this. That would

Westinghouse is the same way. I get certain lamps that band like crazy then another batch of same size and phosphor won't band at all.

Do you have any Westys with end bands for sale? Also, I've found that preheat ballasts do some of the best end bands on lamps. I'm guessing it's because the Cathode burns from one side to the other on a gradual Pace unlike rapid start.
