I couldn’t agree more. I wonder what colors were available.

If anyone has the deep bowl for the Thorn Alpha 5 that they don't mind parting with, it would be a great help. I saved a lantern a few years ago and to my horror the engineer ripped the bowl off and it split right down the side. It would be nice to make the lantern whole again. 

@BT25 — I used it for a short period when I was 12 or so. Made troll accounts for fun (and trolled pedophiles, etc.) but haven't logged in since 2021 or so. So I very much understand your sentiments.

sounds interesting. Just for clarity, one headlight was okay and one was abnormal ?
Just as it was often the case for old Xenon-HID headlights ?

Just asking, because I finally got my first LED headlights last year, an amazing experience.

However, the chromatic aberation is high, resulting in a blue concentric border of
the light cones. Almost like the blue part of a rainbow. Which I like a lot. Still
I am wondering if this was intended or not. Chromatic correction of the lenses,
however, would be much more expensive. And it seems that a lot of cars show such an effect.

Vice versa, headlights might appear blue/purple when looking at them from exterior,
depending on the angle of sight. Just wanted to check if this was not the root cause
for the issue described above.

all the best, C.
be much more expensive

So far, when I visited a Dan Flavin fluorescent light fixture sculpture exhibit at the Norton Simon Museum in Pasadena, California, I have seen what appear to be specially reproduced fluorescent tubes that are no longer manufactured or banned in the USA that have no etches whatsoever. For example, I have seen what appears to be a genuine F40WW fluorescent tube and also some colored fluorescent tubes with no etches whatsoever. I think that the tubes were specifically manufactured in order to maintain Dan Flavin’s fluorescent light fixture sculptures and preserve their original beauty as I am pretty sure that the artist wanted to maintain the beauty of halophosphate fluorescent tubes.

I wonder if the lamp industry will become similar to the nixie tube industry, with only one or a few select people putting effort into making them for a very high price once old stock runs low. I could see someone handmaking F40T12s and selling them for $50 a piece lol. I hope not.

Interestingly, I am aware that Japan has been producing some 5000K triphosphor miniature T5 tubes

So far, I have not found any information on how they achieve energy saving. If one shows up on Yahoo Japan Auction or Mercari Japan, it would be nice for one of the collectors to use a proxy service to import one into their collection to study its spectrum throughout the warmup process to see if there are any additional buffer gases present.

I would be very interested in one or two Westinghouse RMA 100 watt MV fixtures in good shape with all components if working when removed. I live in MD

@HomeBrewLamps - Now you know why I'm not on any social media!
It came about after I saw any use for it...one of the benefits of getting older is that you acquire a BS meter from years of observation and experience.
