Thanks alot. So the whole point is to create background lightning by using flash, but at the same time, the exposure time should be longer than with usual photo taken with flash. I'll try it when I find some space for such "nixie photographing chamber".

It is the link (this one http://www.mif.pg.gda.pl/homepages/jasiu/oldtr/OTL/index.html <http://www.google.com/url?q=http%3A%2F%2Fwww.mif.pg.gda.pl%2Fhomepages%2Fjasiu%2Foldtr%2FOTL%2Findex.html&sa=D&sntz=1&usg=AFQjCNEU9MUkoVKbnh6ygv0DP7SvaA4Qog>) about LC-2 tubes existing in commercial products. As I was trying to google more about LC-2 nixie, I was finding photos & info about the tube made by PIE (Przemysłowy Instytut Elektroniki). However, when searching for the Dolam version of LC-2, I couldn't find anything more than posts on forums claiming it existed - until I found this one photo in the very link I posted myself: Why was I searching for it? I've purchased 4 LC-2s made by Dolam yesterday. I was very happy to buy 4 rare tubes and was about to walk away from that place, but then something suspicious happened: I've found two more 10 minutes later. What are the chances of buying same type of rare tube from two different people within 10 minutes? These ones are red paint coated - something I've never seen on Polish nixies. So far, red paint was only mentioned as a possible version of LC-531. This might be homemade or for testing purposes, though - paint is spread unevenly, it creates a thick layer and it was spread over the white text. Red paint doesn't make much sense, as these tubes look mercury-free (no blue haze). I suppose this was a test during early nixie production in Poland in case they really decided to paint their tubes. What is the difference between LC-2s made before and post name change? PIE has anode mesh made with squares, Dolam used same hexagonal mesh as in LC-511, LC-513, LC-513A and LC-516. At first I thought that this is some kind of reprint or something, but the placement of decimal point is exactly the same as in PIE LC-2. So Dolam LC-2 is kind of an evolutionary link between early PIE prototypes and commonly known Dolam tubes. If you have any other photos of LC-2 made by Dolam, please post them here or message me with a link to them. I'd like to explain one thing: PIE invented LC-1 and LC-2 in 1963 (or 1964), and in 1965 PIE was renamed to Dolam. So it is basically the same company, if we can speak about something resembling a company under communist regime. Dolam using a test product from PIE times leads my mind to one thought - there might be a PIE marked LC-7 or a Dolam marked LC-1 somewhere. I'll post photos of my tubes in few days, when I find some time (and some better place for taking photographs). -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
