quote:Originally posted by nixie: I'm interested in attempting to fabricate some larger scale bulbs and wondering about electrode materials, gas pressures, and voltages.
quote:Originally posted by nixie:also, what physically happens so that NE glow bulbs get zapped with no current limiting? How could one determine ideal current for a bulb?
quote:Originally posted by nixie:is there some advantage to using nickel over steel? or perhaps nickel steel (like 308 stainless)?
quote:also, a larger glow lamp would seem to draw more current than a smaller one. would this in turn cause it to blacken the glass faster?
quote:do you think using some sort of tungsten and halogen mix could work to prevent this like in halogen incandescents? If it worked it would mean a loooooong life, I would think.
quote:also, how hot do the electrodes get? i guess that would depend on current to some extenent. solder connections probably would be inferior to welded?
quote:Originally posted by James:Swedish iron wire is the classical material used for neon lamp electrodes, but I'm not sure how this differs to ordinary pure iron - do you know Max?
