Neon lamps need a current limiting resistor, something like 47k or so, but not a transformer. Some of the screw base neons have the resistor That's the case with the teenytiny neon night-lights that are commonly built into clock radios and things. They sell those at Radio Shack. Bought a two-pack there last year. The large neon tube signs need a ballast in order to kick start the tube...similar to fluorecent lights. -- Sven Weil New York City, U.S.A. |

I guess some young'uns just enjoy arguing what they don't know about... ;-) Look up the following: NE-30, NE-34, NE-40 and NE-56. At three watts on an edison base - the NE-40 is an impressive Neon bulb. (and yes it runs fine on 120VAC - in fact it'll fire at about 85V) best regards... -- randy guttery A Tender Tale - a page dedicated to those Ships and Crews so vital to the United States Silent Service: http://tendertale.com |

(and yes it runs fine on 120VAC - in fact it'll fire at about 85V) I keep forgetting about those decorative neon flicker bulbs - the ones with two closely positioned plates cut out in the shapes of crosses, stars of David, fish, women, flames, etc. Those are so delicate that one little tap can send one of those lamps into convulsions and possibly premature failure. I had a set of the flames in a menorah and every year there's one or two that just ... go out...maybe they're all too close together (about inch or two apart). Isn't there an issue with capacitance between those bulbs if they're close together that causes them to go nuts? -- Sven Weil New York City, U.S.A. |
