Huh? "series parallel circuit"? I'm not sure we are talking about the same thing. Julia said hers were wired in parallel. In other words, if one bulb burns out (becomes an open circuit due to a broken filament), the other bulbs still are on. If it were wired in series, a burned out bulb takes the whole string down. The problem with wiring them in parallel is that you need a transformer and the main feed parallel wires have to be able to handle a lot more current. So the parallel ones are more expensive. Most people are familiar with the series ones, but I have seen ones labeled "parallel" for sale, and from Julia's description, hers must be in parallel, since she said they only all go out if a bulb is physically removed from the socket. > shocked in any case, not an iota safer than the standard series style > lights. If pulling the bulb out shorts the power supply then you would only get shocked if you managed to stick your finger in an UNSHORT the electrodes. > The only advantage is that you do not lose *all* the lights. I don't think that is what she was talking about. Perhaps Julia can clarify, but from her description, I believe that if a light bulb burns out but is left in the socket, you do not lose ANY OTHER LIGHTS. > I have seen a design where alternate lamps go out when one lamp burns > out, rather than 25 or 50 contiguous lamps, but they are a bit more > expensive because more wire is needed. Yes, me too. But again, I don't think that is what Julia was talking about. -- "Erik Reuter" <[EMAIL PROTECTED]> http://www.erikreuter.net/ _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
