Sodium light fixture
I have an exterior light fixture, possibly low pressure sodium
standard screw base 30w bulb, someone put in 100w standard incandesant bulbs years ago and it works fine. I wondered what would happen if I put in a cfl, would I blow the cfl circuitry. |

If an incandescent bulb fits the socket, there's no electrical problem other than whether the cfl is outdoor rated -- think there's a temperature issue w/ most (if not all, still -- I've not paid much attention to them so far so what they've done on that score I'm not sure at all). -- |

I wondered what would happen if I put in a cfl, would I blow the cfl circuitry. The voltage across the CFL's base, after voltage drop of the ballast, may cause the pulse starter for a usual HPS fixture to actuate. The pulses are something like 3-3.5 possibly 4 kilovolts. Although the CFL's impedance will probably be enough to load those pulses down to pretty much nothing, I would not count on it. I would not want to explain this to my homeowner insurance company if a fire resulted. - Don Klipstein ) |
