    PIR security light works in reverse

    I've just changed the bulb in an outdoor PIR security floodlight (to LED). But the light stays on by default, and turns off when I go outside. I don't think there is a control to "reverse" its mode of operation.

    Strange things happen with two PIRs in parallel

    I needed to illuminate our dark side walk at the house. I have used two PIRs wired in parallel which switch four LED lights. The idea is no matter which side of the walk you start at, you'll always set one PIR off and have light. This works, but randomly the MCB of the circuit triggers. I...
