I recently purchased a 500w heat sensored security light for the rear of my house. I know it's part P work and i also know it'd [u]not[/u] recommended to wire into the lighting circuit. I'm going to get a leckie round but wanted to know how a security light is wired for my own information? It will be mounted up near the guttering and the wiring will lead into the attic. House is 10 years old and the electic wiring in the loft is neat and in excellent condition.
