[QUOTE="Richard-the-Ninth, post: 443513, member: 23472"] Only thing I am wondering about is back emf from the relay, it may "fry" the pir (all be it slowly) I would also ask why are you doing this, since all the components you are buying will cost more than you will save in electricity by dimming them. The other (and cheaper) option would be: LED lamps 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 To have the odd numbered lamps to come on at dusk and the even numbered lamps to come on with the pir. [/QUOTE]
