We use a 70w Thorn son luminaire to light the front of the house and the pathway to the front door. This isn't a security measure, it's just to help folk get to the front door after dark. The luminaire has an in-built twilight sensor but is also controlled by a time switch. This time switch is set to turn the luminaire off between midnight & 05.00. Recently the lamp has sometimes not been coming on at dusk. I have fitted a new lamp and ignitor but the problem remains. I have also tried taking the time switch out of the circuit but this makes no difference. As far as I am aware the problem is, therefore, with the ballast or capacitor. Any ideas which please? Many thanks Nick.
