Outdoor light on 24/7 (photosensor + movement sensor)

[tom foster]

We have an outdoor light that was fitted by the previous owners (so we have no instructions for it). The bulb recently blew, but when I replaced it, the light now stays on all the time. It's one of those lights that has both a photosensor and a movement sensor, so it should only come on when it's dark, and then only when activated by movement. I've checked the settings, but nothing seems to make any difference. Is it likely that when the bulb blew, the photosensor got fried?! If anyone has come across a problem like the before, I'd be grateful to hear any suggestions

Often if it's a cheaper type PIR light they need replacing if the adjustments don't work, someitmes the adjusting grub screw works loose from what it's supposed to adjust.

You might find the link i've attached useful if you're thinking of renewing it -

It's an easier enough job to take on providing you can safely isolate the lamp and it's switch correctly

If the photosensor is one of the bayonet jobbies, just unplug it and see if the light goes out. If it does, get a new photosensor.

Otherwise it might be the PIR.
