Outdoor sensor light won't switch off

I have an outdoor light by the front door which turns on when it senses movement. The bulb went on it a while ago and since replacing it, the light doesn't automatically turn off. Do I need a bulb with a specific wattage? I don't have the original anymore.
 
Probably?

Unless you're live inadvertently flicked the switched in a certain manner to leave it switches on permanently (which is a thing)

The only switch I'm aware of is the one which turns it sensor on or completely off on the inside of the house. Is there likely to be one on the unit itself?

That should also turn it off.

Flick the switch, leave it 30s, flick it again. It may come back on but may turn off again after a short period.
 
Yes, that does turn the light off. No matter what I do with it, when I switch it to the on position (bulb used to go off after a while) it now stays on.

I'd try the following then:

Flick it off and leave it off for a few minutes, then turn it back on - see what happens

Flick it off, on, then off again in quick succession - then flick it back on and see what happens

If none of that works you could flick off the fuse it's connected to in the fuse box, presumably one of the light circuits.

Failing that, it might be the bulb? Or, the sensitivity is set too high/low maybe
 
our (very old as far as i can tell) sensor died a while back and it would do stuff like that. In fact half the time it wouldn't turn off at all.

Wattage wise in theory there is a bulb max on a sensor, but unless you've put something crazy in there its unlikely to be that.
 
buy a new light fitting with a built in LED light and PIR

the bulb you will be using will be consuming 100 times the power of an LED.

so the £20 spent on a new fitting will pay for itself.
 
I've tried normal bulbs and LED bulbs in it, same result. It's at the front of the house next to the door so I want something that looks decent.
 
Your existing lamp should have adjustments on it. You usually have:-

Ambient light - how dark it needs to be.
Time - how long it stays on.
Sensitivity - how much movement is required to trigger it.
 
Cheers there's one for £12 that will do the job. Going to look at mine tonight and see if there's any adjustment on it at all.
 
i had the same issue on the PIR over my garage, ended up just switching the thing off. i have one in the back garden too, that started playing silly buggers too, replaced the bulb etc, then it just stopped working. it's about 15' up so i can't get to it sensibly so that's been turned off too, lol. bit of a bugger sorting the bins in the winter night, been thinking of getting an electrician in to wire up a couple LEDs w/ just an on/off switch in the garage, don't really see the need for a PIR now.
 
Normally a quick on off on will keep it switched on.
After a prolonged off turning on it should come on, the sensor itself off after whatever the delay is supposed to be.

You need a decent off before turning on to avoid triggering the perm on. On mine I tend to leave it 30 mins or so, always works then.
(problem is other half turns the outside light off when meaning to turn the hall on, so she immediately turns it back on, its the quick off on that triggers the sensor to go to perm on)
 
I know latching PIRs exist but it's definitely not a standard feature on all lamps. I've had quite a few over the years and none of them has had a latching option.
 
Took it off last night, no adjustment etc, just a simple relay box and wiring to the PIR and bulb. Think I'll just replace it.
