LED PIR replace or not bother?

Kim_kim

My PIR LED 10 watt (I think it’s 10 watts ish) has stopped working & is on 24/7.
Am I right I’m working out this is so cheap to run it’s costing a couple of pound a year? 

If so I may as well leave it as replacing it with a new properly working one will cost more than the running of this one.

Maybe more like £13 a year for 15p per unit electricity

Probably worth a swap then.  Thank you.

Hi KK.

How is it wired? Do you not have a switch inside your house to operate it?

If you find it's supplied with a permanent live - for the PIR control - and the switch is used for an 'override', then it should be easy to disconnect the 'perm' and wire the switch to this so you have full manual control over it. Ergo only turn it on at night when you need to.

I don’t have a switch inside & the PIR is supposed to control it.
I don’t want a switch inside really, I want it to work automatically as a PIR. 

It’s a security light to come on if someone comes up the open side of my semi.

That's fair enough.

Most PIR lights also have an override switch inside so it can also be turned on whenever you want, and that could have been a part-solution.

You don't tho'.

Many PIRs will latch ON if the mains is interrupted a few times in quick succession, usually by a switch inside.  Reset is to switch off/remove mains for a short while and re-apply.

Have you switched off the supply to this luminaire and re-applied the mains after a suitable 30-60 second period, in case such an 'always on' setting has been invoked accidentally?

I'd want any outside light to have an on/off isolating switch for safety/maintenance purposes.

I agree with Rodders - its probably that there's been a momentary cut to the local electricity supply that's triggered the light to stay on.

Yeah, my back LED PIR floodlight is set up like that, an overide switch so I can just turn it on.
But the one I’m asking about is only a side walkway down the side of the house.

Now you mention it, I’ve had (or rather the whole village has had), a few power cuts lately.

So let me get this straight.  It’s happened because of a powercut & the fix is to cut the power again?
I have had a couple, why didn’t one of the later ones work?
