Stand-alone PIRs

Buy the combined units and throw the light away...

Dunno but I bought a load from B&Q a few weeks ago for £2 each. Don't know if they have any left now though....

Ben.

I just bought one from B&Q and it cost me £12.95. A combined flood and PIR cost me £7.95!

ISTR they had PIRs in Wilko a while ago for about a fiver.

Well, they probably both cost only a couple of quid to make. You pay what the market will bear, which is usually unrelated to the manfacturing cost (except it has to be higher).

The standalone one does have a relay in it. The one integral with the light probably doesn't.

The standalone one is likely to be used in better planned and more expensive installations which will bear the extra cost. The one integral with the light is at the cheapest end of the DIY market where price it key.

Yes - there is a difference between the two that I have bought. The stand-alone it will operate several lights and also can be adjusted for time delay and 'dusk' sensitivity. The combined version will only operate that one light and is set for one minute with no light sensitivity adjustment. Still a big difference in price, however, bearing in mind that the combined PIR comes with a bloody great floodlight, mounting bracket, and a 500w bulb!
