For some years I have been using a PIR light switch in my hall and on my landing to make the lights come on only when movement is detected. These things seem to have a short life. The last ones, I bought from Maplins but they lasted about two years. The components seem to give out often before the fuse blows if there's a power surge, it seems. Recently, the one on the landing and the one in the hall both went belly-up simultaneously.
So I'm looking for a source of these again - especially a type that is known to be long-lasting. Anyone know of any? £25 a piece is my limit...
Thanks
