Cost saving ... a big deal as electricity gets more and more expensive.
In an attempt to reduce the the bill ... replacing old type lights with LED and installing occupation sensors and many other things.
I have found the hager unit to be reliable (using them for about 4 years).
There are various types on the market ... PIR ... microwave and ultra sonic.
I find it gets interesting trying to figue out the time delay ... my store room for example has one fitted ... quick in and out and it is fine ... but I have located it in the worng place ... so I have to close the door other wise every time I walk pas it ... the light switches on ... if I need to scratch for something ...I end up dancing to ge tit to reactivate.
