I need to put some lights in a short length of passageway in the house. It has no natural light. I was considering LED's wired 'permanently on' as cheaper than using a PIR.
Any suggestions as to fittings and lamps? There are no walls I can use so it has to be ceiling.

Every watt of power used by your lighting costs over a £1 per year now
So a PIR taken off a £6.99 floodlight (LIDL,ALDI from time to time) will save you money pretty quickly. You can still use it to control LED lights for even more savings.

There's a bit of hallway in my house like that. I bought a fitting I liked, and then converted it to take a 10W 2D fluorescent with electronic ballast.
What's the standby consumption of a PIR?

Gotta be peanuts - a mA or two.

Bulk head type LED emergency lights.
Honeywell are one of the few suppliers of light switching PIRs who have readily available data sheets. The PIR on its own is around 0.25 Watts.
I investigated some of the dusk to dawn photocell switches recently. These take around 2W on their own.
Yes, but if you use solar powered ones then you can use the output of the lights they control to power the sensor and the power will be for free!
