I like the idea of having the PIR separate so you can just have a switched live going to for manual switching.
Relay output PIR ok for the photocell one? The mfr website is a bit shit for wiring diags & so on.
Is there any point having the photocell version with a seperate PIR as most PIRs already have a built in photocell?
Good point . . . .
Now to find a PIR that doesn't have 'helpful' override modes, if stuck I might end up using a burglar alarm PIR and use a photocell floodlight after all.
Burgular alarm PIRs tend to have a 1 second timer!
I have fitted the non photocell versions with seperate PIRs and all was well:-)
Personally, I use a 35W CDM-T dusk till dawn flood light at my house. A very bright and very white light. At least the same light output as a 300W halogen.

Just been down to test them - still dusk and ample light to see/read with. They create shadows and give a nice warm light without the hard edges you get with a halogen flood. I would say they are about the same as an 80W tungsten, probably more. At 10W a piece, even if they do get left on, it is not going to be the end of the world.
I will be getting some more to replace the halogen floods next time the bulbs go.
(They were 25 UKP each on ebay - need a three wire PIR - i.e. not one of the ones you wire in series with the lamp, it needs its own feed)
Having looked on ebay there are single or multiple LED floodlights rated at 10W? Not sure I trust a single 10W LED just yet but what happens to multi LED one after a few have failed...
First saw the single LED ones at the Eden project in the domes where all the paths have them as low level lighting.
different tubes, different ballasts.

Have now fitted a few more and becoming convinced that they are better than 100W each. I have 5 down the side of the church (about 30m) and they provide a nice, even, warm white light which is better than a dull day. Very impressed, getting some more for the other side.
