It's been quite a slog, but I now have the system up and running.
I had already sent several emails to the LongLifeLamp company and received no replies, telephoned in and gotten separate emails from their ones stated on their website, with promises to return existing emails and even telephone callbacks, but nothing.
I can categorically say that the LongLifeLamp company is rubbish in both pre and post sales, just utterly useless, don't bother with them. However, they are only a reseller, the company who manufacture the lights are in China (surprise, surprise!) and the product is good, for the price.
I decided to get both the PIR and the LED lights, with a Multimeter (
https://www.amazon.co.uk/gp/product/B00TM0W8ZY/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1) to test for myself. I have an electrician friend and paid him in home made beef jerky for his time, where he showed me how to do something called a "Continuity Test" that would confirm if the polarity at one of the PIR was the same at the other end, meaning that it didn't matter about the polarity for the PIR because it would simply keep it the same the other end - it passed the test and so there's no issue.
The barrel sizes fit perfectly, but because I don't have any digital callipers I cannot be sure, but by eye I can be 99% sure they're the same barrel size!
The lights came and guess what... the one thing I purchased them for (the plug) was not as described on their website - I was severely disappointed because I could have gone with anybody else, anybody, but needed this plug. The plug was white, with the exiting cable from the top, not the bottom (as it shows now). These style plugs can be had easily enough in black, but not white! So I rung them up to find out what was going on and did manage to get through (after a couple of attempts) to somebody who knew a bit about what they were talking about to tell me that because of UK safety rule changes a couple of years back the plugs that they used to sell (the ones pictured on both their own website and on the Amazon webpage) were now illegal and had to be junked! They still had them but couldn't sell one to me, unless I made a trip to the factory in China! The plugs worked, no issues, but they were not sufficiently waterproof and the standard had become more demanding so they moved the exiting cable to the bottom of the plug.
I was really annoyed and disappointed that this knuckle-dragging company hadn't updated their imagery in the preceding years (they have since my purchase last month, after pointing this out) and couldn't help me!
I needed a top exiting plug to keep the kitchen surface clutter free, it also had to be white, like the rest of my kitchen.. where was I to find a plug like that.. nowhere, not online, nor in the high-street!
However, I got lucky and found an old Foscam (IP CCTV) off-white plug that fit the bill, if a little blocky (

I wish I could have gotten the original and sleeker one though, I just can't fathom why the industry says away from white?!
Anyway, the whole system is up and running! Yea, it was a bit of a hassle to set the PIR, but now it works and it feels like the Star Ship Enterprise, I am still getting used to it, it's as good as I thought it would be.
