I'm wondering if anyone on here has tried them and if so what they think of them. They appear to be everything I need, and the only thing they seem to lack is a means of setting the run-on timer. They come preset to 40 seconds, which should be fine for most situations where you only need light when you have movement. (You couldn't use one in a toilet where you would be having to wave your arms just to keep the light on!) Here is an example of the sort of thing I'm referring to (https://www.ebay.co.uk/itm/184722046075?hash=item2b024abc7b:g:me4AAOSwLZRgWGeV).
