Garden Lighting (and mice)

The grumpy garden has, for some time, had a number of LED solar lights - bought from Macro - glimmering away, and also slowly falling apart. While in B&Q the other day, I noticed a selection of 12v garden lights reduced. I'd never intended to have wired lights in the garden, but Mrs Grumpy was getting, well, grumpy, about the state of the solar lights, so I took the plunge. These are Select-A-Lights from Ring, who are based in Leeds.
This is a 12 volt DC system, and I bought the 60w transformer, the PIR/Timer unit, 25metres of cable, 6 LED post lights, and 4 path lights. Not cheap in the end, but the effect is good.
The photosensor is set too dark - so I need a way of getting the thing to come on earlier in the evening, of course there's no adjustment - don't be daft! The PIR is very sensitive - which in my mind is a good thing. I'll probably leave the unit to come on at dusk, leave the setting to 3 hours (there's also a 6 hour setting, and a dusk-to-dawn) until it's too cold to use the garden much then set it to use the PIR.
The lamps appear to be well made, but the connectors are an abomination! I resorted to using the block connectors, wrapped in self-amalgamating tape, then closed up in the daft little boxes supplied. The transformer, intended to be left on all the time gently warms up, so it's using power all the time - not too green that! I'll put a timer on it, so it's only on between, say 5pm and midnight.

I was actually in B&Q looking for mouse traps - for the garage. Sorry, but forget humane, these little beggars need to DIE. The plastic 'modern' traps are not very impressive, but the traditional wood and wire traps seem to be working - two deaths so far , using peanut butter as bait. Yeeeaaah!
