I bought a bunch of these (https://www.amazon.co.uk/Outdoor-Garden-Lights-Ground-SPBLK04/dp/B008WAE128/ref=sr_1_5?keywords=Gu10+garden+spike&qid=1581015350&sr=8-5 ) and stuck them around the garden, all wired back to switches at the front/back door. What I like about these is that they don’t come with bulbs, so you can change the bulb if they fail or put different coloured or smart bulbs etc in.
Note that you can buy these spike light fittings in electrical wholesalers here for x3-x4 times the price, which I assumed meant they were better quality and the Amazon stuff was cheap junk. Not so, they seem to be all more or less the same...
