Lighting difficult

We have no neighbours and no street lighting, so it’s dark here and we could really do with some outside lighting. Mains lights are tricky because our walls are 3 feet thick and exceptionally hard to drill through. We’ve tried push-in solar lamps, which were a waste of money as they all stopped working within a year. Are there better quality solar lamps around? I don’t trust online reviews because most people seem to review within days, and never update to say it’s still working - or not. We mainly want to light the steps up to the house a bit.

the plastic has yellowed a bit, but they have been out in the garden for some time!

The Powerbee ones recommended by @TheVanguard are cheaper direct from Powerbee for 1-4 lights, at the moment. Amazon are cheaper for packs of 6.

Low voltage led lights have a very thin wire is there anywhere you could get that into the house say through a door or window frame or air brick then you can plug the transformer into a power socket along with a timer.
