Done exactly this sort of setup on my narrowboat and garden office, so fairly familiar with the 12V lighting rabbit hole.
Honestly, the easiest starting point is a simple fused distribution block fed from a leisure battery. Something like a 100Ah LiFePO4 — Fogstar do decent budget options — will power LED strips or spot lights for days without breaking a sweat. LEDs draw almost nothing.
A few things worth thinking about early:
- Cable runs — plan where your lights go before you start hiding cable under cladding. Bitter experience talking here.
- Switched circuits — even a basic 2-gang switch panel keeps things tidy rather than hunting for individual switches in the dark
- Warm white vs cool white — cabin vibes absolutely call for warm white, trust me on this
If you want to keep it dead simple, those 12V LED strip lights with inline fuses are plug-and-play enough for a shepherd's hut. Just make sure every circuit is properly fused close to the battery — don't cut corners there.
Longer term, a small solar setup on the roof with a Victron SmartSolar controller makes it self-sufficient. Even 100W of panel tops a leisure battery up comfortably through summer.
What's the size of the hut roughly? And are you thinking battery-only or will you have any mains hookup available? Makes a difference to how you'd size everything.
