Thanks, I'd thought about a battery 12v solar system, but in winter it's a lower sun and I have very high trees to three sides of the garage. I need battery and I think, rechargable too so I can leave them without worry.
Battery operated PIR type light ? I have a couple of 'expensive' LED's at my caravan that are very bright, but a cheap £9.99 LED PIR light at the back of my garage - it's OK for finding your way, but you won't be working under the light - runs on AA's. The 'expensive' ones are far brighter (£30-£40 each), but run on C cells, and are much more useable.
