Here's what I use in the 3m x 3m shed. It's a AA battery (3) operated detector light and it illuminates the shed well enough as soon as you walk in. I got mine through global shop direct but have seen the same under another brand at SCA. Only irritating aspect is shutting down when you're doing something. You can either switch from auto to on or wave your arm toward it to trigger it again.
I use rechargeable NiMH cells.
