Free Lighting

Well, apart from buying the lights it's free.
Flat solar panel, about 6 inches square screwed to the hut roof, wires fed through between the roof and the wall to connect to the LED lights (10 in each light) and Bobs' your Uncle. We now have lighting in the shed.
There's an amazing amount of light comes in from the two square skylights in the roof but they don't work so well at night, when it's dark, hence installing the solar lighting!
