Not exactly woodwork related ( apart from the frame to go around it 8) ), and me being reluctant to spend £20 + for a light for the shed, i made my own led light panel out of some scraps of polycarbonate sheet and some led strip i got from china, total cost including some silicone less than a fiver, i stuck the leds to one side of the polycarbonate sheet then siliconed another sheet of poly on top to sandwhich the leds in place and create a diffuser, let it go off for a few hours, then i soldered some cable terminated with a cigar lighter plug, to use in my portable power pack or direct from the car socket, i don't know the exact power output or usage but it works well, when it gets dark later will post some more photos of it's brightness, cheers,
