There is a bracket that screws into the wall- the light is screwed into the bracket. It can be attached to a brick wall using a masonry drill bit, and the screws provided.
It is a decorative light and therefore we are not able to provide a lumen rating for it.
Hi Gerard, on the very overcast days we do recomend to switch the light of for a few days for the battery to gather a booster charge.
Hi Andrew, the width of the bracket where the screw are is 4.5cm from screw to screw its about 3.5cm. If you want the bracket to sit nicely on the leg 4.5cm minimum
Hi Anna, there is a manual button to switch the light on and off. The black lid that the pannel is sitting on can be opened turned clockwise as you would open a lid on a bottle.
