We have had one of these lights in use since December 2008 and it is still going strong. We use it to light a dark alley between the house, the garage and a tall wooden gate. The light given is plenty to ensure that we don't step on a hedgehog or put our hands on a big furry spider when trying to unbolt the gate!
The solar panel simply sits on the flat garage roof. A matter of minutes to screw the bracket for the lamp and P.I.R. unit to the wall.
We have now obtained a second unit which is in use lighting the patio, not good for reading at night, but excellent for picking a safe route between the patio pots. One surprising thing, in 2008 it cost £24.46, now it's only £16.79.
Easy to setup, effective light when you don't want to blind your neighbours with a 500W Halogen lamp or would have a challenge to cable up a mains powered lamp.
