Lighthouse IP65 Ultra Efficient LED Black Aluminium PIR Floodlight   £12.95

This is a high quality product, having bought cheaper store equivalent lights before that rusted and leaked within 2 years I immediately noticed the superior build quality of this light. It heavy and needs a secure fitting please note but nothing that can't be done by anyone with a drill and screwdriver.
One disappointment was the absence of a user manual but the instructions are on line.

I bought two - a 10W and a 30W and found them easy to mount and connect. No issues and they are lighting up my sideway and terrace respectively. Just what I needed.
