I use these in various sizes in my garage. Brighter than the multitude of fluorescent tubes I replaced and so easy to fit. There is a cable coming out of one end you connect and then the light just clips into some spring clip holders.
The lights are light (unheavy) enough to be held with a single clip if necessary.I have one above the side worksurface near the window mounted closer to the wall rather than directly over my head to avoid shadows. During the day, the window gives enough light but as the evening comes, the light is perfect and the daylight tone is much nicer to work under than the bright white I have in a couple of other places.
They are also cheap enough that I ended up fitting more, smaller units as it was easier for me and gave a greater spread of light with no shadow areas.
