Pros: interconnectable up to 8, super-slim, bright, includes magnetic mounting
Cons: pricy compared to fluorescent
Considering there's a lot of manufacturers making under-cabinet lights, and seen them in action, I found this strip and it's definitely one of the brighest. Some strips are cheap but they use the first generation low power LEDs. This one uses high power LEDs, and claims 80 lumens/watt - whereas most other products from other companies range from 40-60 lumens/watt.
I liked the fact that the back of it comes with a magnet embedded into it at either end, and comes with double sided tape mounting as well as screw options. With the screw option, it also swivels so I'm thinking of buying these for a display cabinet as well.....another $100.....soon enough...:o).
