Have been looking for a flat, bright built-in LED, this one has an extremely low installation depth of 13mm. Another advantage is the direct direct 230 V connection. I've built 16 of these lamps in the ceiling, at comparable solution with a transformer (eg. Paulmann always 3 lamps in series) I would still have to accommodate 5-6 transformers. Brightness: just great, would say comparable to a 40W halogen spotlight. Light color: very close to daylight, not yellowish like a light bulb, like very well with personally. Optics: aluminum bezel looks very valuable, no comparison with alternatives I had to choose.
