After the very fast delivery I was curious about the optics and optical power of floodlight. The construction was done absolutely unproblematic and fast. The Deckenluter looks with the oval glass element of good that is Verarbeiung total i. O. Very good I find the light output. The ceiling lamp is exceptionally bright at full power and is enough for a 20 - 25 sqm room completely out. A hardware store in seen, visually similar model, on the other hand is totally disappointing. The reading lamp is in a good light output. Both can be dimmed. The color temperature is a little higher, not necessarily warm white, but is still comfortable for the living area. Would I buy again at any time.
