I ordered the warm white version (Visolight D280 LED Wall and Ceiling lamp 1700lm warm white), due to other reviews, in which the light was still described as a relatively white. This I can confirm. The light color is but still not cold. To my taste perfect for a kitchen. Maybe I'll buy yet which for the staircase. I run this light in the power set at the factory, have tested no lower setting, so can not judge how the light color effect in reducing the power.
Previously, a ceiling light with two bulbs was the light source for the room, they had a similar design as the Visio Light lamp but even two 60 watt bulbs would not have the brightness of the LED light reaches.
The light diffuser is curved, this favors sure the light distribution in space and can be simply removed and attach.
The design fits best determined in kitchens, corridors, basements and workrooms. In living rooms one would particularly check whether the appearance and color of light fits into the overall picture.
To assemble:
Regarding the assembly is very easy, which is of course, when working with electricity, know what you're doing.
The mounting hardware, the two screws and anchors can operate safely in most cases. In my case, I used a little shorter wood screws for the wooden ceiling.
The Wago terminals for the electrical connections are very good. While pressing a finger or screwdriver to the respective terminal, you can simply insert or remove the line, the head if you let go of fixed.
The conclusion:
The lamp makes a high quality impression. The design is neutral. The light output is super with low consumption. When good quality / price I would buy them back for sure.
