Visolight D282 (1850lm) Light color 4000K

First of all I want to say that I have the Visolight D282. This, however, is basically identical to the D280 (the housing is identical).
The only difference is:
D280: 24 LEDs (21W) equ. to 120Watt
D282: 32 LEDs (21W) equ. to 150Watt

In addition, the D282 is still dimmed, but beware! Not a Phase or phase dimmer, but by an external power supply (2-12V). What are the options here from Merten, Gira, Busch-Jäger, etc. on offer, I do not know (I would be interested even).

In any case, the D280 and D282 which have an integrated potentiometer, via which the light intensity infinitely variable from about 50% - 100% can be regulated. This is absolutely great, because as you can adjust the light intensity of each area. Formerly one was also always stupid because: I now take a 40W, 60W or 80W lamp for the room? The superfluous by the potentiometer.

I use the D282 with a light color of 4000K in the kitchen. After the first start I was quite amazed, the kitchen was bright as day and into the last corner (no shadows or dark corners). The kitchen is 11sqm in size (approx 2,4x4,5). I have also reduced the lamp above the potentiometer by 50% and it is really absolutely daylight.
The manufacturer writes that the power is proportional to the potentiometer changes position. The end stop of Poti, 50%, or about 11 watts. Maximum there are 21W. I have my pot stand in the middle, so 16W and that's enough thickness!

Before hanging there a 100W light bulb (conventional) and this was a real Funzel opposite the now 16W LED lamp consuming. I will also equip other rooms such as hallways, bathrooms, bedrooms, etc. with this lamp. The bathroom probably with 4000K, 3000K with the other rooms.
