The light Visio Light D280 makes a high-quality impression, the processing appears extremely neat. The casing is painted white, it looks in the picture or product description of somewhat ambiguous. The lamp looks simple but yet elegant. The diffuser (plastic cover) can be attached to the housing by gently twisting and it has a good grip. A built-in potentiometer allows the power consumption of 11 to 21 watts measured continuously adjusted. My evaluation of brightness and color temperature refers to the 3000-K variant. Set to minimum brightness, equivalent to the luminosity felt a 10-12 watt LED bulbs, the light acts but warmer than the used for comparison LED bulbs, even though these are indicated with a color temperature of 2700K. So as a result, one in terms of controllability absolutely inovative luminaire with a pleasant light and the ability to vary in brightness between a conventional 1- and 2-burner lamp. And those who prefer to have whiter light, can choose a color temperature 5000K or even 4000. I currently have no other light on the market found that also has so many possibilities of customization.
