Very good bulb

The emitted light is really good in the sense that it covers a wide spectrum of colors (the big concern of many competing models being at this level with potentially light "white / yellow" on a white wall or skin but appears greenish for example).
It also provides good uniformity, no holes, no more enlightened than other areas.

Stupidly ceiling mounted on an angle construction pellet is large enough that the ceiling is illuminated from 7 to 8cm around the base. With less force than in the center, certainly.
The light output is actually equivalent to a 60w 75w see a classic and replaces 42w halogen successfully.

My only criticism is actually directed to all the actors of the LED bulb market, why propose a very warm warm white 2700k to overall warmer than a halogen bulb, or the opposite of 6000k and more for the blue light and nothing in between? Why not 3500 / 4000k?
