The ceiling light that also cools

Like a round ceiling light. The four blades retract into the body of the appliance at rest: from the outside, nothing tells the Boréal 107 apart from a conventional ceiling luminaire. They deploy by centrifugal force when it starts.

The Boréal 107 uses a dimmable LED with three colour temperatures, from 2700K to 6000K, and a colour rendering index of 97 out of 100. Most ceiling lights on the market do not state their CRI, and those that do sit around 80.

No. It connects to the existing light point, to the same three conductors as a ceiling light: live, neutral and earth. Allow half an hour. The only thing to check is the mounting, which must hold a rotating appliance, so a purlin, a rafter or a concrete slab, never plasterboard alone.

More than a flat luminaire, less than a downrod fan. The rule is to keep 2.10 m between floor and blades; under a ceiling of 2.50 m or more, every model fits. Below 2.50 m you need a profile specifically designed to mount flush.

Then a ceiling light will do, and it will sometimes cost less. The point of this one appears if you also want to get through summer without air conditioning and winter without heating the ceiling: two functions on a single fixing point, for the price of a mid-range luminaire.
