Alvin three-blade ceiling fan with light and two modes for summer and winter use Alvin has three dual-coloured blades - one side is beech-coloured, the other silver. The blades can therefore be used on both sides. Functionality The lighting is an additional benefit as it means that no second power connection on the ceiling is needed, which is of course very convenient. Alvin has two modes so that it can be used both in summer and in winter. The mode can be set via a switch on the body of the fan. The remote control can be used to switch the fan on and off as well as to set one of the three different speed levels.
