The living room cat s eye lamp is 15 meters around the wire, and the wire is connected to three head

According to the description, maybe the driver of the light fixture in your home is broken, so you can try another one.

30 square meters of living room, do not use the main light, only install downlights, generally how far a downlight lighting capacity can cover how much area depends on how much power you choose, the general family does not need to be too dense, at least one meter five or so to install a 13W....

If the switch is made together, put two wires in the area where the light is to be placed and go around.

In fact, choose a distinctive main lamp, that is, there is a lighting effect, more decorative effect, otherwise the living room will look empty!

It should be a transformer (fire cow) problem.
