The normal is 3 meters away, the transformer capacity is small should not be a big problem, more than 250KVA, the sound will be loud at night.
There is no harm in the distance of more than 4 meters, but rest assured.
Generally, manufacturers should take into account the power of the bulb and the heat generated by long-term use, and the effective heat dissipation space between the bulb and the lampshade when designing the lamp, so that there will be no safety accidents such as sudden explosion of the lampshade when heated. Therefore, there are two possibilities in your situation: 1. You have changed the power of the bulb to a large one, so that the increased heat cannot be dissipated in time, resulting in the overheating and fragmentation of the lampshade; 2. It's just a low-probability accidental situation--- the lampshade itself has quality defects, just you "won" it, and it should be okay to change the cover of the same type and specification.
It may be an LED, etc., it is an energy-saving lamp, and it will be on again after it is turned off.
You use a sectional switch, which has 2-stage, 3-stage, 4-stage, with and without remote control. According to your description, the segment switch should be broken, and you can replace it with a switch with the same number of segments. The segment switch is inside the lamp.
