1st question answer: You need to increase the voltage received by the bulb
2nd question answer: It is just the contrast/opposite of question 1; All you need is to decrease the voltage that the bulb receives
Explanation of 1 & 2:
The brightness of a bulb, like the sun in the solar system, are based on the energy it has. Both has similar properties; light emission: To emit light, it needs energy which is represented in voltage (V) to heat the tungsten filament inside in which is brighter when it receives more energy to become hotter. This means that a bulb brightness (or dimness) coexist with voltage or the amount of energy it has.
3rd question answer:The main cause of an exploded or busted bulb is overheating.
Explanation of 3:
it can be because of a loose connection of the bulb to the bulb socket or a sudden surge or change of the voltage it receives usually during a storm where the transformer of an electric pole is struck by light lightning.
