Do you need to change the transformer for LED lights?

They will have a transformer either in the ceiling or light fitting.

In other cases, you need to replace the transformer with an LED driver.

Can you put a LED bulb in a regular fixture?

LEDs can be used in any light fixture, as long as it’s not enclosed or air-tight, and is not an old-style dimmer system. Both these will shorten the lifespan of LED bulbs.

Can flickering lights be caused by a bad breaker?

See CIRCUIT BREAKER FAILURE RATES – a bad circuit breaker or electrical panel connection can cause flickering lights or loss of power. … Since a failing circuit breaker or device sometimes (not always) suffers internal arcing that produces a buzzing sound, that clue may also be diagnostic. Switch such circuits off.
