Why did some of my lights go out?

More often, the issue is a blown fuse or tripped circuit caused by excessive electrical current flowing through the wires. The fuse or breaker will automatically cut off the current to prevent the wires from overheating and causing a fire.

Why are my lights not working but power is?

If your lights are working but your power points are not working, this is generally due to the safety switch being tripped by a faulty appliance. What is the safety switch? Safety switches provide personal protection against electric shock by monitoring the flow of the electricity through a circuit.

How long do ceiling lights Last?

While incandescent bulbs typically last only around 1,000 hours – barely a year with several hours of use each day – LED lighting is commonly rated to last 50,000 hours or more, which can conceivably translate into decades at the same rate of use.

How do you make a light bulb work again?

A switch circuit that doesn’t operate correctly may simply have a tripped breaker or blown fuse. Head to the electrical service panel and locate the breaker or fuse. If the breaker is tripped, reset it; or if the fuse is blown, replace it with an exact duplicate.

How do you find which light bulb is burned out?

You can tell which bulb is out on your string of traditional Christmas lights by looking for the bulb that is “burned out” by looking at the tiny little filaments in the light bulbs to see which bulb is “burned out” or has lost it’s filament. Many times the bulb will be “smoked” as well.

How do you find the bad bulb in a string of lights?

Simply bring the light tester close to each bulb. The tester’s indicator will light up when it’s near a functioning bulb. If you have a non-contact voltage detector, bring the detector close to the wire section between each bulb to test for voltage. The dead section of wire will be the section after your bad bulb.

Why did my LED lights suddenly stop working?

This problem has two possible causes. Either (A) You you have a 24V power supply connected to 12V LED strips. Or (B) there is a ‘short’ along the strip – in other words the solder has gone across the PCB somewhere and the +ve and -ve are touching, shorting the circuit.

Do LED ceiling lights burn out?

LED lights cannot burn out because there is no use of heat as in incandescent bulbs, or gases to burn out or wires to burn up. The microchip inside the LED produces a small amount of heat, which is taken away by the heat sink, meaning that no parts in the bulb are designed to burn up.

Can LED lights be repaired?

A great benefit to LED bulbs is you can repair almost everything. Premature burnouts can be caused by poor component quality, LED overheating, and voltage jumps. The good news is that you don’t have to have a lot of experience to handle the repair and the cost is significantly less than the price of a new bulb.
