A LED light bulb is a modern and efficient light source. … Traditional incandescent light bulbs cannot be repaired at all, while in LED bulbs you can repair almost everything. You just need to find the malfunction, make some repair and prolong your light bulb lifetime.
What happens if my LED light stop working?
If the LEDs will not light up at all, then this could be down to a faulty power supply. Solution: If you have several power supplies, then try a different power supply onto the same strip to see if this now works. If it does, then you have a faulty power supply and will need a new one.
Is LED tube light repairable?
Since the LED Tube-Lights are very costly, And by this video It is proved that it can be repair easily at home.
How do you test if a LED light is bad?
Connect the negative lead from the multimeter to the cathode (negative) lead on the LED. The LED should glow dimly, indicating it’s working. If the LED does not light, swap the connection to the LED leads. The LED should now light, if not the LED is faulty.
What causes half a string of LED lights to go out?
If one of your LED light strands isn’t working, it’s probably just because it has a bad bulb. If one bulb dies, it can cause the rest of the strand to stop working. The only way to fix the problem is to find the bad bulb. Sometimes only a section of the lights will go out, making your job pretty easy.
Why are my LED lights 2 different colors?
If two primary color within the group of three LED elements are missing, this simply means that two surface-mounted components (resistors) have been damaged. Observe the PCB strip around the location of the missing primary color (red, green, or blue) and see if you see any damage.
Why wont my LED lights turn red?
Most likely it is a poor connection on the Red wire, A standard DVM meter will test LEDS like these, just set to Ohms and place the leads across a red LED and see if it lights up. If that doesn’t do it, reverse lead polarity.
Can LED lights burn out?
Unless an actual component in the LED fails, they will provide light “forever.” While LEDs do not burn out like fluorescent lamps and other bulbs they will, however, degrade and dim over time. The diode itself will begin to emit less and less light as the years pass. Still, LED lamps can last over 25,000 hours.
What is the price of LED tube light?

Why do LED tube lights flicker?
LED bulbs don’t have glowing filaments. When the dimmer switch goes off and on many times per second, the LED bulb becomes a flickering strobe light. In rare cases, the flickering can be some other power supply issue, which may be the explanation if you don’t have dimmer switches.
How do I test my LED driver?
LED drivers are usually tested in one of the following ways;
- Using LEDs.
- Using resistors for loading.
- Using Electronic Loads in Constant Resistance (CR) mode, or Constant Voltage (CV) mode.
What causes led drivers to fail?
When an LED stops operating before the end of its rated lifetime, it can usually be saved if the driver is replaced. Drivers often fail prematurely due to high internal operating temperatures. Battery-like components called electrolytic capacitors are typically the cause of death.
Will low voltage damage LED lights?
Underdriving will not damage the LED, in fact will increase its lifetime. One cannot underdrive an LED with too low of a voltage, since the LED will simply give off no light if the voltage is too low. (The difference in voltage needed for lowering the light output is very small.
