Powerful LED Replaced
Received a 100 watt LED Outdoor Light for repair with the complaint of dim. Inside the casing there are two powerful LEDs. In order to check the LED, one has to turn the light on and measure the DC supply voltage. If the DC supply is lower than the normal voltage then the LED will be dimmed. If the DC supply check to be good then suspect a bad LED light.
In the below photos, I have tested the DC supply which was 109 Volt and it was a good DC supply voltage to both the LEDs. This means both the LEDs light have problem because it suppose to be super bright once it received the 109 vdc volt.
Since these LEDs light can’t be repaired, the only solution is to replace with two new LEDs light. I bought it from the local market.
Before you fix the LED light make sure you apply lots of heat compound and this can helps to dissipate heat faster.
If you did not apply the heat compound or did not put enough heat compound, the LED light span will be shorter due to overheat-see the two photos below:
Once everything is fixed and powered On, the light produced by the LEDs were super bright.
Conclusion: It is a very straight forward repair because the DC power supply was working and getting the original LED light from the market was not a problem at all. Assuming if the DC supply has no or low output then I will focus on repairing the power supply and it will be different story from this article. All the best to you.
