usb led light testing @LittleBabyBum

To test a USB LED light, you need the following materials and steps:

### Materials Needed:
1. **USB LED Light**: The device you want to test.
2. **USB Power Source**: This can be a USB wall adapter, a power bank, or a computer USB port.
3. **Multimeter (Optional)**: To measure voltage and current if you want to check electrical parameters.

### Testing Steps:

1. **Visual Inspection**:
– Start by examining the LED light for any visible damage, such as frayed wires, burnt spots, or broken components.

2. **Connect to Power**:
– Plug the USB connector of the LED light into your chosen power source. Ensure the connection is firm.

3. **Turn It On**:
– If the LED light has a switch, turn it on. In most cases, it should light up immediately upon connection.

4. **Observe Operation**:
– Check the brightness of the light. It should be steady and free of flickering. If it flickers or is dim, there may be an issue with the bulb or the power supply.

5. **Measure Voltage and Current (Optional)**:
– If you have a multimeter, set it to the appropriate mode to measure voltage. Connect it in series to check the current draw. This can tell you if the LED light is operating within its specifications.

6. **Heat Check**:
– After the LED light has been on for a while, carefully feel for any excessive heat, which could indicate a problem.

7. **Turn Off and Disconnect**:
– After completing the tests, turn off the LED light and safely disconnect it from the USB power source.

### Conclusion:
By following these steps, you can effectively test a USB LED light for functionality and safety. If it fails any part of the test, consider replacing it.
