Looking to control your desk lighting? In this video, we review and teardown a USB LED dimmer switch to see if it's the right upgrade for your setup. We test the PWM dimming performance and check for flicker, so you know exactly what you're getting.
You will see how the dimmer works with USB-powered LED lights, how smooth the brightness adjustment is, and whether it introduces visible flicker at low brightness levels. The device is opened for a PCB inspection, component identification, and measurement of the internal circuit board. We also identify the DP3080 controller used for LED dimming.
⏱ Chapters
00:00 – USB dimmer test with LED light
00:20 – Brightness control demonstration
01:05 – Opening the case and teardown
01:22 – DP3080 controller inspection
01:51 – PWM flicker test at low brightness
Technical observations:
• USB powered dimmer switch
• 5V input, rated up to 2A
• 8 brightness levels
• Compact PCB design
• Suitable for LED strips, USB lamps, and custom lighting projects
