Testing a compact 24 LED USB light stick for emergency lighting or clean desk setups. Honest review, real brightness test, and practical inspection.
What it is: A durable, minimal 24-LED light stick powered via USB, equipped with a rear touch sensor.
How it works: It uses standard resistors to regulate voltage. Drawing only 0.43 amps at 5 volts, it stays under 36°C, ensuring safe and reliable long-term use without overheating the chips.
Application: Provides even and bright light distribution to read, illuminate a workspace, or build a functional blackout kit.

⏱ Timestamps:
0:00 - 24-LED USB lamp and touch sensor
0:05 - Power consumption and wattage test
0:20 - Operating temperature check
0:29 - Exact dimensions for a minimal kit
0:34 - Printed circuit board overview
1:06 - Brightness test in a dark room
1:26 - Comparison with previous lamp and power bank
