💡 Efficient Portable Handheld Neon Tube Lamp Fluorescent LED Tester: A Must-Have Diagnostic Tool Review

It does exactly what it is supposed to do. I was disappointed at first until I turned off the lights and tested the neon lights and he showed which lights worked and which didn't.

works well make sure the batteries are installed correctly hold the button down while the led is flashing and touch the bulb with a wand and you will see how it glows when it's good instead of glowing when the bulb is bad. The delivery was fast, the seller answered all my questions. great little tool.

Tests light bulbs to see if they glow or can glow. No pin test, but you can still do it with any ohmmeter, so it's way better than the $100 competitor. It would be nice if they sent a Chinese instruction manual!
