Inside a Timeguard coolglow nightlight with unusual glow tube.

I remember seeing these in the past. They're a night light that uses a little fluorescent tube as the lightsource. The current limiting is very simple, but the method of initially starting the tube is quite unusual, and very reminiscent of a traditional mercury lamp.
This product appears to be discontinued now, but might still be available online. It's intended for 220-240V use.

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
