bigclivedotcom | AliExpress "explosion proof" Chinese factory test box @bigclivedotcom | Uploaded August 2024 | Updated October 2024, 8 hours ago.
Although seemingly used in many Chinese factories, this unit is not compliant with electrical standards in "safer" countries.
It's described as an explosion proof tester - but that doesn't mean it can be used in high risk explosive environments. It just means it has a series load option that prevents faulty devices exploding, by limiting the current through them.
As with all these Chinese factory test boxes, they take a rather slack attitude to electrical safety, and the lack of polarity, exposed bulb threads and misuse of speaker connectors for 220V (China's supply voltage) means that the unit poses a shock risk to the unwary.
Still better than the two nails in a bench I've seen being used to test bulbs in some factory videos.
I suppose that one of the screw-in ceramic vivarium heaters could be used as a safety load too if the tungsten bulb it's designed for is hard to get.
These units are sold on AliExpress as LED bulb testers. But I really can't recommend them for safety reasons.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- bigclive.com/coffee.htm
This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty.
