A P59 (1 USD) USB light bulb that can be useful for power outages, camping or to use as cheap video lights.
In this video, the comparisons I made were actually of a much older LED bulb being sold by CDRKING. After shooting this, I realized the previous generation was very similar to this, although it used a different LED, different resistors and a different (faulty) cable.
The previous generation was actually a bit brighter but pretty much every single one had problems with the cable so I'd still consider this an upgrade.
I'd certainly recommend you buy a USB powerbank and USB lightbulb instead of one of more expensive 'emergency lights' being sold at hardware shops which use lead acid batteries.
