content: I saw this too and LED bulbs are now on position one in my list of "Chinese products that will kill you" right after USB chargers.A more detailed video on this subject (especially with proper measurements) would be interesting.......Dave....hint, hint

content: Did the manufacturer say it was safe to touch while turned on?Although they could've made it safer by putting a transparent tube around it...

content: "transparent tube" = money ;-)Even if the manufacturer writes, that you shouldn't touch it, it's not ok.Imagine that a child grabs the bulb and gets shocked.An incandescent light bulb isn't save to touch, too but the worst thing you can get from this is a burn.

content: What does that even mean, electronics man? What is it a fake of? It seems to work, but it's badly designed and quite hazardous. It's obviously a rip-off of some other product, but that doesn't equal "fake". "Fake" implies that it doesn't even work.

content: QuoteI wonder if I'm missing something there: the chap is annoyed with the safety implications of those lamps, so he zaps it in his lab which includes a transformer on the floor with exposed mains and HV connectors, and a wooden ceiling and walls plus carpeted floor where things are going to fly around in a hot, possibly burning, state. Nice collection of paper on the roof too to catch and spread any flaming bits.Wonder if he has any videos he's too embarrassed to show
