NOTE: CE does NOT mean China Export, it's just a mis-spaced CE logo (just like the one on the back of an Xbox 360). https://en.wikipedia.org/wiki/CE_mark... Comments mentioning China Export will be marked as spam automatically, because it's horseshit.

Based on feedback comments on my earlier video and a request from the folks at http://www.avforums.com/, this is a shorter test on a range of "corn cob" LED lamps available on eBay and Amazon.
If you're thinking of buying cheap LED lamps, whether it be online or from the local market, this video is for you! Of the six "corn cob" style LED lamps tested here, only ONE could be considered safe to use. Watch the video, know what to look for in a safe bulb and know the risks associated with the dangerous ones!
Some details left out of the video: At 50mA-100mA, ventricular fibrillation (very rapid uncoordinated contraction of the ventricles of the heart) is possible. Hand-to-hand body resistance of an adult lies between 1,000 and 4,000 ohms, depending on moisture, muscular structure and voltage. The average value is 2,100 ohms at 240V AC. (source: Basic Industrial Electricity: A Training and Maintenance Manual, Kenneth G. Oliver, p156) If your resistance at the lower end of the scale the current will be higher and the 100-200mA range is where you're at highest risk of fibrillation (and CPR won't fix fibrillation, you need a defibrillator for that).
Apologies if some of it sounds a bit scripted, that's because it IS scripted to stop me rambling quite as much as usual, I'm trying to strike a balance between brevity and detail here, and it's tricky!
