Glowing LED problem: technical explanation with 5 possible fixes

This promised video is long overdue. The nuisance glowing or flashing of the LED is due to the way the wiring capacitances add or subtract with a susceptibleLED bulb. I hope I have explained more clearly in this video. The original video was to demonstrate the problem where the LED bulbs keep glowing when they are physically switched (or turned) off, at a standard light switch. Please note that if you have a dimmer switch it's really a different problem due to let by current but I will try and make a video addressing that issue in the future. Other than the first suggestion of getting the correct LED bulb, the other solutions are unsuitable for non electrically qualified/competent people to implement. So for the other solutions you must consult a suitably qualified electrician to fix this for you. video contents chapter thingy 0:00 introduction 2:00 explaining the kit I'm using for the demo 3:12 Showing the bulbs in normal operation as baseline 4:25 general recap of why the issue happens 6:36 visual emulation of described issue, on equipment 8:01 1 of 5 ways to fix:(get the right product) 8:22 explanation of correct wiring normally recommended 8:50 visual emulation of using correct wiring 9:10 explanation why it didn't work in this instance 9:58 simplified schematic diagrams of both circuits using capacitors 12:35 2 of 5 ways to fix:(ensure wired correctly) 12:45 woolly explanation of why we have an earth in lighting these days 13:35 emulation of a bad wiring setup (switched neutral) 14:50 how you can identify the correct product (difficult) 15:37 emulation showing how earth makes a difference when wired properly 16:34 3 of 5 ways to fix: (using a shunt bulb) 17:19 4 of 5 ways to fix: (using a shunt resistor) 18:20 why you need to be very careful when choosing a shunt resistor 19:29 demo using an 820k shunt resistor 20:15 considerations for location and placement of shunts 21:05 5 of 5 ways to fix: (using a shunt capacitor) 21:47 demo using a 2nf shunt capacitor 22:00 why you need to be very careful when choosing a shunt capacitor 24:35 considerations for capacitor shunts If you wish to consider the shunt capacitor route, I would suggest 10nf X1 Y1 (or X1 Y2) mains class cap and a value no greater than 100nf, as you will start to need to consider a safety bleed down resistor to dissipate any residual voltage in the capacitor, as it will become a potential shock hazard if you don't. I believe the value stated is 200nf or greater, which is sighted in the UK regulations but cannot recollect precisely. Apparently it is listed in section 559.7 but, as I do not have a copy of the current regulations, I cannot confirm this. Here is an UK amazon affiliate link for a pack of 10x 10nf caps: amzn.to/3vIdFiR As described, the location where the shunt is fitted is critical as well as the shrouding of any exposed conductors within a suitable mains rated enclosure, such as the light fitting or pendant enclosure. previous video:    • Curious demo of a glowing LED, even w...   If the content was useful to you please subscribe:    / @robertwilliams8032   Credit to Davinci Resolve 16 for the free editor
