Do not think anybody would notice those failed chains up in the roof, but if you are going to fix easiest to just shotgun all in the chain instead of looking for the failed ones. You casn just see the single off bits in the video, but overall the light output is not much different on your face. Nice to see the protection diodes did the job, just watch with some 6V8 zener diodes is that they often also contain, because they were designed to be a stable voltage reference, that they are in actual fact a 6V2 zener in series with a regular diode, or are 2 6V2 zener chips back to back in the package forming the same thing. This is because 6V2 is around the right voltage for a zener temperature coefficient to be the same as a silicon diode voltage change with temperature, but opposite sign, so as the diode heats up and cools, the voltage is a lot more stable. Had a few that were designed for voltage reference use, which were made like that, though the most common ( and cheapest) zener diodes are just regular diodes, and are basically just a diode. Time to go to Clicks and buy a new Oral B brush, that one would not even work to do tile grout any more, you will get change for R20, and they clean so much better. You saved the church a packet, bet they will ask before nailing in future.
