So it's just a string of filament lamps in series is it? Well there's a bit more to it than that. This video covers the science behind the series strings, fuse lamp, dead-lamp bypass feature and why your lights sometimes seem to pulse really brightly when first powered up.
Where’s the video where he put leds in and added a rectifier mentioned at the end of the video?
I have these in my school but the bulbs, they all died 😢
oh no, mains voltage got to his mic
Horrible fuzz noise in the audio clipping…. Not enjoyable. Might want to re-do this one.
In the US the "fuse" bulb you speak of is the flasher bulb. Or that's what I always thought it was. oh on further research i'm wrong, Clive is right, the flasher bulb is identified by a bi metallic innards and maybe a red tip.
Oh man, I learned the hard way that Christmas lights can pack a hell of a wallop. I was swapping out a broken bulb on a set attached to a switched outlet in my carport. Turn out the butthole who installed the outlet switched the neutral side, not the live. When I grabbed the filament leads on that broken bulb, I got a nice healthy 125v jumpstart.
wow the lights that was flickering was scary spooky . ghost electric
Very, very educational.
I know this is an old video, but I'd love your input on this. I had an electronics teacher who said that lightbulbs ONLY burn out when being switched, and said a friend's of his had a bulb in his barn run for several years before burning out when somebody toggled the switch. How true is this?
Hey, congratulations on a thorough go-round on xmas lights. You are the only person I've ever encountered who knew about the little wire-wrap at the base of the filament, never mind what it's for and how it works.
Interesting details of lamp construction.
I miss the old days of screw in bulbs – when it was a lot easier to get spare bulbs ….20 lights in a string made sense 20 x 12v volts = 240 …..then the manufacturers realised that consumers often needed more than 1 set for a tree – so they made the larger 40 light sets …….and then to confuse everyone PIFCO started making sets of 35 meaning the voltages of the spare bulbs all varied . ….. then push in bulbs started and so many different types of fitting – impossible to get the right bulbs ……. I do like the new LED warm white bulbs but LED lights are very plain when you compare them to pretty light holders in the old style screw-in sets …. incandescent bulbs give a much more magical Christmassy atmosphere than led …just my opinion .
"death…." that echoes in my soul….
Very interesting. Can't wait to break out this new knowledge next Christmas.
