One way to thread something through a tube is to blow or suck it through, same as passing optical fiber and other flexible cables through conduit.

You could probably blow it through with a little compressed air. Poke the first few mm into the glass tube then pass compressed air through the tube. The drop in pressure inside would allow the higher pressure outside to push the filament through utilising Bernoulli's principal. A bit like those "magic" pipe toys with the string loop.

[@RFC3514]

25:11 - Or connect a suction tube to one end, probably faster than passing a wire through it, and air friction is probably enough to pull the filament.

the flexible filaments would be great for mini "neon" signs.

[@markp5726]

You can find a bunch of fairly similar bulbs if you do an image search for "aray flexible filament led lamp" or "art loop flexible filament led lamp". As for getting the filament through the tube, I suspect they use compressed air or vacuum. Another option would be a low-friction (teflon?) plastic tube slipped over the filament, then slip the assembly into the glass and finally pull the low-friction tube out.

[@briannebeker2119]

I have a box of 20 LED bulbs I bought for about $20, fail after about a year or so. I took one apart to see why it failed. I found that the current regulator fails and takes some on the LEDs with it while others survive. I re purposed some the remaining LEDs to make a jack-o lantern light using a couple of lithium cells. While this was kind of useful it does not negate the fact that the circuit is very short lived due to the constant heat the regulator has to deal with.

You can see at the first curve of the glass from the base that the interior diameter is larger than the diameter of the filament. I suspect it is actually fairly easy to get the filament through with a fish wire.

[@BRUXXUS]

Oooh... I wonder how viable it would be to create longer stretches of that flexible filament to be used as a replacement for EL Wire. I mean.... it would require some insane voltages in the way it's currently arranged, but maybe shorter lengths of parallel arrays could help bring the voltages down to something safer to be used as a wearable option? hmmm... Guess it'd be pretty expensive right now, but if they could bring the costs down it would be vastly better than EL wire in almost every way.

Might do some thermal camera mesurments but it runs cooler now. Oh & why 113 ohm, because it was the resistor value I have on hand closest to 100 ohm.

The 240V is the average value of the sinewave. If you multiply it by 1.41 it gives the peak voltage which is what the smoothing capacitor will be charged to.

Clive you're mentioning "traditional dimmers" - as far as I remember, there are 2 generally different types of dimmers and how they work, but I'd love to see a video explaining the differences between those. Also, there are these turn-knob dimmers that sit inside the wall where your light switch is, I remember one being there in the living room of my childhood, and when you dimmed the ceiling lights down with it, it made some sort of buzzing noise. And then there are even electronically/digitally(?) controlled ones, like in those radio controlled power sockets for lighting purposes. Please, make a video about the different types of dimming, how they work and what their advantages and disadvantages are. Maybe even take apart a dimmer switch (possibly even an old rotary one that buzzes below 100%) and show the circuitry, and so on.

I'm guessing the tube was run through with a messenger line and *then* heated and shaped, allowed to cool, and then had the filament pulled through with the line.

When I used to help a guy put wiring through motorcycle frames, he would put a vacuum on where the wires needed to run to, and put construction line in where the wires needed to start, and he'd close every hole he could in the frame, and the vacuum would pull the construction line through the frame and he'd tie the wire to the line and pull it through. I feel like that is probably similar to how they pull the LED string through the glass tube, they probably pull a vacuum on one end and put a line on the other.

11:25 simple linear current regulator 12:20 suggest lower voltage Why would that be, Doesn't it suggest minimal difference to rms for thermal reasons I.e. higher voltage (if you want to call mains high voltage) - but then again 75v is still quite a big difference.

Now, my EE theory knowledge is pretty old and unused, so I might have gotten something wrong here, but shouldn't the rectified & smoothed voltage across the capacitor be 240V/1.41, not 240V*1.41? how do you get >240V DC from a 240V AC supply? or do you put the lamp between 2 phases?

[@bigclivedotcom]

The AC value is the average voltage value of the sinewave. Multiplying it by 1.41 gives the peak value, which is what the capacitor would charge to.

[@FarleyHillBilly]

RMS is the DC heating equivalent of the AC sine wave which varies between zero and a maximum. The peak voltage of the AC is square root 2 (1.414) times the RMS value for a sinewave. About 340v, you can double or triple that with a suitable circuit I've seen a x6 giving 2kv @ 1 Amp to power a 2x 4CX250 linear amp. See en.wikipedia.org/wiki/Root_mean_square

Vacuum on far side, feed thru with a little cornstarch or mica powder which is vacuumed out and reclaimed? Neat circuit, and neat execution. I'll be looking for one on the 120v market. Edit - I looked thru ebay and it seems like 240v is it, and the UK is the source for ebay, wherever they come from originally. I'm thinking a 2 diode/2 cap doubler circuit hack. That would net about 338vdc max. Looks like DC would be ok with the circuit, might have to back off on the current sense resistor to dim it back down due to the duty cycle change. Careful 2nd stage cap sizing might work too, if small enough to "run out" at the right point. Could be a fun evening hack. It's going to cost $9 us for the bulb, but it's worth it.
