12V LED filament lamp video disaster.

[@JuliaMono]

This is not disaster at all... this is a perfect example how to do it right. I don't learn from everything going right, I learn a ton from everything going wrong. You are a hero for not cutting the video to make things smooth. :) Thanks.

[@andymouse]

This actually ranks as one of your best LED bulb vids (in my humble opinion) purely and simply because it didn't all go to plan, after all, there is finite amount of stuff you can say about these bulbs and their power supply's. Beautifully recovered and explained once you regained your composure. Quite delightful, old chap!

I'll save you the trouble... you get the brightness of a million leds for 10th of a second and then complete darkness, and a burning plastic smell... or so another youtube video doing exactly that indicated... a melted puddle of filaments was to be found at the bottom of the bottom of the bulb... although that was with only 110V! xD

After also watching Julian's video, I thought I would take one apart. Just like you I did exactly the same thing. Also took me 20 mins or so to work out what was going on. You could imagine the pain I was going through, screaming at you all the way from New Zealand with the problem, the 20 minuets seamed more like hours!! So pleased it also took YOU the same time to work it out!! It first I thought they were the series type that needed 70+ volts per strip to light and used a boost converter. After I got to 100 volts I thought I better take another look!!

There's quite a few different voltage lamps from selv up to full mains on a standard e27... the 110v ones often cause hilarity as they look just like a standard 240v GS lamp but they don't like the extra juice... the 12v ones that look like a standard incandescent lamp could be quite amusing.

[@Microwave_Dave]

I ditched all of my cheapie M830Bs after they wasted hours and caused days worth of grief. Out of four meters (which looked similar outside but had very different internal PCBs) three had dry solder joints in the probe sockets that weren't immediately noticeable. Readings fluctuated wildly depending on the temperature, current, and if the leads were nudged slightly. Resoldering helped but cheap plating on the sockets meant readings changed if you rotated the leads. Two had issues where tapping the range wheel altered readings as you found at 6:10. One day I was nearly tearing my hair out diagnosing a circuit where the same wire measured as 12V in the engine bay but only 2V inside my car. The LCD wasn't tight against the circuit board, and the rise in temperature inside the hot car made the 1 disappear. It was reading 12V all along. Tightening the screws holding the LCD in place helped but soon stripped threads so the problem returned and ruined another day. One of them changed readings if you squeezed the case. Never did figure that one out, but probably a combination of everything above. The fourth one seemed the best of the lot but the range pointer was ambiguous. It had a very defined arrow which at first glance appeared to point to the selected range. But it also had a small dimple (like your meter) at the other end which was the REAL indicator, not easily visible in dim light. Forgot about the weird knob one day, tried measuring battery voltage in current mode and BANG... blew the arse out of it and burnt my hand. I made the decision to scrap them all, saving myself a lot of grief. Time and sanity scarce these days and I'd rather waste neither! I've since bought four small Aneng multimeters to inhabit my scattered toolboxes, which seem far better in every way than the M830Bs. They even have buzzers, backlights and temperature probes.

[@Microwave_Dave]

Before I forget, I should mention that most of my store-bought alligator clip jumper leads were poorly crimped. Some weren't cheap either, it didn't just affect the bargain basement leads. Most had wires that were too thin to reliably crimp in the alligator clips, so to "solve" this issue the manufacturers simply folded the wire back over the insulation and crimped the insulation in with the wire. I discovered this when some wires fell out of the clips while measuring higher currents than usual. The high current, high resistance connection softened the insulation causing the wire to slide out of the clip. After that incident, spent a few hours repairing or replacing dodgy crimps and wires on every lead I could find.

[@Anvilshock]

Are those Aneng multimeters hard-switched? Because boy is that auto-off "feature" of their 8000 series ever so annoying!!

[@needforsuv]

I got a generic one from ebay and works fine. Got it 2 years ago for justt over 3 and a 1/4 australian dollars delivered to australia

[@PunakiviAddikti]

Yeah, a reliable meter is mandatory.

[@Mark1024MAK]

Microwave Dave - for this very reason, I only use test leads with either 4mm plugs and then fit a croc clip that has a 4mm integrated socket, or I make my own leads up and solder croc clips on myself. And yes, one of the problems with cheap multimeters is the unreliability of the contacts in the range selector. This is nothing new, it also affected the cheap moving coil designs available in the past as well. And almost certainly still affects any current cheap moving coil designs. The lack of quality on the 4mm sockets, or other smaller sized connectors is also annoying. For all these reasons, I restrict the usage of the cheap meters that I have to use on circuits operating at no more than 20V. If I get a result/reading that I don’t expect, I double check by using a much better multimeter in parallel 😉.

[@henningerhenningstone691]

Thanks so much for this video! We've ALL had those days where one little thing seems to be completely halting the whole project until we figure out that tiny detail (like bad solder joints). To all the people thinking "Well, that's why you should be more careful!", half of tinkering with things is going to involve somehow forcing your way into something, be it physically or digitally, so that's not really an option all the time. (Although I would have just taken a soldering iron to the ends of those strips and tried to resolder them at that point, maybe add a touch of flux first to re-bind them - or did you try that to no avail? I uh... I'm clumsy, so I end up doing patch-repairs like that at times. *cough*)

Home Depot in the States is selling "EcoSmart Clear Filament Vintage Style LED Light Bulb" in clear and frosted glass but cram all the capacitors and resistors in the space of the Edison screw and between the screw and the capacitors is a layer of plastic. The result is that they get very very hot and die after only a few months/weeks of use. When the first start to die they flicker within the first ten minutes of being turned on for a couple weeks and then one day they don't turn on. I took a couple of failed ones apart and all of them reeked and the capacitors were bulging; one had electrolytic all over inside.

One, I repeat one teacher in the whole of my school was such a attentive teacher that I never turned homework in due to a very long story, he passed me every year because he knew I was understanding his class well enough that home work was a formality and the tests were what counted. Practicality is more important than formality, paperwork for paperwork's sake is rubbish and has been since bureaucracy gained any traction so since the dawn of modern man. I think we can agree on that point after all the rants you've gone on about certain "Policy Implementation" on the electric guidelines in the UK, Scotland really does seem to produce " Practical, Peppery and proud" people glad I can confirm half my blood comes from the Highlands.

That nonsense really got going with PCs. They used a serial connector for a parallel port, a joystick connector for a serial port, and an Ethernet connector for a joystick port and for an audio port. I was just waiting for them to use a sub-D connector for the main input too!

[@raphidae]

In the PA audio world some people started using XLR (usually line/mic) for speakers and later power as well (so they could interchange cables). If you know what you're doing and label everything correctly it might work, but I think so much stuff got blown up that it wasn't worth the savings on cables for most. When SpeakON came out it was often used for power as well because it has connector locking. Though if you didn't use bi-amping over a single cable you could use 1&2 for speakers and 3&4 for power (but no cable saving/flexibility that way). Eventually they created PowerCON, but lots of people still have SpeakON PowerCON pigtails or converters in the random box so they can use whatever cable they have at hand in a pinch. Connection standards have always been a mess.

I was curious about the design of the circuit thanks. Mainly as these bulbs seem to be on the 3 dollar range. I guess this is due to the low manufactured volumes compared to the 1 dollar 220 bulbs. I am also hoping these 12v filament bulbs can survive longer than their 220v counterparts....

[@chrisw1462]

It occurs to me that the random LED spacing might be on purpose. With regular spacing, if the lens is faceted at all, you may end up with a repeating pattern of light on a wall. With random spacing the pattern from one bulb would be random (and likely blamed on the glass). More than one bulb and any pattern would barely be visible at all.

The bulb is shaped so because it's made to look like an Edison bulb.

That bulb is very deceptively called an LED (light emitting diode). There isn't anything diodec about it The emitting filament has no diode effect. The diode he mentioned in the circuit board he pulled from the base If you removed the plastic casing from around the internal filament will emit a very bright light...that would be a true light emitting diode. Those crazy readings from the FILAMENT is an incandescent effect ...not a diode at all! Bravo! The technician in this film has got it! What it is actually named is a "Light Emitting Wafer" with a filament core. Only about half as efficient as a true LED bulb.

[@richardnankivell6451]

The XL6001 chip on the circuit board is a constant current (not voltage) regulator. Varying voltage from a power supply to the LED's probably will destroy them. Having said that, my advice is to go to your favorite retailer and buy a new globe. They're cheap and actually solve the problem. Best of all, you don't need to pull a new one apart!

[@ehsnils]

Having the filaments in series is also a goo way to ensure that they can sell more of them since only one failed filament is enough for the vendor to make a new sale. One thing that is also bugging me is that when you look at the packaging then it's listed as a lifetime of an LED lamp being like 40000 hours, but that's only the case if it's on for a limited time each day and even the "off" time is included in those 40000 hours.

Richard Andrews ironically I was too expecting it.. come on Clive! Do a cheap LED pop! I like seeing the cheap LEDs release their pixies.

[@zacharysandberg]

Anyone heard from Photonic lately?

[@NoisyPlaces]

Zachary Sandberg last video he was not his usual self and was suggesting that he may use the big boys power supply in a terminal fashion. Nothing seen since.

[@zacharysandberg]

NoisyPlaces Yeah, I remember his last video. Hope he’s doing alright.

[@Rych]

@@zacharysandberg I hope he's doing well too, that last video he did was a tough watch

The mode switch in the 830b meters does play up, the contacts are cheap. Rotate the switch a few times before use.

[@tubastuff]

I've got a couple of those--same issue. I wonder if some Cool-Amp might help that, or maybe some dielectric grease on the contacts to keep oxidation at bay...

“There’s your problem lady!” Classic

[@tomgeorge3726]

The minute you took the lamp apart and cut the LED wires, the service tech in me SCREAMED, "You should have powered the assembly back up and measured the voltage at the LEDs". Then that would have made for a dull Clive video, and we can't have that!!!!! Only sad thing was NO SMOKE....

[@znrctrnn]

I get excited when I see LED filament lamp bulbs.

Eating buffalo wings and watching BigClive ... Life's good

[@bazzarr]

Clive, it always makes me sad when you tear apart stuff that I want to play with :(

[@bigclivedotcom]

Most of it gets put back together, but not this one. One of the main purposes of the channel is me taking things to bits so you don't have to do it to yours.

[@l3p3]

It would be nice to see you explaining the more complicated stuff like the block diagrams and op-amps on the end of each video, so people who don't have any interest in these kind of things can stop the video while people like me can maybe learn a little bit off your knowledge. Or is it maybe too complicated for you as well? To me, it would be very nice to learn a bit about "analog programming".

Constant power driver for the win :) Also known as negative resistance in more polite circles. 🤔

[@phinok.m.628]

Ah don't worry about it. I don't know about the others. But personally I think in a way it feel more natural if things go wrong every now and then. I mean, that's just life. I think most people who have worked with electronics have had at least one time where nothing worked as expected, to the point where you start questioning your sanity. P.S. No eBay keywords?

[@highvoltagemayhem3345]

On our ship everything is 450v, I would love to screw one of these in there and see what kind of a mess we get...lol. Thanks for another great video.

[@JasperJanssen]

Blown rectifier, exploded cap, blown driver chip. Not much more drama in all likelihood.

[@jackwalker6239]

Hi Clive, do you still use a phone to shoot your videos? If so which one as my new one the one you advised me about the 9v then 5v USB charging on it the other day, I'm absolutely blown away with the quality of video and this isn't even a top of the range a P20 lite.
