They will learn when they turn 7

​@@RS-Amsterdam most don't survive that long

@@RS-Amsterdam 🤣🤣🤣

They work in factories illuminated using the same leds they produce. Originally they were top quality stuff, but when the first one failed it caused an unstoppable chain reaction, the lucky ones are working with candles now.

Yes, the 2 minuets of training seem to have been completely waisted.

Free fireworks from the Chinese Communist Party. Coming to an ocean near you?

They are - from my experience. I have had no failures and have not had to buy a bulb for replacement in years.

I live in a old, 6-store apartment building. The staircase was lit with incandescent lamps that now have been replaced with E27 led bulbs. Unsurprisingly, the landlord buys the cheapest they can find; a single bulb rarely lasts more than a couple of months. When covid restrictions hit I got annoyed by constant "blackouts" and fitted the fixture from my floor with a German brand bulb. It has been going ever since. The "cheap" bulbs are a total scam 😆

@@MLX1401 I too was a landlord - I replaced all the incandescet bulbs in both my buildings because I knew the tenants could not afford to. The compact flourescents I bought were disappointing - they were fragile and did not last as long as advertised. As they failed I replaced them with LEDs which were at that time getting cheaper and better. I left LEDs with tenants whose compact flourescents had survived. They (the LED's) never failed.

@@Onequietvoice Nice to hear that ☺Indeed led bulbs are way better than CFLs, and generally do last a long time! My point was, that if the intent is to save money, cheap bulbs (like shown here on this video) are a poor choice as they're made to fail and need to be constantly replaced.

Agreed - just sharing my experience.@@MLX1401

Non-dimmable LED lamps are the worst.

Absolutely. I know that's the name of the game -- cost cutting. But there should be a 'best practices' level that they're not supposed to go below, because it is dangerous to either the life of the product (eg. 'Planned Obsolescence'...don't get me started on that one...) or to humans or pets. Whoever made the decision to import that shoddy work into the UK should be told about it. If it has an agency's name stamped on it, contact them. For example, "UL" might mean 'Underwriters Laboratories'. They can put pressure on the manufacturers to improve their standards, or they can let the government know to disallow it when it comes in through customs. Too many people would settle for an increased risk of a fire hazard if it just means that they can get their bulb for 30% cheaper. And fires spread to responsible people too. So it becomes an issue that needs to be addressed, rather than this 'buyer beware' mentality.

I don't see any safety issue, it's all well enclosed. Definitely going to potentially reduce product lifetime though

@@paulblitz Yeah until it's time to replace it. Hope you got the mains fuse open.

They usualy also just put a Qc sticker on it and call it a day usualy

That'll be the IKEA Lamps. kzfaq.info/get/bejne/g5ehl8WXyNvNhnU.html

May be Dubai lights should be the standard "everywhere"!

Is the chinese way. The irony is that in the long run it ends up being more expensive uses more resources and produces so much e-waste.

I've recently been reminded of the same thing with clocks. We've had quite cheap clock chips with accuracy far beyond anything a normal user needs, you'll almost certainly have a power outage or just accidentally unplug it before it drifts by a measurable amount. But do we see those in basically any consumer clocks? Nope. All still the cheapest possible oscillators and they drift by far too much.

@@teresashinkansen9402 Yes the evil Chinese brainwashed all the consumers into picking the $1.95 bulb over the $2 bulb on the shelf, no blame on the consumer at all, zero, nada.

A "blob chip" covered with clear goop?

​@@Scodiddlyi can imagine clear COB led strips being one of the first uses

yeah it is pretty amazing. i can remember when they banned regular light bulbs in the eu and it was a real problem as the old energy saving lamps were just toxic trash and leds were just flickery and unpleasant... and then leds just became good and the problem was solved. kinda worried though this is beeing misinterpreted by some as a surefire way of how electric cars are gonna go...just pretty sure banning stuff and getting a miracle isnt going to happen again

@scodiddly... Good idea. Quicker assembly too.

You already get led drivers with the built in bridge rectifier and the buck regulator all in one package. 2 pins for mains, 2 for the capacitor and then 2 for the coil and sense resistor. Only problem is it is a SO8 package, with the mains inputs 0.8mm apart

My local Dollar Tree still stocks LED bulbs, though only in 60w eq A19 and BR30 and 40w eq G30 and C17). I haven't bought one from them in a while, I may get one now just to see how bad they've gotten, especially now that incandescent bulbs are fully banned in the USA. My local 99 Cent store also has LEDs, including 100w eq LEDs for only $2 each.

Soon enough they will go with a fake fusible resistor, with a regular 0.25W film resistor in the shrink sleeve. After all, got to save that 0.1c cost between fusible and non fusible paint.

Shhh dont give them any ideas!!

@@SeanBZA i have a cheapo usb 'charger' that has no form of fuse on the mains input at all, apart from the thin wires going to the plug pins,, theres a place on the pcb for a fuse but not fitted, linked across 😁

@@SeanBZA Or they'll just do what the cheap power adaptor manufacturers do and put a thin, squiggly PCB trace between the incoming line connection and the circuit. That way, they shave an entire component off the BOM.

@@ben-- Cheaper is to simply use thinner wire, 3 strands will act like a fuse anyway, saving precious copper on the PCB, and also saving on that very expensive wire as well, as you cut the copper cost to a quarter.

To what?

@@manolisgledsodakis873 I suppose "decent GE ones to boot". Hahahaha

The simplistic capacitive dropper design with no smoothing capacitor was such a nice low cost idea, it was even dimmable as there was no counteracting regulator . It had a bad power factor though, but getting the LED count near maximum would improve that while allowing a cheaper capacitor . The fusible resistor would need to be replaced by an NTC or induction inrush limiter .

@@johndododoe1411maybe the chips have become cheaper than suitably rated capacitors, now... of course if the chip fails short, 350v ish dc shoved into a line of leds with no current limiting apart from hopefully a fuse or fusible resistor, something will go bang well ... maybe 'cause the power factor was poor, regulations have banned them? like its now almost impossible to get 'plug sized' and even small 'brick' linear psus due to 'energy inefficiency' .. i heard the EU banned them ...

With everything on subscription, and relying on "cloud" servers that are shut off after a few years, bricking entire product lines.

its already coming harder to get traditional wire ended components , many newer chips only available in smt packages although can sometimes get smd to dil adaptor pcbs

The low price and the unknown brand is your warning.

Where it says "Made in China" ?

@@idjtoal Good quality brands such as Phillips are made in China.

Fortunately there's not much left to cut off

Already exists.

@@stalkerfromvoronezh4493 earlier leds lamps did use this idea and worked ok, just they had poor power factor, maybe they got 'banned' because of this?

The older LED bulbs were more reliable than recent ones.

I've featured a few of the intelligent bulbs.

Table in digs while traveling with work.

CE marking is a self-certification (i.e. the manufacturer saying "trust me bro"), so it's not a guarantee of anything these days. You must look only for actual electrical certification done from third parties and hope the manufacturer didn't just print the symbol on the box/product, as chinese manufacturers often do

I thought ukca was just rebadged ce mark

Actually they have been around for a very long time, However like most companies the build quality has gone down the toilet recently.

Maxim used to make reasonable cost and reasonable quality filament lamps.

@@Mark1024MAK let's be fair though, it's pretty hard to fuck up a filament lamp

@@phonotical - not having a gas tight seal makes the illumination “interesting” for a few seconds… 🤣 Also, it’s been known before for the weld that attaches the filament to the support and supply wires not to be properly done, resulting in the filament falling off… Although both of these faults were seen in other manufacturers lamps.

@user-dl6pn9kp8m with machinery to match!

no emi emission would be very difficult as for best power efficiency it'd have to be a switching regulator , low temperature also difficult as watts are watts, all these would make it extremely expensive and not a viable business if people only buy it once!

@@andygozzo72 harsh reality spoils my fun daydream again. Fair points though.

The best bulbs are the ones you hack to reduce their power and extend their life.

It's a cheap brand here.

I know about several people who lave 1980s fluorescent tubes in 1960s fixtures wtill working. They will outlive any cheap chinese lamp made these days.

They are. They've genuinely engineered them to fail fast.

Many people in Central and Eastern European countries have 1980s fluorescent tubes in 1960s fixtures still working. As long as I can but fluorescent lamps I will not replace them with LED.

A lot of fluorescent lamps can have over 80 lm/W, some special ones probably more. LEDs are around 100 lm/W. The efficiency of the low pressure sodium lamps is still unbeatable, with some lab samples being around 300 lm/W.

@@mernokimuvek the theoritical limit of yellow phosphor led efficiency is 250 lumen per watt, 300 lumen per watt is just crazy

@@GERALD_786 I was talking about low pressure sodium lamps, not LEDs.

@@mernokimuvek i know, im just saying that lps is far more efficient than the limit of led efficiency

I wouldn't be surprised if it suddenly diode!

According to the sub titles, it has a bridge wrecked in fire!

We are not LED anywhere! Life hangs but by a filament of imagination.

That is likely to happen. They have re-alighed the efficiency bands. Under the old bands this would have been an A+ efficiency, under the new bands it is probably about a D.

@@katrinabryce "D" is pretty good rating for LEDs, lesser LEDs are usually rated "F", where "G" is the bottom of the scale.

@@JendaLinda someone needs to ban those that do the banning😉

@@andygozzo72 True. They have apparently nothing better to do.

Keep in mind that the capacitor will hold a charge for a long time once the resistor is removed.

doesnt always mean they'll last , google 'capacitor plague', and they're miniaturising them too far

@@andygozzo72 DiodeGoneWild opened a brand new power supply which has reused scrap capacitors and they even tried to hide the dents with wax and put a new fake heat shrink over it.

@@mernokimuvek 😲 sacre merde! that said i do have a plug type 12v psu that looks if its been 'repurposed' as it has input and output wires cut off and the new ones soldered to pads on the track side 😲 or maybe the cutoffs were for testing?

@@andygozzo72 Dont use cheap noname brand chinese power supplies including phone chargers. Sometimes there is no isolation except the enamel on the magnet wire between primary and secondary of the transformer. You have a few micrometers of enamel separating the output from mains input.

@@mernokimuvek i know, thing is not everyone can afford the 'top' brand ones, the ones sold 'fairly low price' by UK shops are usually ok, luckily,
