my work let me take apart the 480v LEDs they got for their warehouse after they died. The bulbs claimed a 10-year life but died after 2-4 years. When I got them apart, I found the capacitors to be the issue. Checking their datasheet, I found that they were only guaranteed for 2 years of life. How can a company claim a lifetime 5 times longer than the lifetime of their parts? (and no, the capacitors were not oversized or underpowered in any way)

[@nzcym]

MTBF is heavily depending on the environment temperature. If the manufacturer adding sufficient active cooling equipment such as heat-pipe and long lasting cool fan, the life span should be increased accordingly; of course, so does the price tag.

[@sbrunner1234]

I have seen that claim being made on operating time, not actual past time. Then there will be an assumption on the time of operation per day.

[@artforz]

Electrolytic capacitors can be up-rated by about a factor of 2 for every 10C they are below nominal max operating temp. (note: this has to include internal heating from ripple current). That's why a 20000h 85C and a 5000h 105C rated capacitor offer pretty much the same effective lifetime at sane operating conditions. At least Nippon Chemicon and Panasonic have appnotes explaining this in detail.

[@deang5622]

​​​​@@nzcymThat's true for the LED chip where the device is a semiconductor and the length of its life is strongly dependent on operating temperature. That isn't the case, generally for capacitors. The 25,000 hour typical life that is quoted for LED lights is typically the life time of the LED chips and is stated on the data sheet by the manufacturer of the LED chips. But this is the life time of the chip if the LED operating temperature is kept within the limits indicated by the LED chip manufacturer. Then the light bulb manufacturers put the chips on to a board and put into a bulb, then the bulb is placed into a confined space into a luminare without sufficient cooling and that 25,000 hour life drops significantly. When you look at the cooling features on an LED bulb that conforms to a standard replaceable bulb type, with bayonet or Edison screw thread, they typically just have a few cooling fins along the body of the bulb. It's a pathetic amount of cooling. Why would the industry want to fix that? Bulbs failing results in repeat business.

[@Demo12345]

One thing about the incandescent bulb in your one lamp, that bulb has survived for so many years because it's been turned on and left on. The biggest thing that will kill that type of bulb is power cycling. It stresses the filament every time you cycle it on and off, so if it's turned on and off enough times it WILL die. Though if it's left in a place like what you were showing where it was able to be left on and never change its state of being on or off then the stresses on it are limited.

[@TheExileFox]

It saves the bulb a lot of stress if you have a soft-start circuit.

[@cassianomartin2699]

​@@TheExileFoxyes, bulbs with dimming circuit survives a long time

[@zedcarr6128]

True. Tungsten has a positive temperature coefficient, so the resistance is lower when cold. When switched on, if the AC cycle is near or at the peak voltage, 325 Volts here in the UK, then because the filament is cold, and has a lower resistance, the peak current blows the filament and makes that characteristic ''chink'' sound when it does. As an electronics geek, I like to call incandescent lamps, directly heated monodes. 😊

[@alex_stanley]

The incandescent floods in my kitchen are original from when the house was built in 1994. They are 130v bulbs instead of the more common 120v, and they have always been on a dimmer switch where the light has to be dimmed up to full power. When tungsten filaments are never stressed, they last forever.

[@joewoodchuck3824]

You are correct. I saw a slo mo video years ago that showed a clear light bulb filament being violently whipped around in the first few alternations of current flow. On that basis, DC would seem to be gentler upon startup due to a single filament movement with the onset of current flow instead of the multiple alternations of AC current. Not that it's practical to do so, but still interesting.

[@johanslabbert2869]

Why do they fail (prematurely compared to expectations) ? It’s simple. Most LED bulbs are severely price constrained. By using fewer LEDs it’s cheaper to make but to get a competitive light output those LEDs needs to be driven to the edge of their existence. So they get hot, and either burn themselves out or the heat kills adjacent components. The thing is, we cannot realistically complain about planned obsolescence while at the same time demanding ever cheaper consumer electronics. Good quality LED bulbs do exist but they typically cost around 5 times more than the cheapest ones. And the good ones do last long. Incandescent bulbs went through a similar phase, for a while one could buy incredibly cheap horrendously badly made bulbs that would sometimes break on the trip home. But when well made, they too can last decades. I have some incandescent lightbulbs still in use since the late 80’s. Also, fight me on this but nothing beats the colour rendering of a good incandescent lightbulb. The 200W versions I have are pretty decent at being subtle space heaters too. (And especially effective at melting modern plastic light fixtures 😅) The best hack* for cheap LED bulbs is to trim the current sensing resistors to run the bulb at a lower wattage / current. Aim for around 10mA per LED and they should live a long happy life. *Credit to BigClive for this one. See his channel for more details / how to.

[@Lagittaja]

There's no need to fight you on the color rendering index. Incandescent is obviously best (100 CRI and good R9) because it's just a black body radiator. LED's however can be good. You just need to pay for it. There are many options with 90+ CRI or 95+ CRI or even 98+ CRI. The CRI rating however is problematic. The CRI rating only looks at the R1 through R8 colors which are pale colors. Previously mentioned R9 is a deeper red. And if a light has a poor R9 color rendition, skin colors for example look ghastly. The extended CRI looks at R9-R14 colors as well but CRI Ra value is based on R1-R8 performance. There is IES TM-30-18 as well and CQS etc. but this needs wider industry support/push and we'd need consumers and professionals to ask for better lighting. It's just unfortunate that the vast majority of people don't care so we get sub par products.

[@abhimaanmayadam5713]

Also most people shove any bulb into an enclosed fixture. I need to tear one of those apart

[@mrofinUtortxoF]

LEDs, even cheap ones, don't usually fail on their own. In most cases the issue with this type of lamps is a small (or non-existent) heatsink or a cheap power supply. Just look at third lamp - it has everything it needs, and it serves for years. the other ones may serve a year or two before dropping brightness and eventually failing. LEDs are also better because you can purchase ones with high CRI and almost any color temperature you want, even the one of incandescent lightbulbs. But why would you.

[@1pcfred]

10mA per LED is pretty low. Even ancient LEDS could tolerate more current than that. I would think double that is still within the realm of reason. A modern blue LED is more along the lines of 30 mA rated. It'll light up at 10 mA but it's not going to be particularly bright. Another thing you can do is vent the bulbs. If you can reduce the heat you will increase the life. Every 10 degrees doubles the life. Heat is that significant a factor. They should stop trying to make light bulbs like light bulbs. Come up with a design that manages the heat better. Clearly manufacturers don't care and are just interested in selling product. They should make lamps with built in PSUs. Maybe the Edison screw base isn't the way to fly today? The packaging is all wrong. Stuffing LEDs into a housing designed for incandescent filament is just dumb.

[@Lagittaja]

@@1pcfred Well, that depends on the LED. I guess better suggestion would be to look at the current they're running the LED's at and then perhaps halving that or something. In a previous comment I hinted at the LED I/Vf curve. As the current increases, the forward voltage increases as well. LED power does not increase linearly. Similarly, as you increase the LED current, the light output does not increase linearly. Just as a simple example, manufacturer might run 50% more current through the LED's, only to gain let's say 25% more light output. But the power consumed will increase by more than 50%! So, if you reduce the current, the drive circuit will have much easier time as the power load decreases more than the current or the light output does and the LED's as well will be much happier. Obviously the 2835 or whatever size LED's are used in bulbs have smaller differences than the above rather extreme examples but the principle applies. Just for reference, I looked up LM281B LED specifications and it's rated for 150mA at 57-61lm. So you'd need about 13-14 of these for an 800lm bulb. Looking at the Vf curve, and guesstimating, at 150mA the forward voltage is roughly 3.15V. Halving the current to 75mA, the forward voltage drops to, let's say 2.95V. While the luminous flux drops from 100% to, I don't know, let's say 58%. Current drops from 100% to 50%, power drops to 47% and luminous flux drops to 58%. See what I mean? But this is just going from the rated current (150mA) downwards. The max current on that specific LED is just 160mA. There are other LED's which have a much wider range between the rated current and the max current. If you do the same calculation for an LED that's driven hard vs driven at the rated current, the difference is only going to increase.

It was soft enough to gouge deeply from your screwdriver tip, but all that leverage didn't stove in the metal surrounding it at all (like the same thickness aluminum probably would). I've seen it before in other LED lights: the zinc is much better than no metal heat sink, and explain better why that bulb was oddly heavy. A large, thin sheet of aluminum like you found in that other bulb is arguably worse, made so thin to save money the heat travels poorly to its outer edges.

[@boxchain]

I agree. Zinc is cheap partly because of its very low melting point, much less heat required to cast it. The greater mass means a higher heat capacity, and it's larger, so more area to shed the heat from.

Meanwhile, one of my newer ecosmart bulbs died in just a few years. A capacitor blew its load, there was electrolyte all over inside of the bulb. At least it didn't fail catastrophically, unlike the ancient CFL in my garage, in which the electronics melted its casing.

Like you said at the end of the video, if you treat the LEDs well it can last a lifetime. Did you know that LEDs degrade over time due stress by over powering the LEDs? Mostly not a problem of your eyesight when you discover you can't read something, it is just degradation of the LEDs. Most manufacturers include 50% degradation as still usable in the warranty specification. Second, we always talk about LED but it is actually a LED package, there are mostly more than one LEDs inside a package. I have seen a tiny package with 12 LEDs inside. That is why the LED package can get so bright and hot because they are packed so close together, it is almost impossible to dissipate all of the heat especially when overdriven. Inside a closed enclosure, it is even worse. That is why the bulbs fail sooner, heat is the enemy of all kind of electronics. What I did with most of my LED lighting is to reduce the current, remove the (excessive) heat. This really helps. Reducing the current effects the amount of light it can produce a little but it is worth to do so because there is a less heat, low degradation, longer lifetime and lower power consumption. That is a win!

[@Ni5ei]

The whole concept of LED lighting for home use is flawed. Every frackin' bulb has to have electronics inside since all they'te thinking about is backward compatibility. When halogen lighting became popular, the conversion to low voltage was done outside the lamp, like it should. Replacing a popped bulb only meant replacing the actual lamp. Way cheaper and 100 times more environment friendly. I scavenge the local street lighting company once a week and even the retrofits for street lighting have this "all in one" approach. Many broken lamps just have the electronics fail prematurely because of getting too hot, bad components and moisture getting in. Newly built houses shoud have a separate circuit for low voltage lighting so all the lamp needs to contain are LED's and resistors.

[@mfbfreak]

If you start requiring a low voltage circuit in houses, you can expect that the power supplies that get installed will be very unreliable. Landlord's specials. And replacing those every 2 or 3 years, can be just as expensive as swapping out a 2 euro LED bulb, because the power supply will be a "Special Appliance" that is sold at a premium, or is located in such a place that your average homeowner gets unsure about replacing it themselves. Your idea can absolutely work, though with switching regulators in the LED bulbs instead of resistors. Switching regulators can deal with some voltage drop over the wiring ensuring that the brightness of all LED lamps will be equal, and they will run a whole lot cooler than a resistor driven LED bulb, therefore increasing life span of the LED phosphors. Cost wise it does not matter. Those driver chips and some associated components get you to maybe 45 cents in total, wholesale. I do not exactly know if you save a lot on heat production by running a switcher on low voltage rather than high voltage. But at least you can get rid of the bridge rectifier and filter capacitor, both of which are not uncommon to fail. I think one of the biggest benefits is that you can make the lamp housing out of metal, and use it as a big heat sink, safely. Theoretically you can do it too on mains voltage, but you need an isolation layer that thermally conducts. But in the end, what counts is production cost, and even in the above scenario, corporations only strive for biggest profits with the lowest quality level the market still tolerates. They are not making those lamps for the good of the people, but only for the good of the shareholders.

@@mfbfreak the problem there is what voltage is the DC? Different LED lights require different raw DC voltage. So your house DC supply would have to be the highest necessary value or you would need DC/DC up converters to step it up for the larger lights. You still need either inefficient and heat generating/sensitive dropping/limitting resisters or DC/DC down converters (more efficient & less heat). So you probably do gain some reliability at the lights but you have now created a single point failure at the house lighting circuit supply. If that goes, then you loose all your lighting. You may also introduce more arching at the light switches. Separate lower voltage lines for switches with relays in the fixtures? Not necessarily a bad idea but would really require some serious design and would have to come from either the government or an open-source industry consortium.

I've found that newer LED bulb designs produce a lot less heat, and so far seem to be lasting longer. It's also worth noting it depends on what fixture you put it in. As some fixtures can dissipate the heat well, and some (nipple/boob cheap lamp fixtures) have poor to no heat venting. For incandescent or compact fluorescent bulbs this was fine and did not accelerate their death (except for some CFLs), but boy does it ever accelerate the death of LED bulbs! (if they get hot enough). So kinda wish you had covered the fixtures each were used in more closely, as this detail I'd say is very important.

[@joergsonnenberger6836]

This is exactly the problem. Incandescent bulbs, CFLs and LEDs all have different constraints for long life, but end users rarely care or even know about them. For CFLs, short on/off cycles are a death sentence. For LEDs it is poor heat dissipation more than anything else.

[@spunker88]

The packaging on some cheap LED bulbs will tell you not to use in enclosed fixtures. I had a light fixture that was killing LED bulbs in less than a year and found this to be the issue.

Thank you for the insightful video. I've been repairing led lightstuffs here an there, and I agree that most of them fails because their power supplies failed. Luckily with the proliferation of tech gadgets I've amassed quite a collection of dc adapters with outputs anywhere from 1.9V to 24V, and with them I can usually clip off the supply and just soldered a dc socket. Power supply far away from heat generating component = long life. Second type of failure is the other way around, where they cut costs of the led silicons themselves by using fewer of them and driving them to the edge of oblivion. These usually failed by dimming. I really looked forward to a future where residential solar power is so ubiquitous that HVDC gained a standard in households, something like 48V or 50Vdc. Then all new light installations can simply use buck circuits.

[@kenibnanak5554]

I have had *and have* incandescent bulbs that last decades. At least 4 for some of my older lamps. I tried fluorescent bulbs when they came out a decade or two ago. I bought a Chinese made box of them at Best Buy on sale one day. Installed one by one I watched them stop working over the course of a year. I just swapped them out from the box at first. Then the show stopper. I walked into a room and turned on the overhead light and was met with immediate sputtering, and most worrying, actual smoke and small red sparks falling, coming from the base of the bulb. That ended the life span of fluorescent bulbs from Chine in my house. About a year ago, due primarily to my running out of stored incandescent bulbs I began to use LED bulbs. I have yet to have one last 6 months. I have one in a hall that works sometimes. Luckily it isn't the only light in that hallway. Apparently whenever an alien spacecraft enters or departs our atmosphere it turns on or off. There is no discernible regular interval between turning on and off. Sometimes it turns off for a half hour, sometimes for just 4 or 6 minutes, sometimes for 2 or 3 hours. It is the only LED on that circuit so whatever is happening is either internal to the bulb, or some kind of interference caused by alien space ships crossing the Van Allen Radiation belt or Chinese experimental firing of their Ion cannon. Luckily at an auction I was able to pick up some more incandescent bulbs. My intention is to wait another decade (or two) before again trying LED technology as a cure for darkness. It is pretty obvious here that at the current stage of development any talk about LED lights saving the consumer money is just scammer talk (aka BS) once the cost replacing failed LED light bulbs is factored in. Maybe in a decade there will be reliability improvements, but as a consumer, I will wait and see.

They are rated for 15000 hours of life and I've calculated that as being roughly 2 years of being on 24/7 I have a bulb in a lamp I use in my bedroom which often gets left on for many hours a day sometimes overnight, and its still working today, tho it might have dimmed a bit, but I haven't compared it against a brand new bulb. I personally can be happy with a 5 year lifespan for LED bulbs as I've been using those halogen incandescent before and those only seem to last about 7 months in my experience.

As a contractor, I have installed dozens of outdoor LED motion Sensing flood lights. 3/4 of them have been 120 VAC, and 1/4 of them Solar powered. ALL of the 120 VAC units have failed within 13-15 months of installation, all from the power supply failures of various kinds (just past the warranty expiration). I did post-mortems on all of them and the LED's are all working fine. All of the Solar Powered units are still working, two of them for over 7 years on the same cheap battery. Yeah, the complexity of the conversion electronics have been the downfall on each of the AC units.

Great video! I've always wondered about these. I didn't understand much, but I absolutely agree that 5000K lighting is madness.

LOL - you are very entertaining - but I'd better go waste my time on the good book on the downstairs couch. :) P.S. I just subscribed to you.
