Lights with non-replaceable bulbs can actually be far better, because they can be designed for their environment. Recessed downlights with built-in LEDs for example can thermally couple the LEDs directly to the metal housing, so the heat can be dissipated into the surrounding air, instead of into the recess.
The only place where this doesn’t happen is in the country of Dubai. Because of national law, lightbulbs sold there are required to have very long lifespans. That’s why there is a world-wide grey market business for taking existing LED lightbulbs apart, snipping off a resistor so that they pull about half the amperage and then putting them back together, and suddenly their lifespan is increased by 10-100x. This is called a “doobie”, after the name of the country. Check out “bigclivedotcom” on YouTube if you want to see this in action.
You will notice this if you buy Philips Ultra Definition bulbs in Dubai, versus the same bulbs sold at the same amount of lumen output from the UK or elsewhere in the world. The “doobie” version has twice as many LED filaments inside, compared to the UK version. Same price, way different life span. Philips is one of the better manufacturers of lightbulbs, and nowhere remotely close to the only one doing this.
With regards to LED light fixtures (ones that don’t allow you to screw in your own bulb), most manufacturers do the same thing. They’re designed to fail early. Who wants light fixture styling that is fifty years old, just because the LED lights inside haven’t failed yet? They want to make you buy new fixtures every couple of years, just like they do for bulbs.
Yes, there are exceptions in both cases. But they are the rare exceptions, not the rule. And if you haven’t studied up on the Phoebus Cartel, you can start with the article on Wikipedia.
Dubai isn't a country. It's a city in the United Arab Emirates.
The Dubai bulb isn't some trick Big Lightbulb doesn't want you to know about, it's an engineering tradeoff: lower current on more filaments gives you higher efficiency and lower temperature but at higher cost and with substantially lower light quality (CRI).
You'll find that after EU energy labeling, there are products available to European consumers that well exceed the specifications of the "Dubai" bulbs. Look for EU energy class A. They often come with a 5-year warranty and rated lifespan of 50000 hours. The "Dubai" bulbs were rated for 25000 hours. You'll also find though that they're substantially more expensive and usually don't have a CRI above 90.
Regarding planned obsolescence, in many cases I can believe that a product will fail earlier than it would if designed for longevity. Rather than planned obsolescence, I believe this is simply a result of being cheap, a consequence of the race to the bottom. If you're buying cheap Chinese fixtures for $10, or cheap Chinese bulbs for $2, you're not going to get a high-quality, long-lasting product.
If you want products that last a long time, buy them and use them properly. If you want bright lights, make sure they're adequately cooled. Consider buying lower-voltage fixtures and bulbs so that you can have a separate power supply and don't put the full ~230V to ~3V conversion in a tiny space.
I learned recently that Dubai is also the name of the emirate. I don’t have a good understanding of the UAE governmental structure, but the Emirates do seem to have their own governments. Maybe it can be thought of as a country in the same way Scotland can be thought of as a country.
There was one time I bought some cheap ones from Amazon, and several of them failed within a few months. There was also an LED bulb in the front porch light (so, outside) that lasted around 10 years, despite being outside and used daily. I had several of that same type and that particular one lasted longer than all of the others, where the others were all inside and not installed upside down. So yeah, it varies.
Regardless of all of that frustration, thank the gods we no longer have to deal with CFL
As far as I'm aware, we've got comparable bulbs available in Canada. We've got the Philips 95 CRI ultra definition bulbs and the ultra efficiency bulbs.
The UltraEfficient bulbs seem better-specced than the Dubai bulbs - the standard A19 of the latter is specced for 6W/600 lumen/25k hours at 80 CRI, while the bulbs I can buy at the drug store here are specced for 5W/810 lumen/50k hours at 80 CRI.
I also have Nanoleafs that I have had for about six years and so far no issues. They run for about 12 hours a day on most days.
I am in BC,CA. I gotta take apart my lights and see what they are.
There's no clean mechanism to control a fan's speed in-band on a normal AC wall switch.
There absolutely is. If you have a fan with a light controlled by separate wall switches, you have two hots running to the fixture. Take one, and leave it unswitched always on to the fixture, and use the second switch (or fan controller) and use it as an input to the controller on the fan. Done.
Unfortunately, I haven't seen this implemented anywhere.
This message brought to you by the hours I've spent annoyed by exactly this misfeature in our new bedroom fan. Fanimation does sell a wall mounted remote that can be wired inline with a switch, so at least there's a single point for master power and a remote you can't lose. Unfortunately, there's a noticeable delay between flipping the switch and the light turning on.
I went through this pain when I bought ceiling fans a few years ago. Various manufacturers offer switches or remotes you can attach to the wall but that take batteries - the options for actual wired switches are slim. I ended up with a few hardwired Big Ass Fans wall controllers that work pretty well - but their current-gen wall controls are hardwired bluetooth remotes, which is subpar for something that's connected via wire. (And they cost $210/each, which is pretty egregious for a wall switch.)
What?
Every house I've ever lived in over my many decades of life has had ceiling fans. I've never known one to fail, never known one to be noisy, and never known one to have inadequate power. I've personally installed a couple and know those got wired straight into AC mains power... so unless they have a converter built in, I figure that every ceiling fan I've ever lived with has been AC powered.
Unless you've been working with absolute bottom of the barrel fans (and those fans are worse than I could possibly imagine), this smells like industry propaganda to me.
> There's no clean mechanism to control a fan's speed in-band on a normal AC wall switch.
OP is asking for a normal pull chain or switch... one that's attached to the fan housing, not some doodad that's embedded in the wall and needs to be specially wired into the fan electrics. I've been to the houses of a few friends that have had fans controlled with a handheld wireless controller, and I can confirm that that was -overall- way worse than hauling my ass up to pull a damn chain.
I’ve looked at a product called Bond that seems to facilitate it. But haven’t yet tried it.
It might be that POE power supplies get hot - I've noticed the POE hats for the raspberry pi need a fan
I tried changing channels in the remote but that didn't seem to help much. With the second neighbor, the fans were in my living room and their bedroom. We agreed to control fans in shifts (I turned mine off at night).
It's hard to believe it's just a very unlikely coincidence. Maybe the channels are too few or narrow to be useful? How hard would it be to implement some psuedo-UID?
Are you mad? That would cost low-single-digit pennies per unit!!! </pennypinching_bigco_derision>
Things drawing an average of a few hundred microamps while the fan is running. Probably because it's blasting a keep alive packet once a second or so. It does that because a transceiver costs an extra 50 cents.
That is abnormal compared to my experience. I have a lot of bulbs in my house between recessed lights, fixtures and lamps, probably 150-200 in total, and in the 5 years I've been in this house I've had, I think, 3 bulbs in total fail.
I wish it caught on to have LED lights powered by a barrel jack DC plug like you have for most electronics. It would be a huge win for longevity. Sure it's not backwards compatible with fixtures designed for light bulbs, but the cases we're discussing here are complete light fixture replacements anyways... The fixture could have a barrel plug that you connect to an inexpensive commodity DC power brick which you then hide away in the ceiling.
I bought some high CRI LED bulbs from some place recommended in an HN post.
It also prevents the user from changing the bulb if they want a different color temperature or better CRI. Most of the built-in lights I see are in the 3000-3500K range, which is cooler the warm white I’ve chosen for the house. If I could swap the bulb it would be an easy fix, but if it’s built in then I’m stuck with it.
A high CRI single color temperature bulb beats them in light quality.
Most people aren’t going to notice, but if you’ve done any work with color, lighting, or photography then the average consumer LED lights feel terrible. They’re mostly blue light with a little bit of other colors to make them appear white to the eye.
"LED bulbs" die because they have to rectify 110VAC (hot) into LEDs (hot) into an enclosure that was designed for incandescents.
In a proper enclosure, with cooling (it's a fan), they will actually live their fully-stated lifetime - assuming the fan's upstream power supply makes it.
A recessed can or “upside down” ceiling fan globe with an open bottom is technically an enclosed fixture since heat rises.
Typically fans with built-in LED downlights are engineered to actually dissipate heat - and they have a much larger area to do it in. Edison-format bulbs are inherently space-constrained.
But in an "old school" hardware, you'd then replace the bulb and get a new "lifetime" out of it, here you have to throw everything away.
An AC motor has basically nothing inside that can fail (maybe the capactitor, but that can be replaced), and can work for a hundred years and more if properly maintained (mostly cleaned).
On average ~6 hours per day (living room with night owls living there), is ~2000 hours per year... 5 years at 10.000hours expected lifetime for the leds, 10 if the stated lifetime is 20k hours... that's not really that long.
Lightbulbs came in sockets because they were meant to fail. First by accident, later intentionally. They were also quite breakable because they were made of glass. LED lights don't have these problems unless they're designed to. Which is the meta-problem - how do you know which ones are planned obsolete?
Forcing an LED system into a lightbulb from factor has quality and cost implications though. A good LED light has a separate power brick inside the enclosure. Which is what you see in these fan lights.
I would hope that at least some of this would get standardized over time
Let me know how the non-replaceable sealed bearing packs in these AC or DC fans fare after 10,000 hours.
In a proper/high-end DC fan, the bearings are failing before any motors or LEDs.
Regardless, in a Big Ass Fans Haiku, the downlight is a completely separate/replaceable module - and it isn't going to fail before the bearings or motor.
Edison screw LED bulbs are the inferior design by every objective measure.
...your AC-powered ceiling fans are failing (or even "just" substantially degrading) after a little under fourteen months? What garbage are you buying?
I’m under the impression at this point that they just do not do well inside can lights. I honestly don’t think the average lifespan is much higher than incandescent in that scenario.
This 120v-using USian has had many fail, and if they don't fail by intermittently blinking and flickering [0], they fail by slowly giving me worse and worse and worse headaches [1]. Unless you choose to count the fact that they were technically still emitting light, I've never gotten the rated lifetime out of a screw-in LED bulb.
[0] ...as all of the ACE Hardware ones did...
[1] ...as all of the dimmable [2] CREE ones did...
[2] These were never attached to a dimmer. At the time, the advice was to get LED bulbs rated for use in a dimmer, as it was believed that that would get you higher-quality construction.
Me - I have the exact same bulbs in my off grid property, and in my on-grid property. On grid, it's about 18 months MTBF. Off grid - it's been seven years and I haven't had to replace a single bulb yet. On-grid our power is anywhere between 205 and 235v, often has spikes up to 260+, and has like 99% uptime. Off grid, it's 230v, day in, day out. Grid power is terrible in most places.
I have this issue as well, of burning thru LED lights.
