WHY.?? « on: October 07, 2021, 07:57:44 PM » Author: Mandolin Girl
This has been happening more and more recently. ???

Members have been posting pictures of dead lamps, and I don't know why they feel the need to do so.  :wndr:

Now I could understand if it was a rare lamp in a clear envelope where you could see the failure, but a generic modern L*D just baffles me.  :poof:  :(

Because they can? I think as long as it isn't repetitive, it should be fine.

Clear lamps that are not LED have failures that are almost always the same. LED lamps can have failures that are different since they can have varying ballasts and components, as well as individual diodes or COBs that can cause the lamp/light to fail.

So really, what I'm saying is, even the most boring LED lamp/light can have a different failure mode, just like fluorescent lamps and their ballasts (mainly the electronic ones). It's always interesting to see what may have caused the failure if someone could reverse engineer why it failed.

In the case of that Philips lamp, Andrew (Globe Collector), is spot on, it will be an individual diode, all mine were and none of them even reached 6000 hours!

That's as may be, but how does a photo of the circuit board help with that..? If the blown component is obviously blown, such as if it is blackened, then the reason for failure is already known. If it isn't, how does a photo of the board help..?

For something rare and interesting, maybe it would be worth pursuing, but for a cheap generic LED, is it worth it..?

Just my thoughts.

With failures in devices with a decent amount of electronics with a lot of components, sure a blown component is a blown component, and as you said, could be the cause of the failure. But a photo of the board would help a lot in determining a failure. Sometimes that component failure was caused by another one, or maybe the source itself.

If you say something failed people can help you determine the cause. For example, you have a Sylvania LED lamp, and you say the failure isn't visible, say it's a Sylvania LED lamp, but provide no picture of the board or driver, how can people help you? A picture of the board or driver can get an expert to tell you what to do, what could be wrong, and what to fix right away. But the expert will never know what your problem is if you just state that your Sylvania LED lamp is dead and you didn't post pictures of it. That's why you post pictures, for others to help you, and with the knowledge the experts give you, can also help others if they come across a topic about it.

Sure, older and rarer stuff could be worth repairing, but sometimes there's that someone who wants to repair everything they have or at least know how to repairs that thing. Or is genuinely curious and clueless about the failure mode of the thing despite not being tech-savvy.

Okay, so in that case post a topic on the forum asking for help and attach the image in a file.  :wndr:

To my mind, if something cheap and trashy fails, is it worth even trying to determine the cause..? Maybe, if you have the right type of mind, but I have more than enough other equipment that I would want to know how to fix, rather than a cheapo lamp that to me is hardly worth the time and effort.

At the end of the day, what is this site for..? To me, it is discussing and exhibiting interesting and unusual or rare lamps, not cheap generic LED's that are easily replaceable.  But each to their own, I suppose  :-\

I have no issue with people posting dead lighting stuff.

Other members have expressed concerns though, the forum is the place to ask technical questions, not the gallery.

Who? Also as far as I'm concerned both are for questions.

Who is not the question here, the fact that they have is enough for me.

I've always believed that there is a divide between the gallery and the forum, why else are there all the different boards.?

Well I've always observed them being used interchangeably. And I don't think a handful of members who do not want to be named should dictate what the vast majority partake in.

If someone wants to post a text based question. Share data, or post something for sale let them.

If someone wants to post a picture based question, share data or burnt out light bulbs let them.

They aren't hurting anything. Making people tip toe around arbitrary rules to appease the minority are what kills forums and makes mass social media site more appealing.
