A friend of mine has always been into LEDs. He was their big fan even in times when only red, green and yellow ones were readily available.
Two years ago he moved into their new house and they've already about 500 LEDs there! He's removed all existing lights (the house isn't new) and put LEDs everywhere. He's also a kind of "geek" - recently he's made a sleeping LED light for their daughter dimmed programmatically by an Arduino module with a "breathing LED" controller, of course.

He's a nice and smart person anyways. So why he's so misLED? He can't accept anything but LEDs even if he needs to get massive copper heat sinks to keep them cooler - in places where a couple of fluorescents would do much better.
He also periodically orders innovated types of LEDs from China and grumbles at different CCT of LEDs that should be the same (e.g. 5000K) but they're not. Not seldom he receives a broken package (LEDs smashed by a heat sink in the same package etc.) but he continues in ordering them. So I think he's a really misLED person.

misLED? Those, who promise to their customers unrealistic expetctations and hide aspects, that need attention (and my look as weak point)
I have witnessed a discussion about LED stripes, where the seller recommend some strange "brand" instead of I guess Philips (I'm not sure about the exact brand, but that does not matter). The argument he have used (pretend it was Philips):
"These are better than Philips. See, Philips requires to mount them only into that special profile, but these could be sticked just onto anything".
Well, to a question, why each piece of the demonstration showcase (different sections of the same stripe) was so different in brightness, when according to the life claims all should be in less than 20% of their rated life even when burned 24/7 since they were introduce3d there, he (no wonder) could not answer...

Well, according to me, even the Cheepeese were not that bad, given the abuse they have received there, they had already about 15khours while quite overheated all the time (the shop is open daily 8:00..22:00 and at least all that time they are ON and they were there like that about three years). With proper cooling they could have well meet the 30khour rating. But the problem was, the advertisement had promised 50khour life and the possibility to be glued onto everything...


Street lights:
With LED you have technically way better possibility than with practically any other source to design the optics so, you maintain the required illumination with less glare and with way lower raw lumen requirements (and hence the possibility for a significant energy savings, although the LED efficacy alone is not that high). But that remains just the possibility, until all involved really do not do their job well.
And with "all of them" I did not mean only the fixture design engineers and makers, but also the ones specifying them for given project and those who finally install them in the field. The thing is, when you have accurate optics to do the task, it becomes very sensitive to e.g. the aiming of the fixture (with LPS you may turn it nearly 90deg and still the performance of the lantern would be n early the same; with the accurate LED systems the aiming error of 10degrees means the fixture does just glare and not light).
And the correct specification, together with the correct installation are the two major problems I have seen with bad working LED installations intended as an energy saving attempt (both of them are represented on many posts here on LG). But the inadequate fixture design itself is not that rare problem either...

Sounds like they are big on technology related fads.  Thus the whole hog push for LEDs as they are 'in' at the moment and have not been around long enough to have problems like their permanently built in nature requiring total fixture replacement when they die bite users in the nubblies (although there are stories coming out about premature failure, but those have yet to make much of an impact).

Do these misLED people go as far as refusing to use a computer power bar that has a lighted switch containing a neon lamp ?

They probably couldn't tell the difference between an LED and a neon lamp. 

... like their permanently built in nature requiring total fixture replacement when they die bite users in the nubblies...

In that respect the LED's are exactly the same as any other electronic: Normally it does not wear so fast, it would need replacement before the complete fixture.
But that does not mean it does not fail, because of the quality, but then a switch would fail in the same way as the LED or their ballast. Or something in the mechanical construction cracks. In all that cases you need the thing to be disassembled and the faulty thing replaced by some expert, the LED itself is no difference.
Moreover most frequently are the ballast failing and not the LED itself.
Agree, it is matter of build quality, but with "classics" that would be the same, if someone want to squeeze the cost in the same way.

LED lights can be good-but they have to be properly represented.I have a catalog that has some lighting equipment and they do misrepresent their LED lights.An 80W LED "Corncob" bulb will NOT replace a 250 or 400W MH or HPS fixture as the catalog suggests.And for what you get for LESS light output you have to pay MORE for that LED corncob bulb as opposed to a MH or sodium bulb.OK-to get the same light output as the MH or HPS lights you have to use MORE of those LED lights-more wattage-then you use MORE power!The American Electric LED lights installed here at our transmitter site DO put out more light than the older mercury ones.-and they draw 215W as opposed to 250 or 400W.But I do like the quality of the mercury light.The LED lights we now use put out a warm color--much like metal halide.The only large LED lights I have seen so far I could like.Feel the HID sources wether fixed or portable still put out the most light for the lowest purchase cost and power used.

The thing is, when you have accurate optics to do the task, it becomes very sensitive to e.g. the aiming of the fixture (with LPS you may turn it nearly 90deg and still the performance of the lantern would be n early the same; with the accurate LED systems the aiming error of 10degrees means the fixture does just glare and not light).

Yes, that's an important observation.

I have spotted another specific issue: They set up the system to light the lane but do not consider the sidewalks. No problem with HID gear at all. But with the most recent LED stuff this approach can very easily leave the sidewalks in the dark.

Governments.

@kai: Good observation about unlit sidewalks!
But please don't change the original topic "Subject". This is not about LED street lighting (only). When Luminaire used "Reply with quote" option, the topic was listed under your changed subject. Thanks. I'm changing it back to the original subject...

I didn't know changing the reply subject influenced the subject for the whole thread.

On the site main page there was:

by Luminaire

since Kai changed the subject and Luminaire chose "Reply with quote" (+ deleted quoted Kai's post).
I thought it's a new topic but it was just my old topic under a different subject.
(When you browsed into General Discussion category, there it was under its original subject.)

Not a big problem but better to keep things organised.

@merc: I agree that he is going overboard; the only place I'd use less are areas where the fixtures are hard to reach. Oh well, more incandescents to go around for us.😏

2-3 years ago my brother bought some LED lamps for E14 or E27 from Dealextreme. He later said one of them got so hot that one LED desoldered itself.

My best friend is totally against LED lighting.So am I  Nor he or I is misLED
