Channel 7.

I still don't see why anyone would buy them though, because dollar for
dollar, halogens win hands down.

** The claim made was for * 5 times * the efficiency of a halogen lamp
with similar light output.

Also claimed was a break even period of 1 year and a ten year life.

Plenty of reason to use them, if true.

YOU DUMBFUCK, HEE HAWING ASS.

I still don't see why anyone would buy them though, because dollar for
dollar, halogens win hands down. Only perhaps tree huggers may buy them.

The latest SC mag has an article on Ostar LED lights that are claimed
to be on par with halogens for light output:
http://www.reuk.co.uk/Osram-Ostar-Lighting-LED.htm

I don't have the article in front of me, but IIRC several thousand of
these were installed in some European supermarket complex.

That's about what I would expect. However, LEDs cost a LOT more than
halogens, so even allowing for reduced life in halogens compared to LEDs,
halogens still win.

LEDS have their place however, especially where the long life makes up for
their initial high cost. Such as high ceilings, or difficult to access light
fixtures.

What I'm objecting to, is the blanket comments that paint LEDs to be the
end-all-be-all in lighting technology, to the determent of everything else.

Much like the CFL debate. Sure they have their place, but not as a simple
drop-in replacement.

Any time you need more money for your medication Phil, we'd all be
happy to help you out, just post your PayPal address.

What a pathetic pile of sub human excrement is DL Jones.

The lying, gutless autistic cretin has not got one single clue about any
damn thing.

Just constantly spews his brainless bullshit about for the sake of having
something to say.

Peeeeeeukkkkkkkkeeeee

I haven't seen that SC yet, but looking at the specs for that Osram unit one
thing stands out - the CRI (Colour Rendering Index) quoted is 80, which
makes for pretty horrible light compared to the better fluorescents.

Sounds like a cock and bull story.

The mind boggles at how that one would work.

Someone else at sci.electronics.repair also commented that his
personal experience of LED colour rendering was less than
satisfactory. However, the inventor who is the subject of this thread
claims that his LED lights don't have this problem.

[Mr.T]

No, of course not. And I don't see the reason you ask this question unless
you missed the bit in this thread that places them in series - enough to give
a suitable average current, along with suitable limits for waveform peaks and
local power grid variations.

So what happens if one of the string fails?

You'd *give* money to Phil???
Cheaper to just ignore him.

But unfortunately provides no evidence for any of his claims so far.

** Depends on the type of failure.

IME - LEDs commonly fail to a low Z or short cct.

Open cct or high Z failures could be mitigated by a zener in parallel with
each LED.

[Mr.T]

** Depends on the type of failure.

IME - LEDs commonly fail to a low Z or short cct.

Which may eventually lead to a cascading failure without separate current
limiting.

Open cct or high Z failures could be mitigated by a zener in parallel with
each LED.

Possibly, or they may not bother. We shall have to wait and see if it's
another case of Xmas lights

** I've already made my point, which was that the Osram Ostar LED units that
were mentioned have notably poor colour rendering. I don't believe this is
incorrect, nor that difficult to comprehend, however if you are having
problems, I'm happy to explain anything you don't understand.

I'm sure his "team of Chinese scientists" have it all figured out... :-

** A CRI of 80 is actually rather good - better by far than most fluoro
lighting.

** It is totally wrong.

You only need to explain what blog you found that idea on and put it back.
