Don't get me wrong - I'm just about to order one of those clickies (for several reasons) ;)
What I, as a relative newbie, don't understand is the hype about the burst mode and runtime of 1 hour at 100 lumens.
If for example I look at http://www.cpfreviews.com/NiteCore-DI-Extreme.php it runs for 47 minutes at 170 lumens. Can that be considered as a "self-destruction-mode"?
Or, even more strange: my even smaller Fenix PD20 is supposed to deliver 180 lumens for something between 30 mins an 1 hour in "Turbo Mode". Am I destroying my LED if I use this mode for more than 10 seconds?

Peter, a bit confused.

Powering an LED as hard as possible to get every last lumen will shorten the life of the LED, period. Compare it to driving your car with the "pedal to the metal".

Who is "Peter"? :thinking:

No, the Clicky has very advanced thermal management which prevents you from damaging the light. This is one of the things that makes the Ra lights so reliable. No LED frying.

From what we've been told a slightly speculative guess is that the 10 sec is there to protect the user against himself and to prevent bad runtime results. Some like this line of thinking, some don't. It may prove useful in practical use though, we'll see.

Oh paxxus, so I should say "Karl", what do I do now---or are YOU just too clever for me and know the guessing game??

Hey Guys,

calm down, please.
If this was meant to introduce myself somewhere in this forum I'll do so :cool:

Not to worry PeterK, it's clear to me paxxus is not familiar with Peter Gransee who had, at one time, affiliation with Henry Schneiker in the development of the Arc4+ when Gransee operated the original Arc company. The use of your name in reference to yourself was unusual...confusing... We're cool! Not to worry :cool:

Peter,
Four post CPF member.....Welcome to CPF and to the thread that was intended to share the beauty of the best little light east of the Rockies. There is a weird mystique about your appearance here, but to me you are just another Clicky loving guy. Keep on truckin'.

Jeff

In Henry's last post he made it clear that it (burst) was not a durability issue, but rather a run-time issue. The other lights you mention are pushing the LEDs almost as hard as the power supply's will allow. Nothing wrong with that. OTOH, what we buy when we buy an HDS light is a not a light that eeks out the very last lumen of an emitter, but a light that can survive extreme conditions and still work when you need it to. The 1 hour figure was chosen as a reasonable amount of run-time. These lights are regulated to perform to at least these specs.

I'm not saying that you are destroying any light by operating it at it's advertised specs. Most lights will generate a considerable amount of heat when run for extended time, however.

The key word here is "supposed". First of all, Fenix states their lumen claims in theoretical emitter lumens. Second, most flashlight makers state and measure their runtimes to the point where the output drops to 50% of maximum.

What we're talking about here, on the other hand, is true, calibrated and measured "torch" lumens and FLAT output at maximum level for an hour.

Just to give you an inkling of how misleading lumen claims can be, P1D Q5's claimed 180 lumens are actually more like <130 lumens. A P3D Q5 is supposed to be giving out 215 lumens in "Turbo mode". An Arc6, with it's 170-ish lumen levels 6 and 7 visibly beats it in brightness.

Well put. To further prove your point, I will quote Henry's well deserved partial slap on my hand for spreading vicious rumors about emitter aging through excess heat....."Our exceptional thermal path, thermal limiting and constant power drive take care of those issues very nicely. Utility is the primary parameter." Henry has become modest in his young years! :crackup: For the full slap on the hand, and other vital information, go here.....

The Clicky is the only flashlight I am looking forward to and I have been holding off buying any other flashlights for 2+ months now. Website says it will be available in October, 6 days to go - I'll keep my fingers crossed. I wish I had preordered one Cn-140 :ohgeez:. I'll probably sell my Tr-85 to fund the Clicky (tough decision).

Ok-

I've just finished reading 40 pages of posts over the three seperate threads concerning the RA Clicky. I have *I believe* read all the links from Henry concerning the new light - the diagrams, the instructions, etc - and I have yet to find - through all that reading - the answer to the question that I have been wondering about since I started reading...

What LEDs are being used in these lights???

I found this seemingly pure speculation:

...Wide likely uses a SSC based LED, while the Narrow is likely to use OSRAM...

but nothing definite. Why not??:thinking:

Of couse, maybe with all the mind-swirling posts that have been plastered here, I may have missed it, but I'm sure I didn't.

Does anyone have a definite 100% sure answer? Henry...?

if he uses the same brands as where in the twisty, than SSC and OSRAM it is.... no one will know till we get our hands on them

I'm off to watch saw5 but i will leave with this statement.It is my belief that when the new clicky is out it will be THE light to have and the light that will get the job done period.And when all is said and done even those that are having a hard time with all the changes and delays will soon get one for themselves and say you know what Henry was right IMO.
