Peak Eiger, now with Nichia 119-H1 High CRI

[ElectronGuru]

Thanks Guys. These were brought in to test for a variety of possible uses (including Triples). Most were a flop. Huge credit to Curt for making these possible!

I hand fired each head before shipping and did not see temperature variations. They were delivered to me as 4500K but I have not taken the time to meter one with the camera. Its possible these are warmer than reported.

... The HDS is supposed to have a color temp between 3700k and 4000k and the nichia is supposed to be 4500k, but the nichia appears significantly warmer. Do I have the specs mixed up in my head?

Same here. My High CRI Eiger has a warmer tint than other lights with around 4000K color temperature (HDS High CRI, Malkof M61W, DQG II neutral). It's comparable to the tint of my Quark Mini Warm White - more like 3500K I guess.

The Nichia LED seems to be considerably less efficient than a Cree XP-G LED. I did a runtime comparison test with the High CRI Eiger and an older Eiger #6 with a XP-G R5, both using freshly charged eneloop's:

High CRI Eiger (Nichia 119-H1):

0:00 - 34 lm
0:15 - 29 lm
0:30 - 27 lm
0:45 - 13 lm
1:00 - 4 lm
1:15 - 2 lm
1:30 - 1 lm

Eiger #6 (Cree XP-G R5):

0:00 - 41 lm
0:15 - 41 lm
0:30 - 41 lm
0:45 - 41 lm
1:00 - 41 lm
1:15 - 41 lm
1:30 - 17 lm
1:45 - 5 lm
2:00 - 2 lm
2:15 - 1 lm

The measurements were taken with a standard Eiger body (no QTC).

Nonetheless, the High CRI Eiger with the QTC switch is a very nice light. It feels incredibly rugged (mine has a SS body), is bright enough for my needs and has a beautiful color rendition.

Got mine today. Great light!

I will say that they are not as cool as I had hoped but the beam is great. The temperature is definitely not as warm as the Cree XPG High CRI in an Eiger. I really like the narrow now too. My Cree is wide.

I really like the narrow now too.

So this is the "narrow" optic? It looks pretty floody to me.

When the Eiger Rebel was introduced, Peak rated the Eiger wide (reflector) field of view to be 30 degrees, the Eiger Medium (optic), 15 degrees. I forget the FOV of the Eiger Narrow (reflector); probably 8 degrees. These values remained more or less the same when the Eiger switched emitters to the Cree XR-G. But I don't even know whether the Eiger uses a reflector, an optic, or nothing but flat glass with the Nichia. I've read that the Nichia has its own optic built-in.

Compared to the Eiger XPG wide, the Nichia narrow is narrow. Wide is really wide (and very useful).

I believe these values are still in effect. However, larger LEDs cannot be as well focused, so angels are exaggerated. Eiger/narrows come with a clear/narrow optic (mounted under a window). They are closer in size to one of the 3 lenses found on the Triple XPG. A smaller (less powerful) LED would be needed to achieve true throw.

Nichia CRI's were installed with the same optic.

I've only had my high CRI Eiger for a few days, but I am very pleased. The warm tint is beautiful. It looks like an incandescent to my eyes. I picked up the long keychain body and a 10180 body as well. I am not particularly fond of the extra length of the long keychain body over the lugged shorter version, but it's nice to be able to screw the keychain part off when I want it to tailstand.

Am I the only one who finds the momentary switch to work poorly? I get much better results twisting the head. You have to put a ton of pressure on the momentary switch to get it to work.

I should have tested both setups before shipping. But I have developed unusually strong hands doing all this assembly. Its possible it felt natural to me. Please shoot us an EM and we'll see about shipping a softer setup.

I just tried to use the switch I already had. I didn't purchase a new one. And anyway I intended to use out as a twisty. I just tried the momentary for the heck of it. Thanks for the offer, though!

I have a number of the QTC based lights with the momentary switch and they generally are pretty hard to operate. You need strong hands. If you just need a blast of light, it is fine, but for extended operation or a specific amount of light you need to twist.

I really like using the momentaries without the QTC... basically as an on/off switch. Nice to have the option.

The QTC sandwich requires more depth which much be accounted for by the switch.

Pre QTC momentaries have a pin and spring at the tip. Pull this out/off and reinstall.

I received mine today. It is warmer than I expected but so far I like the beam alot!

Why we don't see more lights with this emitter?
Is it significantly less efficient than other emitters, or is it hard to work with for some reason?

Its hard to get and if the engineering works out (few would design a light specifically for it), a sales risk.

Hmm, if I were to attempt to redo the lighting in my house, this emitter (or something like it) would be ideal for the kitchen, bathrooms, and dining room.

Is it hard to get because it's already being used for other applications or is it that Nichia simply doesn't like selling in small amounts?

Nichia only sells full reels of 1000 LEDs and you cannot order a particular
color tint bin or power level. They are not interested in selling anything
but OEM quantities. We have tried several times to get a particular LED
and have been told that what they send is whatever they feel like sending.
We just gave up on them, period.

That would mean that we would have to play the tint lotto. I'm not doing that so good on you for NOT going with them IMHO.

Can anyone tell me why my Eiger heads are different sizes? The one that was modded with the Nichia 119 is slightly longer. The other one is from a long/key SS QTC Eiger. What's the difference?

That is to get more travel to accommodate different AAA battery lengths.
