Cree XP-G 3000k 90+ CRI vs Nichia 219 4500k 92 CRI: which one do you prefer and why?

[mvyrmnd]

I may have to buy a 219 based L334 to retrofit into my Tri-EDC....

[mvyrmnd]

That cool white XT-E has by far the worst color shift over viewing angle. Look at the yellow fringe on its hotspot, none of the other emitters show anything that bad. It confirms what I just read about a hour ago about someone's Mag mod using XT-E's.

The XT-E Warm isn't much better....

[wquiles]

Excellent work as usual Serge.

Thank You.

Outstanding work Serge

just returned from the trees (it's 3:00 AM here). 11 makeups were captured (all triples, CARCLO 10507 lens, all driven with 1.5 amp).

DOWNLOAD THE PICTURE (1200 x 1072, it's TOO large to post it here)

Very interesting! What do you think when you are looking at pictures with XP-E 4D0, XP-G 4D0 and Nichia HiCRI?

[Lux-RC]

I double-checked the bins, according to the box stickers both XP-E and XP-G are 4D0.
I may presume that XP-E's spectrum shift is caused by the overdrive. 1.5 amps is far beyond its official limits.

[qwertyydude]

Wow the XT-E really does have a color shift across the beam. Makes my XM-L look downright normal.

And the 219 does look great with its neutral white. My 90 CRI warm XP-G just looks a bit too warm. Warmer even than my xenon incan module.

Thank you very much for your excellent work - I think these fotos will help a lot of people make their decision. There are lot of nice LEDs to chose from XP-G and Nichia 219 - but the samsung is good too.

[Glenn7]

Do those Samsung 3535 Led's come in 5700 or 6000k?? because they look like a good balance between flood and throw (XP-E & XP-G)

[Glenn7]

Well I'm proud to say I killed another thread..... :0(

[Lux-RC]

nope, Samsung offers only neutral and warm color 3535's.

Correct, they're not just more bright than CREE's R4 but due to smaller die size provide more throw.

I have a Samsung 3535 and its truly a cooler tint, 6000~6250+K easy.
Also, the circular emitter itself, looks minutely larger (like .2mm) than the xp-g by eye,,,,its soo fractionally close though.

The beam characteristic is like a hybrid between an xp-g & xp-e,
there is no doughnut aspect when testing a couple different reflectors.

The Samsung 3535 is a pleasant surprise to say the least..

edit to add pic:
I took efforts to get the emitters on the same line, because the 3535 light has a deeper reflector
(same tint filters on both)

Thank you for the replies It was a help.

Hi I am just new in this thread. In my case, I would prefer the 219 because of it's high CRI, more lumens, and neutral tint. But I guess we all have different opinion on this.

[Lux-RC]

I rely on the official whitepaper from samsung -> http://samsungled.com/eng/product/prdHighPower.asp

6000K is not listed there. They same was provided my a local representative.

[orbital]

Really hope your not implying I don't know my tints or temperatures.

I compared my Samsung to my WC tint R3 xp-e ,,, the Samsung was slightly bluer.
{WC is well over 6000K}

See post #1074 http://www.candlepowerforums.com/vb/...t-3%29/page36&
The reason I said Anyone spare a light amber filter? is because it was very cool cool tint.
Beamshot is of the Samsung, of course.

Trust me, I wish it was more neutral out of the box, then it could have saved me putting a filter on it.

[Glenn7]

Hmmm something is strange here maybe you got a rogue Samsung because if you look in lux-rc's beam shots there is no comparison to the xpe in color 3535 is definitely warmer http://www.quazzle.com/temp/beamshots-may-2012.jpg but throw is the same.

[psychbeat]

Wow- I just received a Malkoff m61-219 this AM and am digging the tint for sure.

Reminds of a 4A XML a bit but better.

The outer ring in the beam is only noticeable from about a foot away.

I do prefer this over the 90cri XPG although ideally the 219 could be a hair warmer.

Nichia is KILLING IT !!!
Cree & Phlatlight are going to have to step it up CRI-wise.

[clg0159]

Well, I would prefer a tint in between the two actually. If I had to choose though it would be the 3000K XP-G. It just looks better to me outdoors which is where my lights see the most use.

Yah I was thinking the same thing though I haven't used the 219 outside
much yet & my hiCRI xpg light is with a friend ATM.
The 219s tint is actually between a 4A & 4C XML - those are the closest I have seen to it.

My bike headlamp will soon have a triple 219 w narrow optic & 2 bare
XPG hiCRI for flood which should be the best of both!!

[djozz]

I modded a cheap dx 16340 light with the 219 (it runs at 700 mA), and went camping with it this weekend, and I must say: this is the most pleasant outdoor light I have ever seen. Actually, it's a whole new experience; i was ether used to the old incans, rather yellow but I never knew better, or i used the cool white led lights that kills every colour in nature. This light shows up the greens, reds and browns so vividly as I have never seen from an artificial (outdoor) light before, and still does justice to the blue colours.

Even compared to my quark mini high CRI (xpg 85+CRI, 3000k) I prefer the 219 Nichia by far!

[arek98]

IMO, unless someone particularity likes yellow tint, high CRI needs to be in 5000K-5500K range to make sense. This is about daylight CCT.

When calculating CRI result is compared to 100 CRI perfect light sources but the problem is that CCT is adjusted to CCT of light being tested. I.e., if we assume that our perfect light is 100 CRI and 5500K and tested one is 3000K then comparison is between how colors are rendered by tested 3000K light and color rendering by our perfect source AFTER ADJUSTMENT to 3000K.

This is known shortcoming of CRI and this is why newer methods are in development. One of them is CQS (Color Quality Scale).

[Shadowww]

I prefer 4500K Nichia, it's way closer to sun's 5000-6500K range than 3000K XP-G (which looks like horrible ill-red incan bulbs).

[bshanahan14rulz]

I like the nichia. 4500k is as warm as I need. I wouldn't mind warmer, but only for the warm fuzzy feel-good feeling of warm light :-P

I will say that I haven't tried any of Cree's 90+CRI LEDs yet, although I still do like my Cree XR Q3 5c.

[LEDAdd1ct]

The XR-E Q3 5C is a sweet LED, and one of my very favorites!

Yah I got my GF a cheap Fireworm floody headlamp that has one.

Super nice!

Still prefer the 219 I think but I do like the Warner tints for comfort

[moozooh]

Great comparison shots, they really made me appreciate the 219's marvelous peachy neutral tint. Thanks a lot! Any chance of similar shots done with Luxeon Rebels?

[Pöbel]

Absolutely awesome fotos. Many thanks for making these.

The fotos show exactly what i feel. I had a HighCRI XP-G in my EDC. It was nice, but just too yellow. I moved to a neutral instead. Now comes the Nichia. Yes, could be brighter - but the colors, the tint, this is just such a beautiful LED. I absolutely love it outdoors, the greens, the browns, the reds, grey is grey and my hand looks like a real human hand, not the hand of Hulk. AWESOME!

[phips]

Yes, super great comparison Lux-RC!
Now I really need a light with a Nichia Led (perhabs Zebralight might offer a nice headlamp in the future?).
Concerning your measurements: do you think the Nichia could perform better when driven within its specifications?
(Nichia rates it up to 1.5A constant and 2A pulsed.)

[jorn]

I like the nichia, then the rebel, then the xp-g. Tint is better and "cleaner".

[RichLee]

They are all regulated, just some better than others? Would be my guess.

Impressive collection you have there! Nice beam shots too.
