Nichia 219C, testing a 5000K 83CRI emitter, comparing with a XP-G2 S4 2B and other leds

[Hikelite]

Do you know what voltage bin is this, M1 L1 or L2?That would be nice to know since not all 219C will be identical in forward voltage.

You can see in the datasheets that 219B-V1 for example is rated at lower vfs than the 219B, and basically identical to the 219C's vf ratings.

Wow! I really hope the high CRI variants show such a big performance bump. The low Vf and similar output could make this a serious candidate to replace the XP-G2 in throwers like the 1504. How long till you dedome one yourself?

[sesgum]

Wow thanks for the informative review. This new nichia is very promising.
And I feel totally out not know how high the output can be for these smaller LEDs (xpg2 and nichia). :8)

This is all what is on the Lumintronics site about the led, it suggests an L2 rank.

Thansk Djozz.... again interesting post! and very helpful and informative!

thanks for the hard work!

[ryansoh3]

Great results, thanks for the testing!

Amazing how much this LED can take without blowing. Are you listening Cree?

[bibihang]

Thank you djozz!

[finges]

thanks for the review!

[Halo]

1+ Thank you Djozz!

[ReManG]

Great review, eagerly awaiting this LED… Thanks!

[AlexGT]

Thank you for all the detailed information you put into the review

[MustSimon]

Thank you Djozz! How is the tint and color rendition?

[viperbart]

Does that graph mean it wouldn’t play well with a FET driver?
Back to the piggybacked 7135 drivers if we want to max the LED?
… or of course an LD-1 / LD-2 from LED4POWER.

Edit: Seems like 4.2volt from a fresh IMR18650 would be way too much power…?

[Firelight2]

Wow! This sounds like a great LED. Can’t wait till the high CRI versions come out.

Sounds like all my 219s will need to be upgraded sometime this year.

Great job on the review Djozz.

[led4power]

Great work,djozz,as always.

When you take nichia's 80+CRI into consideration,nichia looks even better.

One question:could you please take a picture of XP-G2 S4 die?

I posted few pictures of "unusual" xp-p2 with definitely bigger die size (~2.3-2.4mm² ) in this thread:

CREE silently increased XP-G2 die size?

Bought some xp-g2 leds from fasttech in January,put some of them on noctigons and in gasoline,but immediately I spotted one "intruder" with unusually high die size,visible by naked eye(also you can see crappy xp-g2s with out of center die,all purchased on the same order form FT,factory rejects?): [image][image] [image] [image] After gasoline dedoming: [image] [image] [image] [image] I don't have good enough camera or skills for close-up shots ,but die isn't just bigger, vias (dark dots)…

[kyfishguy]

Oh boy oh boy oh boy. I sense a new triple S2 in the not so distant future! Thanks for all your testing djozz.

[Kloepper_Knife_Works]

Great info! Pilotdog68 is right, these could be real winners in a 1504. With the larger die I’m not sure there’s much of a throw advantage, but more lumens, similar throw, and longer time in regulation. What’s not to like?

[THE_dAY]

Wow thank you Djozz for such thorough testing and comparison!

I am interested in your thoughts on the tint/color rendering of this 5000K/83CRI version.

Thanks!

I didn’t realize the die is larger.

Also, someone above had a good point. The Vf is almost too low. You would have to use a linear driver with this one, no FETs. And it still isn’t as efficient as an XP-G2.
