Nichia 219C D260 9050 90+ CRI Emitter output test by Texas_Ace

I have some 3000k as well but can’t decide what to put them in, kind of running out of hosts lol. I think I am going to try one in a P60 host tomorrow.

I didn’t get the 3500k as I was too late to put my name on that list and they sold out. Although generally 4000k is about as warm as I like anyways, 4500k I consider ideal in may cases. Although these nichia 4000k appear closer to 4500k Cree’s.

I built the luminous tool I mentioned earlier with the 4k 90+ CRI LED. At the same time I built a hugsby xp-1 with a 219C D320 5000k 70CRI from MTN.

Comparing them side by side tonight and the differnce is amazing. The 70cri LED looks great until you see it next to the 90cri, it completely blows it out of the water.

I get ~500 lumens from the 70cri and ~450 lumens from the 90cri.

Both are great lights though and handle a 10440 surprisingly well.

Yeah interesting how perception is on tints.
When I got my first HCRI it was an old Nichia 119T and it was better than anything I’d seen, every color ‘popped’ with it.

But if I saw that same Nichia now I would not be impressed in the slightest. It would look like a green Cree next to these newer gen Nichias.

Btw, clemence might get some 219B R9080, either it be 4000K or the 4500K. According to the R9080 chart the sw45 (4500K) look very promising. The tint chart has it shifted more toward the red spectrum unlike the other temps (4000K, 3500K etc).

Very true. :slight_smile:

This is indeed über. Compared to the good ol' 219Bs, increased power/current handling and efficiency for close to double the peak light output, coupled with even lower Vf…

This is a reeeally nice upgrade for lots of inexpensive flashlights, capable of transforming a dud into a jaw-dropping experience. Top notch WOW factor! :LOVE:

This is even more amazing than…

Sorry for the sheesy joke!

Kudos to Nichia.

Cheers ^:)

Texas_Ace, thanks for data!

Anybody build a triple 219C yet?

I keep meaning to but have not had the time. Now I am almost out of LED’s so not sure if I will be able to till the next shipment arrives.

+1, thank you TA!

My first triple is in the works. Stacked a 105D yesterday for ~ 5.4 A.

Tuesday I have time for building a triple, but it will be with the sm353.

Remember, the manufactures reccomedations for max current are all base on non DTP attachments. Sure, we overdrive them beyond what they might be rated at even if they were spec’d on DTP copper but we couldn’t achieve what we do if those specs were absolutes.

Yup, and I love it in a trip. I used 20 awg wires and removed tail bypass to get it down to 11.55 amps. It started at over 16, to much for a titanium host.

Waiting for drivers here, but will soon do a triple 219C 4000K in a Convoy S2+
I’ll be using 16x 7135.

Well, I went for 16x AMC7135 now. But I don’t know if I’ll leave it that way, this drivers gets freaking hot. No wonder though, about 5W or more getting dissipated. Have to do some more testing. Not a good idea to use high drain 18650’s, obviously…

Where are you getting the high 7135 count drivers? Mountain Electronics?

I stacked a Nanjg 105D with 8 additional chips.

They need their cooling too.
But when the battery lowers towards Vf of the LED (s) they won’t get hot anymore.

yup, I tested with fully charged LG HE4, not what I’ll be using in the finished light. Will use a protected 3500mAh cell, so the excess voltage won’t be that high.

Hmm… then the battery will get warmer due to its internal resistance…
So what’s worse? :slight_smile:

The modern 3500mAh cells should have no problem with that current. I think it’s better the whole cell gets warm a bit from within than having the driver in front of it running hot over 90°C.

Comparison with the 219C D320 5000k 70CRI emitter:

Thanks for the comparison chart!

Just to clarify, this is a D240 bin against the D320?
Chart mentions D240 but Thread title says D260?

I assume it’s the D240 as that is what clemence had gotten. :+1:

EDIT: according to the output numbers at 1A and 1.5A the D320 acts more like a D300 bin.
