Active again: Nichia 219CT 4000K R9050 high CRI LED (and some trits)

Hi Rey, 4 Nichias arrived, 2 to come.

Question about the driver you offer:
Is this the upgraded one with high PWM frequency?

It is the 1st batch. 2K Hz

Bump.

Got my emitters today, thanks a bunch!

Rey, I can’t get over how beautiful this 219C emitter is. Want!

Are they still individually available? Thanks.

Rey, just received the LEDs plus drivers. Thank you. My EDC is now brass! Like very much

Interested in the driver.
Would it operate in a 2xAA host?
Approximately, what would the currents be?

Still available, thanks.

Technically it will do. Below is a test from DB Custom.

Testing showed the following results using a new Alkaline Copper Top 1.5V cell…

LevelCurrent__Lumens
1…………0.003A…….0.069
2…………0.047A…….4.002
3…………0.391A……30.774
4…………1.325A……86.94

Energizer Lithium Primary 1.5V

LevelCurrent__Lumens
1……….0.003A………0.00 on the meter
2……….0.044A………2.09
3……….0.389A…….33.496
4……….1.323A……106.95

And with a freshly charged dark purple Efest 14500 650mAh cell…

LevelCurrent__Lumens
1…………0.001A………0.00345 (firefly, barely glowing)
2…………0.063A……10.212
3…………0.477A……96.945
4…………1.83A……362.25

Received the eight leds; tint is very very nice, not yelowish, uniform throughout the light beam, not warm, not cold, perfect tint for me. Thaks Rei,

Thank you.

Got mine as well - haven’t put them in a light yet but love this one in the Pineapple; Thanks Rey

Hi Rey,
How are you on LED’s, drivers ?
Also I know you won’t recall but on the other thread I raised some questions regarding rings in the reflector beam shot and sent you a pic of what I was talking about and you thought it was brass reflections?
Well just read your update on the OP about the reflectors.
Can I place an order if LED and all are still available and request 2 reflectors for my lights? All one shipment maybe?
I knew it was that reflector, I wet sanded one and improved it a lot but doesn’t look quit like you perfect beam shot.
Thanks Rey

Rey,

Got mine in a few weeks back, and with some help from RMM at Mountain Electronics, I now have 12 of these in a M43 Noctigon Meteor!!

As others have said, the tint is beautiful and even, the high CRI makes the 5500+ lumen flood fantastic with colors… Sincerely appreciate your offering of these here!

Any members here that have not tried Nichia emitters or high CRI or 4000K tint range, do yourself a favor and pick up a couple of these. This is a fantastic emitter for $4.

Now that is a light I’m really jealous of! Nice!

Question, something I’m really curious of and you may have the answer with all those leds in one light:
If you set the Meteor very low, you can see all those 219c high CRI leds simultaniously: since these leds are not binned very tight (I guess they are 5-step McAdam), do you see much tint variation at all in reality?

They are awesome in a triple, but they pull 11.55 amps in my triple with a good battery! They get very hot and they get there very quickly. This is the best Nichia tint I have seen yet. I think Rey told me they are D260 SW405 emitters.

I will take more of these… pm inbound!

Interesting you get such low current. I generally get 16-20 amps out of a triple 219C. Are you using thin wires? What driver?

Interested in what you mean by ‘best tint’?
Do these 4000K have more red in tint than other 4000K you’ve used?
Have you also tried Clemence’s 4000K 219C?

I’m trying to find some with the most red in the tint.

Thanks!

Hey Ace, was over 16 to start with in a Ti host… removed bypasses and dropped to 20 gauge to control current and heat! Mountain 17DDm new driver with bistro. 11.5 seems fairly friendly in that light. Do not want to cook it!
