Does anyone have an experience with buying from Beijing Yuji's High CRI led webstore?

From my conversations with yuji they make phosphors. They’ve got contacts to make the LEDs and more so to make the modules.

The entry to get decent cost savings is around a few thousand which isn’t that much.

I do high cri hi colour temp… And so far they’re the only integrated single phosphor I see.

I would absolutely kill to have a remote phosphor 6500k violet pumped diode.

I can’t found any independent tests of Yuji LEDs, only 1 forum measurement.
And Yuji not sell CC (constant current) modules with all types of LEDs - only “if you ’ll buy 50 pcs modules of each color temp.”.

I’m going to defend Yuji here a little bit- they sell phosphors. The modules they offer aren’t the best- their modules are for demonstrations- but they ARE very nicely built, thick aluminum, robust wire-insert connectors. I suppose you could gang 2x or 3x into a strip light if you wanted to and minimize additional manufacturing time- I’m personally working on designing some bars.

They were responsive about adding a ‘sampler pack’ of various dies and color temps. I wish they’d include a 1900K unit but I’m good with the 2700k.

Just an opinion. I like their stuff… and I’m pretty picky.

what about bridgelux Vero decor series, they have a 2700 and 3000 K CCT with 97 CRI also 5600 K CCT with 90 CRI, i bought them from Digikey for lighting my Aquarium why buy unknown brand while you can buy a well know brand and much much much cheaper

i got the Vero 18 Decor with 5600 K CCT with 90 CRI it is about 70 Watts for 16$ only

I love bridgelux . they don’t have high color temp high cri diodes though.

Is there is in the world a 6500 K CCT LED Emitter with 90 CRI or higher, if yes give a link please

Uhhhh… Yuji makes one. I’d use 1:1 vtc and btc pumped diodes.

Cree advertised one in their spec but if it was manufactured I couldn’t find it not request samples.

I have 4 of their warm white high CRI 5mm LEDs. I would love to buy more, but would never use 100 of them. Are any others interested in splitting an order?

Yes, interested. Have you gone through check out far enough to see how much shipping to you would be?

Shipping to the US is around 16 bux. If there were enough interest in the WW and NW, or even just the WW I would love to see this come together.

Sampler pack of modules ?
You buy it ? What minimum quantity of each color temp ?
2 month ago I received answer ” minimum quantity =5 for constant voltage option “(with resistors) and ” minimum quantity =50 (!) for constant current option “.

does Yuji make LEDs for an 18650 light?.
The only one I’m seeing coming is from Cree in a ZL at 95cri 5000k

Yuji does not make small high power leds (yet), just mid-power and COB leds. I think that making leds with a high illuminance requires special skills that not every manufacturer has.

And 10000 lumens, 5500K, 90CRI for <$50 single quantity.

Hi
So what’s the chances of yuji making LEDs for flashlights ?.
I’m really after a 5600k hcri for an 18650.
What do you think Djozz?.

Thanks.

The XP-G3 is available in High CRI (>90) all the way up to 6000K or 6500K.

I have some of the 5000K High CRI, they are very nice. Cutter sells them, not sure if they’re OOS at the moment or in stock.

Thanks
You got a link for xpg 3 - maybe a 5700 or 6000 80/90cri please?.
Thanks.

Here’s a 5000K, >90 CRI, R3 flux, XP-G3. No info on specific tint bin.

Here’s a 5700K, >90 CRI, R3 flux, XP-G3. Same as before, tint lottery

Amazingly, I can find the 6000K 90 CRI, even the 6500K 90 CRI. But with a MOQ of 1000 @ .70-80¢ each, non-stocked but available with an 8 week factory lead time.

I need to order some of the 5700K just to satisfy my curiosity lol!

How in the heck do you search arrow? I can not figure out how to narrow the search to any of the Cree LED’s that we are interested in here. They have free shipping this month apparently and I would like to grab a few high CRI LED’s in the ~4000k range.

They are one of the hardest to figure out search/inventory systems I have seen.

Dear Darry,

Thank you for your inquiry. My name is Nicklaus who is a representative of Yuji Group.

We do not have plans for flashlight LEDs.

I have attached our Brochure for you, please have look.

Have a nice day.
