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 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?
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 “.
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.
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.
