I've been wanting to try the Yuji high colour rendering index LEDs for a while, so when they offered me some I thought it would be a good idea to upgrade the bench lighting with them so we can all benefit from their much richer colour spectrum.
These LEDs use a complex phosphor system including high resilience and high output red phosphors that give a much broader spectrum than normal LEDs. This makes them ideal for film and TV work, and other applications like galleries where the better colour definition is advantageous. You can see Yuji's technology on their website at:-

Note that the LEDs are aimed at the professional media markets and cost a lot more than standard LEDs.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

I wish this was a mandatory test on road headlights… serious issue. High intensity doesn't mean best visibility!
Been wanting to find some very high CRI LED strips(particularly with saturated reds) for mounting under the cabinets, above my stove.
Yuji was my first pick, but the prices are expensive.
What was the old CRI?
Yuji sending you those COBs was a stroke of brilliance (pun intended). I was on the fence with spending the seemingly exorbitant amount of money on a set, but then saw that you did this, and it well pushed me over.
Top vid…but what colour temp leds are both of them
Buying these for my house, the lack of red in the big box store brands gives a bright but dim look everywhere, I hate it
funny how it's easier to just have non-halogen incandescent bulb instead of trying hard and still failing at cri… i play with leds but i don't light my house with them, especially in my work area, it's just not worth all the hassle… all the super expensive materials, the failure-prone components, to achieve poor light… what a great way to "save"…
Sadly no real difference for me but I’m color blind lol
I see they have some nice 36W E27 bulbs for 40$, but the shipping is 50$.. too expensive for me. Unless they get lower shipping rates, or some distributor in Europe, most people over this side of the world, won't buy. I don't mind to wait longer and pay a lot less on shipping
Very well done, Clive ! Just a note ; Color with light,, and color with pigment are two different things.
For example, all light colors make white, whereas all pigment colors (ink, paint, etc.) make a yukky color.
Conversely white light can be refracted into a rainbow of colors but pigments have no such property. So I found it very interesting that you used an ink printed spectrum (pigment) to explain LEDs/phosphor ( light). Very cool !!
High CRI is a beautiful thing. Gotta love a light as close as possible to natural sunlight without clouds 🙂
I got two Yuji LEDs because of this video. One of them died recently but Yuji customer support is excellent and they sent me a new one.
