New bench lighting with Yuji high CRI LEDs. 

Much better visually! Welcome to the Yuji-club! :)

Glad that you are consistently saying 'wavelength' in this video, Clive, instead of mixing 'wavelength' and 'frequency' as if they were interchangeable.

Wow such a vivid difference! Excellent thank you Clive! Looking forward to see your videos looking much richer!

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.

I'm in a lucky position to have a calibrated monitor and TV. The difference is noticeable and the new LEDs are certainly much better!

That's so much better Clive! How exciting!

Wow! That a spectacular difference. Good choice. 👍

Looking good Clive!

Wow! No wonder you got so excited when they offered them to you. They are fantastic. Also taut me the differences in lighting. Thanks Clive

Brilliant! Just when I thought there was no way for your videos to get better BAM! Thanks for the improvement!

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.

Thanks Yuji, better Clive vids from now on! :)

Looking forward to more videos. It does look much much better.

Watching Big Clive just got a lot more tolerable. Thanks Yuji.

It's one of those things you didn't know was wrote until you see the difference. Thanks man, good to know for my upclose project!

Yuji LEDs are pricey but damn good. I used their 50 watt warm-white chip in a battery-powered camp lantern with a light output I wanted to make look as close as possible to a propane lantern. It ended up looking better than I could've hoped--and bright as all get-out when it's running at full power!

I'm really glad you finally got around to replacing those horrible modules! One thing you might want to take a look at though: LEDs have their blue peak shifted quite a bit further to the right (the 450-460nm excitation types, that is) and consequently, they have a very large gap in the cyan part of their spectrum, around 485nm. Now the Yuji 98CRI LEDs use a phosphor for the >450nm wavelengths, as well as extending their output further into the reds, which does indeed make them a LOT better than standard LEDs (most of their spectrum is actually continuous, unlike the spikey phosphors which used to be used for CRTs, like you showed in the video). However they still have 2 very big disadvantages: They have a MUCH larger output around the UV-Violet crossover (400nm), especially in their 'daylight' 6500k models, which WILL eventually cause degradation of the colours (and in some cases even the base fabric/material itself) of the art/antique being illuminated by it, while also causing the LEDs own phosphors to degrade a bit quicker than normal as well. Secondly, they still have an extremely deep (and fairly wide as well...) notch in their emission spectrum, around the 420nm region, even in the very 'blue rich' 6500k type. (I honestly don't understand why people think D65 looks like noon sunlight? Is it maybe only supposed to emulate completely overcast conditions, but people just started using it for direct sunlight as well? Maybe my eyes are just defective, but when I compare properly attenuated sunlight with a 6500k source, the latter is blue shifted a LOT!) As for their 2700k LEDs, I understand that they choose not to do so, for efficiency reasons, but I really wish they would actually fill up the rest of the red spectrum to at least 680nm (but preferably to the full 700nm). It is indeed MUCH better than standard LEDs, but the CRI of 98 kind of makes it seem like 98% of the spectrum matches that of a 2700k tungsten bulb, which is simply untrue. Especially with really deeply red foods (like red meats, vegetables and red wine) there is still quite a noticeable difference between a tungsten bulb and a 98CRI LED. And no, it is not something specific to Yuji, all the high-CRI bulb that I have tested, do fail in this regard. With a suitable UV-filter and violet-attenuator, the Yuji LEDs are actually the best all-round lighting solution that I have had the pleasure of testing.

I love high CRI lights. Looks great!

I really like the new lights!

Clive, Thank You "very much" for doing this video! I can't believe the high quality of there "20 Watt BC Series High CRI COB LED Panel" (2 Packs for only $30) The build quality is a 10 out of 10 I'm making several purchases early this morning. 5:30am here. I watched your video earlier but I crashed out for a while. Shane and I have alot of projects goin on here. I can't wait till he wakes up so I can play your video for him and show him the things we're going to buy! The prices are very reasonable for the high quality of the product! Thanks again!

Very nice led's, Big UP Yuji!

We love it, thank you for your consideration of the quality of your video productions.

I love the new COBs ... the colors look really good even on the cam. Thank you for this _WONDERFUL AND EXCELLENT_ tip! ;) Oh, any a happy new year! ;) Hacky

Looks like a real improvement to me. For those saying it's too "pinkish" in the latter part of the video: Clive is very pink.

Ooo, full spectrum bulbs! Good choice

In my opinion the new ones look great, and considering the industry Clive works in, I'll hazard a guess that he knows more about lighting than most people commenting. I think it's likely that most people are used to the old LEDs, so much so, that the new ones seem odd to them at first, in comparison.

Thanks for sharing. I was searching for really good 100W led module and I definitely buy one from Yuji.

I once borrowed a spectroscope and went around looking at different lamp fixtures, and you could definitely see the various spikes of the fluorescent lights

Cheers BigClive, I've been wanting some info on these High CRI LED lights for a while. Your desk looks a lot better...

cant believe you had low-CRI lights all the time... good to see that :D always looking forward to seeing more

I love high CRI in torches, very good especially walking in the woods.

High CRI is a beautiful thing. Gotta love a light as close as possible to natural sunlight without clouds :)

Dang, looks great!

That was Very Nice of Yuji. Thanks Yuji! Always nice to see Clive Happy. I would consider these Bright vs Warm or Cold. W0W - Quite a Loud Orange!

Yes Clive we really notice a difference when we're watching you on a 65in 4K TV.... ready to break out into a Debby Boone song You Light Up My Life...

Looks great!

I like the new leds. Pretty nice.

I did check out their website and products and wow! All I can say is I won't be swapping out all the bulbs in my house any time soon unless I win the lottery.

Amazing difference!

What an improvement CLive!! =)

Nice. I like the new, truer color.

Oh damn, that was impressive... now I'm reflecting on the light in my own videos. Time to start thinking about investing in an upgrade :)

Now I can see all of your mistakes in FULL COLOR! Love your videos.

Very nice! I've been thinking of getting some high CRI strip myself.

The difference between the two is fairly impressive... It's on-par with when I swapped the CFL above my desk out for a 70w ceramic Halide lamp, only without the giant brightness increase.

This was super interesting, I've been wondering about studio LED lighting, mostly because I watch RU-vidrs who use it. Now I know what to look for if I ever want to get something ;)

Your hands have never looked better :) Enjoyable video

Fascinating!

Super nice!

yay foxy likes anything orange ! yes I just thinking of the food being illuminated etc and how it looks !

Comparison test with resistor colour codes please. Beige, brown and blue resistor bodies. Does my head in sometimes. Have to test with a multimeter when red and brown are so "close".

The effects of changing lighting types were brought home to me many years ago. I did the effects for a production of Sweeney Todd with a local amateur group, in a theatre with conventional tungsten lighting (loads of pattern 23s & 123s and the like). Another group were very impressed with my fake blood and asked if I could make up a few pints for their production of the Scottish Play. What they didn't tell me was that they were performing outdoors. The local paper said they loved the surrealism of '...glowing yellow custard.', we hadn't tried it under their lighting and one of the dyes fluoresced because there was a high UV content.

I think the "shadow" cone in the bottom of the divider wall in the beginning was most telling. Nice video as allways! :)

Take it to bits!

Hooray for great lighting! #NICEHANDVEINS

I'm colorblind so one just looks brighter than the other. but I'm happy that you are happy!

Thanks, I am looking for leds like that!

These are also great for display cabinets!

White LED modules using violet emitters were first developed at GE back in 2007. They even built a plant in Schenectady NY to build the modules. They didn't sell very well, though.

It's like night and day, nice.

I much prefer the new lights... one thing I’d have liked to have seen tho was a pair of color wheels in place of the real tree camo photos to see how well it is rendering color relative to the old light. Still a welcome change and a great video as always, thanks Clive !!!

very educational today...well done//i can actually see the difference...who knew..i didnt..you did..

Can't wait.

What color temp. does this LED on the left has? 3000K, 4000K or 5000K?

So.... Yes! To the happy couple!

wow insain looks great !!!

I wonder if the differences would be visible on one of those small difraction gratings

I can't wait for my Yuji leds. I ordered mid-december but apparently paypal didn't give them my info. mistake corrected and they will be here in a day or two. these look awesome!

That is a really great difference! I have issues with LCD (led) screens since the yellow just always looks wrong. There seems to be lot of differences just between LEDs claiming to have over 80 CRI

The red and the yellow tools really pop!

Hi Clive! When you mentioned spectroscopy of the lights you reminded me of a phenomena that occurs with CDs and other non-coloured digital discs; that the indents in the film around the disc playing surface are so close together they act as a diffraction grating, which causes the rainbow effects you see under a light as you tilt the disc. Try it with a CFL, look carefully and instead of a continuous spectrum you see individual images of the bulb at the different colours the phosphor puts out, albeit quite distorted. Normally with a CFL I see a very deep blue image (probably from the UV), a cyan one, a pale green one, a dull orange one and a bright red one. It usually helps to close one eye but it's quite an incredible and fascinating effect that anyone can try! Keep up the good work!

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 !!

I like the new ones

Looking at the difference after RU-vid has done its stuff is still brilliant, also my friend could tell the difference without his glasses.

I want one of these high cri leds!

I see a bunch of opposing comments about which looked better.... I wonder if that's a similar thing to warm vs cols white where some parts of the world expect different colours.

One thing I really notice with the new lighting. The burn marks on your bench are absolutely popping. Lol!

Can you please show us the fixtures you use with these LEDs? So where does one buy these Yuji emitters?

I love my HighCRI flashlights.

That's what I respect about you. Like myself, you have ''working man's hands''.

glowing now clive

Citizen have been putting out 95+ CRI LED COBs for several years. I have a couple of lamps made of Citizens with Ra / CRI around 98 (warm 3000K and neutral 5000K) and they are really great.

when I changed an incandescent bulb here for a Philips 2700K warm white LED bulb it was great light but indeed it had a tad less red in it.

Would you repeat the side-by-side comparisons with the CFL and tungstens? Also, do the limitation of the CFLs also apply to standard Florescent?

Excellent explanation and demonstration, Clive. Thank-you. Are you able to show more of the spectra of the different lights in a future video?

I felt that the small inverted "V" section at the bottom of the screen during the beginning of the video looked the best. The new light does indeed bring out the color, but it looks to hide a little bit of detail. Softens the image. The right light has a very grey look, almost dingy, but lots of detail. Where the lights crossed each other gave a best of both, in my opinion.

do you have a video or article on your light fixtures?

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.

Used to have 98 CRI T8 fluorescent tubes, and they weren’t insanely expensive. I’m hoping that eventually I can have similar LED lights that I can afford. No reason but aesthetics. I had great hopes for the sulfur lamps made to glow with microwave stimulation, but they weren’t practical for most applications. Very high CRI, very smooth spectrum.

So, you give the new LEDs a... glowing recommendation...

Great to see these high power LEDs becoming available. It's nice to see colours as they should be especially if you're trying to read resistor bands, trace pastel shaded cabling etc. Here's my shameless plug which I'm not getting a penny from: The Nitecore NU20 CRI headtorch. It's small, light, tough and the most comfortable headtorch I've used. The non-CRI version is a few quid cheaper but in a blackout, you might find Redex in your Ribena!

Those LEDs do make a surprising difference and are much better by comparison. I would never have thought about high CRI lighting at all before this video. The colour balance may need some tweaking in post but I can't really speak to that myself. You might be able to use a colour reference sheet at some point to help with that, just to make sure everything is displayed as it's meant to be.

Damn! I'd like to have whole house lit with those LEDs.

I was thinking about getting one of their bulbs for my desk lamp and thought it would be good for when I’m painting and drawing. My concern is that other lights in the room that are cri 80 might ‘cancel’ out any benefit from the yuji bulb.

Very informative. New lights very good but a bit hot.

I found the CRI 90 Ikea warm white 6W LEDs lamps pretty good. Time for a few samples?

Clive could you please show off your installation of your lamp. Need to know which components(heatsink etc.) I would need to run them. I'm a painter n my room isn't floded with sunlight. Thanks

Top vid...but what colour temp leds are both of them

I like it too 👍😉

There are many ways to get excellent color rendition from LEDS. Phosphor combination is just one way.
