Pity there’s no cyan / turquoise samples in between blue and green there.
No purple either…

That’s all I could get from the paint store. Next time I’ll try to get more complete colour cards. Took me 2 hours just to get them glued evenly. But now we know that UV plays important role in making anything looks more natural, something not included in CRI colour sample.

You’re fast! Those are many shipments you packed there!
Have fun with the soldering Tex :smiley:

It comes from experience I guess. Having been doing internet sales for some time you learn a few tricks to speed up the process.

Luckily everyone on BLF sent payment correctly with all the needed information included with it, this saves me a ton of time. Thanks for ya’lls part in that!

Do you think they’ll still let you in without buying paint? :smiley:

That’s a big can of worms you opened there. Thankfully, my windows filter UV so I can just stay inside and ignore the whole thing :wink:

So will the next step in high CRI be to add a UV emitter next to those nichia? I can picture people bragging about how fast their light gives them sunburn.

You know, UV ist not so great for the eyes. I would wear sunglasses outside in the tropics. The picture with sunlight would probably be very similar to the one from the 573 Nichia with a UV-Filter in front of the lens(Red, deep blue and Cyan color will still be better though).

Sure, he’s my friend. I can get all the unused colour cards he has. Unfortunately those are also the least complete too. Less card with more complete colour samples should be better.

I think it’s mainly caused by the glue spray I used. I wiped the excess sticky stuff on the cards with wet towel, thus the smear marks. Some materials respond stronger to UV.

Please don’t, high CRI minus the UV is much better for our eyes

Actually the cool white 144A has the highest violet-blue (480nm) spectrum proportion compared the other high CRI Nichias (> than 40%). But still far away from the UV region

O… Sorry…
GREAT job, Clemence !! :partying_face:

I think we’re looking for a “color wheel” though:

BUT, when you print it it will be made up of yellow, red and blue, so that wouldn’t work either…

Maukka probably knows what you would need.

Hmmm…
So basically true daylight from an LED would also need UV then…
Cyan is difficult too.
That would mean you have to add a 400nm LED and a cyan LED to it…
And while you’re at it, still a little more deep red…
:person_facepalming:

I think i’ll settle for Nichias… :partying_face:

But maybe interesting for EU members:

I meant that sunlight is still better which is no suprise.

It can be whiter than sunlight though, because sunlight has some narrow bands missing, the ‘Frauenhofer field lines’ i.i.r.c.

Was not expecting a tracking notification from you this soon! Awesome, thanks.

Yeah, I’m just wondering how the stuff outdoors responds to it. It must have at least a small effect on some surfaces.

Don’t worry, I wouldn’t do something that stupid. Those LEDs are good enough for me. I just wish I could easily light the whole house with them.

:smiley:

For the people who bought the leds via me:

Sorry guys, the package from Clemence to me is stuck somewhere in the Netherlands since last sunday. 17track.net says ‘on hold’, Postnl does not recognise the barcode (yet). Could be hold up by customs, I don’t know.

I hate to be in this position, I owe $600 worth of leds to people that I want to deliver and the mail holds the package at an unknown place for unknown reason, even though it was carefully sent by Clemence (and payed for by me) trackable, insured and as an EMS package for priority.

I sometimes think that as long as you send stuff as an unmarked untracked and uninsured package, it arrives without problems and on time, and if you want the mail to care about the delivery, the whole process slows down and the package gets stuck in random places.

I feel bad to make it “marked” but I didn’t want to just send USD600 worth of package without a clear declaration to the post office. I do hope it’s held by the custom rather than lost. I put your number on the package Jos, they should call you when it’s sorted out.

- Clemence

Edited: tracking number blurred

Don’t worry and don’t feel bad Jos. Nobody here is going to hold it against you because delay is not fault and situation is out of your hands at this moment.

Hi djozz, I sent you PM other day, about my payment!

sorry, answered :slight_smile:
