1800K LED? Isn’t that a bit too orange? :confounded:

Candle light is 1800K. Very warm and cozy. Too bad it is above the BBL.

Apparently at 1800K, tints above the BBL are fine, I can see nothing bad about the tint whatsoever, just: campfire

DavidEF · 2019-07-23T21:55:04.000Z

So, a low fire, like a candle or a campfire, is around 1800K? Well, I guess that’s not so bad! I love fire!

I really like your reviews! I think you are the only person who does LEDs reviews??

It's weird how the led in the picture above looks very very nice but in reality it will look very orange..

I like it though:)

I really wish to see your flashlights collection one day! I think you have amazing collection of high CRI lights???

God knows what kind of high CRI lights you have! :-)

djozz · 2019-07-24T09:32:01.000Z

There are a few other led reviewers, maukka does some, and for a short period koef3 has posted a few. They both are better equipped than me.

Yes, I have quite a collection of high CRI flashlights now, but the hosts are usually the typical BLF lights. My most used high CRI flashlight is a cheap no-name tiny 16340 tail-clicky host from Fasttech, with a BLF-A6 driver and 3000K SST-20 and a lighted tail. (the lighted tail is 95CRI btw )

Btw, these Cube leds will make a fine lighted tail too.

DavidEF · 2019-07-24T15:31:35.000Z

Oh, I hadn’t thought of using these in lighted tail switch PCB’s! I wonder what it would look like to put these behind a pink button cover. With the extremely low CCT and high CRI, it should look really nice!

Nichia · 2019-07-24T15:53:03.000Z

Even tailcap LEDs is high CRI??!!! You are crazy! Just like me! lol

Nichia · 2019-07-24T15:54:18.000Z

Now I will keep thinking about the light you mentioned can we some pictures if possible please?

Someone should make a tiny beside ‘candle’ with this led!

SKV89 · 2019-07-24T18:31:58.000Z

The E21A 2000K with DUV of 0.000 is a great candle light too. It’s just slightly cooler temp than an actual candle but you get neutral DUV tint and 9090 color rendering. I love all of my E21A 2000K modded lights. Great night time lights.

For candlelight colour lovers there is nothing not to like about the 2000K E21A, it is a wonderful led. The one thing that this Cube does better is the price of just 12 dollarcents per led, it opens up applications that you would not normally use expensive E21A’s for, like use in lighted switches.

SKV89 · 2019-07-24T19:07:49.000Z

Good point. I hope LED4Power or Lexel would start offering these in their lighted switches

Very interesting, thanks djozz

Not much to see about it, the host was small (D25C-size), cheap and it looks cheap and used. I just rebuild it to the mentioned specs and to the point that it is very reliable, it always seems to work. The lighted tail are 3x Cree XD16 2700K 80CRI, and 3x 633nm red 0603 leds. The added red to the XD16 light brings the CCT to 2200K and the CRI to 95. Not that there is enough light in the tail to see that good colour rendering at all, but it is the idea that counts.

Nice job! These are interesting emitters for sure.

Agro · 2019-07-25T12:37:58.000Z

Thanks djozz.

I see that you ordered a 1616-1103 and not 1616-1100. Yours is specced to have 135 degree emission angle as opposed to 170 degree of the other. I see that there’s even some light going back towards the MCPCB but the photo doesn’t seem to allow me to judge whether there’s much of it…Could you comment on the emission pattern?

You pay more attention to details than me obviously, I had not even noticed that there are two designs of the Cube.

I would have to dive into it but if I have to guess, the 1100 has a higher block of silicon/phosfor than the 1103, thus looking more like an actual cube and for that reason emitting more to the side than the rather flat 1103 that is in the test above.

Btw, the 1100 is not sold in 1800K, the lowest CCT that Mouser sells is 2700K.

Nice djozz, be interesting to see that one attached to Anduril in Candlelight mode.

And how can y’all forget the EXTENSIVE list CRX puts out? HERE
