What kind of optic is appropriate for the 144A? I know some of the first 6V samples had pretty impressive egg yolk, but my recent samples still make a huge yellow-green dot with a clear TIR optic (the famously crappy stock Prime one).
Seriously? That’s positively… weird.
So it’s not just a Save Energy Day, but somewhat religious? Interesting…
I could use something like that around here, though. Nice change of pace…
Well, minus the beatings.
You want a beaded Tir optic for that emitter, it works wounders. The floodier varieties give better tint mixing.

Funny you mention that, ’cause I got a few LED lanterns from Amazon for exactly that, swapping out the craptastic Angry Blue™ LEDs with some nice 2000K LEDs scavenged from strip-lights.
No flicker, gonna use it probably with the come-with “volume control” circuit, or at least just the potentiometer from it.
I should have mentioned I’ve used beaded optics and it does look perfectly fine with them, but they aren’t as throwy as the clear ones. It seems like unless there is quite a bit of mixing, you get that huge yellow blob, so clear optics are out.
My take on catching the tint of the E21A sm203 R9050. I corrected the image a bit to match what I see in reality, not exactly right but close.

Thanks guys, nice pics! It really does seem very similar.
Now I’m really thinking about modding that Novatac.
It would also be great for a table lamp when BBQing.
Oh, you did something with that LED… kewl!
I remember you mentioning the Stanley, goggled all around trying to find somewhere to get some. Only RS in the UK had any, but shipping would’ve been obscene (and USD→UKP even worse), and Mouser or whoever was supposed to have some locally, had 0 stock and no resupply in the foreseeable future.
So I hit AX and grabbed pretty much anything that said “2000K”. 
The Cree XP-E2 can be had with 2200K. It can even be de-domed to get around 1700K! But it’s not available with high-cri, if I recall correctly.
No worries. I got something like 100 LEDs on the strip-light, so I’m good.
Lumileds has 2200K Z ES LED, 80CRI, available at Mouser:

I ahve some 20mm MosX boards for Z ES, but I still don't have it uploaded on my page.
Just put the 2000K into ultrafire uf10. What a great sunset tint! Not sure it is very useful in any real world application but looks just gorgeous. It may end up in a headlamp for bedside service.
Clemence, thanks again for making these e21s available. Most of them are beyond great.
“Bedside Service” :heart_eyes:
And here’s another little sunset. It suits the copper light very well I think 
This is indeed very sexy for your bedside service Djozz. Looks like a pocket candle

The setting on the picture is 1.5 lumen, so 1/10 the light output of a candle which is rather perfect for night use in my son’s bedroom when we stay the night somewhere else (myself I prefer no light at all at night), the runtime should be about 100 hours on a battery load.
Yes, it should get along very well with copper. And yes, this CCT is great for very low lumens so I am wondering if there is a nice twisty AAA host with a firefly mode, where the board can be installed after heavy sandung. Like, Fenix E05 form factor, but with a <~1lm lowest mode
I usually put a ping pong ball or any white milky plastic bottle on my EDC to get more of the lights directed to the table when outside (dim cafe or restaurant). And use it ceiling bounced in the room or tent.

I just played and tested a Tiny 26650 DQG for Pavlo. Saw some of the smallest EDC in George’s collection. I plan to get some for myself. Maybe I’m late at this but just amazed at how he boosted single 26650 to feed 7x XPG2 at 1A.
His smaller EDCs could be a great host for this 2000K
- Clemence
I have a Spy waiting for an Optisolis. Actually it is waiting for Arctic Alumina, which I will cover the central pad with to avoid grounding of the LED.
I just recalled that you installed some e21s to E05, didn’t you? Did you use your boards?
