2000k flashlight

does anyone know if there are any flashlights ready to buy with a 2000K color temp, preferably with a high CRI? thanks!

I guess the lowest I’ve seen are 2700k. I’d like to know also if there is one. Not sure I would like it though. Maybe way too much yellow. 3500k is what I like the most. 4000k would be second.

The JetuE21A from Clemence (Virence.com) can be had in 90+CRI 2000K - unfortunately looks like it’s currently out of stock though.

The 2000k e21a mentioned above have an outstanding tint that teminds me of a very deep sunset. There are yellowish tints around but not that one

I agree with ma tumba. The tint on Tuesday 2000K E21A is excellent. I believe Clemence still sells the boards with the emitters in a quad configuration. I used that in a copper S2+ in a custom build. If you were really up for it, you might be able to do a custom build, but keep in mind the board is a bit of a pain to work with in a compact host. Unfortunately not a ready to buy option. However, Simon at Convoy now does the 2700K SST-20 in the Convoy S2+ that I’d about the next closest thing I’ve found to the 2000K E21A, for HONDARIDER.

i saw the virence 2000k a few days ago but it went out of stock, and he’s not sure if he will bring them back. i wonder if i should just attempt a custom build, if so, i have lots of reading ahead of me. i did see the convoy 2700k sst-20 a week ago and i picked up one of those. not too many other options besides those it seems like eh?

There is the Sofirn SF-36W, but it has a bad beam, and middling tint. It is not as warm as the 2700K SST-20. There are quite a few 3000K SST-20 choices like the D4S, M43, and upcoming D18. Those have a CCT just as warm as the Sofirn, but much better light qualities. The guy who runs emisar/intl-outdoor ,Hank Wang, might be able to do a custom build with the 2700K SST-20’s if that turns out to be warm enough for your needs and you want to pursue higher powered lights.

Unfortunately not a whole lot of non-DIY options for the ultra-warm CCT at the moment. Another emitter option for the DIY route would be the ultra-warm CCT Luminus Cube 1800K. I do have a board for a couple of the 1800K Luminus Cubes I’m waiting on to run in parallel, and we’ll see how those go when I get them into an S3. I tried the 2200K XT-E, but that was 80 CRI didn’t deliver its promised CCT and looked horrible in orange peel optics.

Where can they be found?

I like E21A 2000K, 1800K should be even more interesting)

Andrey, please make a groupbuy for EA 21A 2.000K or 1.800K! That would be awesome! :smiley:

I would buy an 1800K E21A in a heartbeat, but I think the warmest CCT they come in is 2000K.

The Luminus Cube in 1800K 90 CRI is available on Mouser , but you need a board like this to fit the small footprint of the Cube. I have that board on order. At this point it’s the main thing I am waiting for. I plan to run two of the 1800K emitters in parallel at just over 1000 milliamps. I’m still a bit undecided on the optics, maybe an LEDil Boom-s? I think that and an 18350 tube might be in my future.

There is no E21A 1800K, I mean Luminus Cube 1800K.
E21A can be found at virence.com .

Thanks! I think 4*1.6mm led can be fitted at 3.5mm board or 5mm board.

Would that be a 2s2p wiring? We might need a boost driver for that.

No, I mean the same idea as for Optisolis.

Central pad now is not neutral , original “+” and “-” are connected.

So both the outer pads become hot+ and the thermal isolation pad becomes negative-? I hadn’t thought of that! That looks like a better idea, more of those ultra-warm lumens, and a better fit for optics

Did you ever get the Luminous cube in 1800K to work? Quite interested in that one now that I’ve modded something already

Heck yeah I got it to work. :slight_smile: I used the board from Clemence since that 3535 quad board technique that makes the center DTP pad the - ended up tripping up any driver UI I had installed. It’s amber toned, definitely. It makes my 2000K E21A look like a regular warm white household bulb even though it’s something very different. Almost feels like LPS/SOX levels of warmth, but with the color rendering turned on. This is when compared to my NBA LED. I might give the 2200K cube a shot next, but maybe use a different board. I’m currently feeding the two Cube emitters in parallel with a 1.4 amp driver.

I don’t know if the Luminus Cube will center well on it but there are MCPCB for Cree XQ-E that is also a 1616 LED.

Wow awesome. I want one now. Is there a good place to learn about LED compatibilities with mcpcb and voltage etc?

Would I be able to put the luminous cube in an armytek wizard pro? it’s 12V

also what light did you end up using as the host? Clemence is currently out of stock on the mcpcb. :confused:

Yes, those boards for the XQ-E should work. The Cube and the XQ-E have nearly identical footprints, essentially like a zero ohm SMD jumper almost. Pretty easy to get solder paste on and reflow because of no separate thermal pad in the middle.

Are those boards running those emitters in parallel? Do you have to address each emitter individually or can you run them all off of one set of positive and negative leads? The second board should fit in something like a Convoy M1/M2/S11, but would need an XP-E size centering ring for the optics to fit properly. You can still get by without the ring. The first board would work in any of those hosts, but would need a spacer for the compact TIR optics to fit. Those boards are unfortunately a little too big to squeeze into an S2+ shorty.

For a 12 volt light you would need 4 of the Luminus Cubes in series. That second board Talley-Ho linked, if that came in a 4 series setup, that could be a candidate for your host. You would need to make sure the width of the MCPCB would fit.

Manufacturer specificication sheets for forward drive voltage and compatible footprints. Website specifications for MCPCB size; footprint compatibility; and operation type, like 4 series, 2 series operation and so on. Confirming those two pieces of information match will give us our compatibility. Sometimes, we can bend the rules a bit and use something like a 3030 footprint LED on a 3535 footprint. That information is gained from experience.

I ended up using a Convoy S3, so I could easily play around with different optics.
