I was also interested in the 2200K-2000K E21A’s, but Sofirn supposedly had issues with sourcing them.

As my flashlight taste palate evolved, I no longer like lights I purchased in the past due to the color temp. I have an SP36-pro that has 6500k emitters. I want to replace it and noticed the offer a 2000K emitter choice which I think is the E21. I have diffusers for the SP36 and I reckon with the uber warm E21’s, it might make a good tailstand 5600lm little lantern. Not that you would run it on turbo but turned right down on candle setting and it would be pretty nice.

I going to order another LT1…in that hawt orange color. But…I notice they are advertising the new updated Anduril 2 version, it’s significantly more expensive. Is there any difference other than the Anduril? I like my LT1 just the way it is I don’t want any new fancy more complicated UI, it took me long enough to master Anduril-V1. So is it just the programming that is different?

No, the new LT1 version also functions as a USB-C powerbank. Even using a nice standard compliant chip

The actual flashlight circuitry is untouched compared to earlier versions, so you should be able to flash Anduril 1 onto it.

However, i would encourage you to give Anduril 2 a chance.
For basic uses, Anduril 2 is very similar and in many aspects more forgiving than Anduril 1.
More advanced uses do require some relearning of course.
I personally have reflashed all my lights to Anduril 2.

Thanks, I was looking at the Anduril 2 operation sheet today, I wonder if they increased the type C charge rate to PD18w spec, that for me would justify the cost increase for sure.

Interested. Not sure how to get added to the list. I haven’t read every page on the thread any idea what the price might be?

I added you to the list. I asked Barry for an estimate of the price and since they are close to making a prototype hopefully he’ll be able to provide a number.

Actually, I wish we could go even warmer than 2700K with the LT1-mini and LT2 (the even bigger one). For a cozy mood illumination, 1800K – 2200K like true candlelight would be a great add on to the warmer end of the tint ramp. Unfortunately, there are very few LEDs only in that spectrum, LH351D is not among them. 4× 26800 might be too big in diameter size. You would probably need two hands to hold this monster. Big Smile Moreover, these batteries are hard to source for manufacturers and even more difficult/expensive to replace by new batteries.

I’m not sure if there is a High-CRI LED in that range of tint of 1800K, but its probably not a big issue when its that warm close to a candle light color.

It might be awhile before we get true candlelight CCT emitters but I’d love it if we could get 2000k E21A as a new low end CCT

Very true, Maybe sacrificing a bit of CRI to have a candle tint glow at it’s warmest setting is fine. I have some random-brand LEDs in modified lanterns in the 1800 ~ 2000K range, and love the near candle flame color tints, regardless of the lower CRI, and its not really noticeable when they get into that flame yellow range.

BLF member rngwn has had 1900K 5mm leds made with wonderful tint and CRI (1900K, 93CRI, duv -0.0010, I recommend these btw, he has many still for sale in his thread). I’m not saying that these should be used for the little lantern (at 10 lumen max per led you need too many of them), but apparently there are chinese led manufacturers willing to custom make leds with special tints, at low quantities (rngwn’s batch was 10,000 pieces). Maybe a route for the lantern?

Nichia recently added an 1800K, R9050 version of the E17A to their product listings:

http://www.nichia.co.jp/specification/products/led_spec/NCSLE17AT-E(6277)sm18x%20R9050.pdf

They are also supposed to have an 1800K version of the 219F coming out, which will be easier to work with due to the XP-sized package, but so far, only 70 CRI has been announced. It should still be far better than amber for imitating firelight.

1800k Nichia’s sound nice. When modding an LT1 any Chinese made led ‘you’ are happy with is just fine. But for off the shelf production I think USA or Japan made high quality emitters are a must. The LT1 has a sense of quality noticed by its users that is important. I think whatever DBSAR and Co come up with will sell, this lantern has a big following here and abroad.

Chinese emitters can be anything from very bad to as good as the known brands. For a lantern especially the tint is relevant and chinese leds can deliver some very good tints (like the high CRI Getian leds).

Sure maybe your right, the lantern also needs a decent max output that’s where I think the Chinese led’s may fail, also efficiency too. But I’m just a flashlight hack with little to minimal knowledge. I know what’s good when someone else has done all the hard work, wrapped it up in a cardboard box and slipped it into my letterbox. After that point I become an ‘expert’.

A lantern with E17A at 1800K and 4500K and tint mixing would really be perfect imho.

It would allow for a neutral 4500K light option, a candlelight/fire-like light option at 1800K and very rosy light at all CCTs in-between. If Sofirn cannot offer this, I would be happy with replacing the mcpcb if someone offered a replacement with these emitters already reflowed. Maybe there will be a market for such an offering.

There have been recent PM’s with Barry and along with designs from Sofirn. It’s great that DBSAR has been able to get back into the mini, and even greater that his health and situation allows him to do so Thumbs Up

In my opinion we’re close to getting to the final design and thus closer to production.

Ah, very cool that his situation has improved. Hope to receive this awesome light soon! Keep up the awesome work!

OP Updated, Aug,17,2021

Some news for everyone interested in this LT1-Mini project! The team is well underway with the design & development of the BLF/Sofirn LT1-Mini! While DBSAR has been going through a big move & life’s change, he is slowly getting re-settled in a new home, and getting back into work of things on these lantern projects. In this case, LT1 team member Lux-Perpetua have stepped in to really help push this project forward with a finalized design for the mini LT1 lantern. Barry of Sofirn is with us 100% on the team to get this into testing phase and production soon!

That’s very exciting, congratulations!

I hope the warmest tint will be 2000K or warmer. I never go higher than the warm end of the ramp, 2700K, on my full-size LT1!
