4. 2*26650 long tube(sleeve for 21700)

8. UI: Tail switch to power on / cut off

 

Concerning 4)

They told me 21700 would just fit but not recommended at all as cells would be tightly compressed. There is no word about 21700 batteries in the manual, nor are any sleeves supplied with the SP70. My personal opinion is that high-drain 21700 batteries like Molicell P42A or Samsung 40T would yield much more power than any Golisi S43 or PLB-55A cell, so it would be somehow sad to be limited to 26650 only.

Concerning 8)

Please excuse if I have not followed everything in this thread, so I do not know what UI we had agreed upon. According to the manual the SP70 will have an UI comparable to the one of the C8F, i.e. stepped modes and ramping mode one can switch in between by multiple clicks. Apparently, it's not something sophisticated as NarsilM, RampingIOS V3 or Andúril.

As far as I can tell the LED tint change away from 5350K – 5700K has just come out of the blue completely.

Actually, the change has come into the blue, that is, the blue spectrum of light. Silly Wink

But yes, I have to agree with those here who are disappointed about the tint change. I think that Sofirn is seriously underestimating the amount of “tint snobs” here on BLF, of which I am one of them. I would prefer something in the 4000K range, although I can still accept the 5000K range. But 6000K is ugly enough to my eyes to probably make me avoid purchasing it.

Refer to this may I ask why the retain ring was missing in the design ?


And with a retaining ring suddenly the 21700s fit?

The input that is given here is relevant, pointed and particular, but I wonder if the sales don’t bear out the need for smooth reflector lux numbers, mod-ability and more easy on the eye tints.

Remember that Olight sells a heck of a lot of lights in the cool to cold spectrum! I also wonder if people shop with certain specs in mind (MORE LUMENS!) and that’s what drives some companies to spec the CW emitters. Price is another factor and maybe the BLF-approved details add up to a light that’s not in line with the rest of Sofirn’s price points. Who knows?

Yeah, I’m sure that’s the overall market reality. Maybe I just have delusions of grandeur, but I thought that the whole point of making a “BLF” edition of this light was to cater to our personal preferences, which appear to be overwhelmingly in favor of neutral tints. Of course we’re a small drop in the bucket compared to the overall market, but nevertheless I’m sure they could make some nice profit by targeting us as a specific niche.

Good points really. When you get right down to it, our BLF Wish Lists’ are just that I guess; “Wish Lists”. We are actually a very small part of the market as far as projected sales go & there is no way to cater to our individual varied ‘wants & needs’.
(because ‘we’ all think we’re right you know) Big Smile

However, once things are agreed upon; I wish those things would be done unless there is a very compelling reason to change.

I’m a bit irritated that people keep jumping to conclusions.

Tint has not been finalized. Sofirn is looking for 5350-5700K right now and should tell us soon (maybe next couple of days) if they can get it and how much extra time it might take.

Working with a company to design a light is a collaborative effort. It’s a combination of ideas from both parties. It’s not like BLF is in charge and makes all the decisions.

Hopefully, together we will make a really nice light. Party

My bad about the nickel vs steel issue concerning magnetism. I learned that nickel is magnetic, so, goes to prove, old dogs remain stubborn but CAN learn something new occasionally. Wink

Since this light started out as a design element of BLF requirements and is still listed as a BLF Special, it would only make sense that it meet BLF requirements. They’ve surely had ample opportunity since the tint was sorted out to acquire the necessary emitters, months and months!

In the end they lose sales here, and the interest to assist them in design parameters. But oh well, it is what it is… someone else will be willing to build what we want or just get lucky and get it right and then our money will follow…

We should start a group buy thread with current specs and see who is in. Money talks we will have a bit of wiggle room this way.

They obviously want the light to be out as quick as possible so they get there money back which is an issue for us because it means they have to rush certain aspects of the light.

As an example, I obviously haven’t built a lot of lights, but I can see how easy it is to cut off an 1/8” of threaded tube and run it into the head as a retaining ring, bingo, problem solved. No redesign necessary. There, that wasn’t so hard, was it? Wink

Yea the compelling reason here is money lol. It may be an extra few weeks wait on the LEDs after a few delays already. Peoples heads are on the chopping block lol.

Isn’t it fairly easy to swap the led to whatever color you want?

I was goofing around with some junk leds so I decided to swap their mcpcb. I used my cheap hot air station. It was much easier than I thought. Now I can do reflows. Big Smile

Congratulations Jason, being able to reflow your own favourite led makes you way less dependent on the manufacturers Smile Thumbs Up

But the idea of all past BLF special editions was to create flashlights that are right straight out of the box, not after modding.

Press fitted Tir in the S1 mini HCRI. X3 ruined his driver at disassemble.
UI and Lamp is nice, but a LED swap is hard.

I couldn’t agree with you more Jos.

At this point i don’t see any surplus value over a L6

This is not an “official” BLF light. It’s like a BLF edition.

You have to replace the led, driver and reflector on an L6 ($65 + $45 + labor). The SP70 should be good to go right out of the box.

Keep buying L6, though. They are good lights. Thumbs Up

I heard back from Tracy:

She says they had success in finding the 5350-5700K leds. I don’t know if it will delay anything or not. She sounded like they got lucky and found a supplier in Hong Kong.

The 21700 should fit “unofficially”. The manual will only say 18650 and 26650, though.

It is too late to add a retaining ring to the design. The first batch (for us at BLF) will not have any glue on the driver. I don’t know about later batches. Maybe eventually they will glue in the drivers.

I’m wondering if it might be better if later batches only used a tiny bit of weak glue on the battery tube with nothing on the driver. This should secure the driver in place, but might be easier for the enthusiast to loosen. IDK, just a thought.

Wish convoy was building this light, we would have tint choices up the wazoo! Anything over 5k is poop, 4k perfect. My sofirn Q8 is great for showing off, the oringin BLFQ8 is far superior in tint and real useage. Any humidity in the air renders the Sofirn Q8 as useless.

yeah i agree, its awful quiet on the convoy front, we have got an updated c8+ but still no l6+ wonder why.. guess the l6 sells still and is good enough for most people looking for a budget friendly light that does over 3000+ lumens on turbo and not breaking your wallet.

This (your second post in this thread) is nothing more than your opinion & preference.
Here is mine…. 4000K sux. Most anything under 4700K is pure crap…
……..yeah pure crap, as far as I am concerned.
And again, this is nothing more than my preference & opinion.

But the CCT of this light was decided months ago to be between 5350K & 5700K.
To gripe & whine about that now is nothing less than stupid.

And the builder of this light, Sofirn; was decided from the start.
To gripe & whine about that now is worse than stupid.

Don’t like it, don’t buy it. Plenty of people will……

Merry Christmas…… Thumbs Up

Convoy made XHP70.2 version L6 with SMO reflector on Aliexpress. I think driver is the same or a little boosted. Factory claims 4300 lumens. I hope this SP70 will be much brighter
