Does or does not? I thought Tom E said it goes to last used?

If my info is incorrect, I’ll happily correct it. I thought it went to last intensity used in ramping mode.

Edit: as I understood it, from OFF, press and hold goes to moonlight, and it will not ramp up to high like Narsil or Emisar’s UI. The only way to get out of moonlight is to turn it off, then single click ON which goes to the last used setting. For me, that seems like a shortcoming.

guys, I think there are some misunderstandings.

Sofirn SP70 available now is sofirn version which is helped by BLFers but not BLF version. Sofirn put it on market because sofirn need a big powerful light.

The BLF SP70 version is not confirmed, since now some of the sofirn SP70 are received by BLFers, you guys can talk about how do you like the BLF SP70 to be.

Just don’t mix sofirn SP70 with unconfirmed BLF SP70. Facepalm

You were describing a basic momorized level. When you single click to turn it On, you go to the last used setting.

So if you like to keep it at a specific level, you can. One click On and one click Off. It stays at that level.

Keep in mind that all UI’s are a compromise because you can’t please everyone. Even though the operation of Moonlight on the SP70 is not perfect, I think this is a solid improvement over the UI on the S70S and L6.

I personally don’t ever use lower levels on my big lights because I have smaller lights that are better for moonlight.

cool. package sent to Jason will arrive soon too.

pictures and video of SP70 sharing is welcome!

Guess it’s time to talk about a BLF version. maybe: retaining ring, smooth reflector, different tint, no switch tail cap, Anduril firmware? Big Smile

Could everyone read post 2000 again.

I’m guessing Sofirn would rather us talk about what we want than nit picking the current light and leaving a bunch of negative stuff for search engines to find.

I like Barry’s list. 4000k is ideal for me but its an easy change so I don’t really care.

Narsil would be better. No one is going to use candle mode with this and throwers aren’t really ToyKeeper’s thing. This is Tom’s domain.

Add in some input from Kawiboy, TA or Dale and this thing could be special.

Is it better if start a new thread for BLF SP70 ?

Do the sales figures of the current SP70 look good enough to make a BLF version?
Maybe it is too early to know?

I totally understand the “last mode” idea. In my opinion, it’s probably a good feature. The problem I see is the ramping from OFF. I cant ramp from OFF to HIGH. Ramping from OFF only goes into moonlight mode. Then you have to turn it off, then 1 click turns it to blindingly bright light.

Sofrin needs a ramping mode that goes from 0 to max, while holding the switch from OFF.

Yeah, this function was quite low on my list of priorities. I’m glad the overall UI works as well as it does.

A simple fix might be covering the lens with your hand or leg to avoid any sudden brightness while you ramp down.

A counterpoint could be that some people like that you can activate moonlight without loosing your preset level. Losing the preset certainly irritates me that’s why I use a different light when I need a very low level.

Like I said, no UI suites everyone perfectly.

I purchased this light thinking it was going to have ar glass and becu springs, but I’m not disappointed that I misunderstood. I like the sofirn lights I’ve purchased and would love to see an upgraded blf edition with a good price, I’d purchase another.

I was told that they were using BlueSwordM’s BeCu springs. Does anyone know how to confirm this?

@Scallywag, can you check if the springs are magnetic?

Thank you.


Speaking of magnetism…will a magnet in the tailcap be available as an option?

All is needed is a stronger magnet….

But really I was just kidding, I found the thought of carrying around a magnet this strong amusing. Smile

I don’t think so. BlueSwordM did give a good advice but engineers believed they can find great springs too. So……

Hope someone can compare these two kind of springs.

Awe man, that means the springs might be the cause of the lower amperage. I might bypass the springs instead of swapping the FET and see if the amps go up. I want to keep it stock for right now so I can do more measurements.

I have now created a new thread for the development of Sofirn's SP70 "BLF Edition".

http://budgetlightforum.com/node/66964

 

I hope all of you agree that this thread is now being separated for the "BLF Edition" might deserve to be discussed in detail elsewhere. Thus, this thread here can remain for any further discussion about the standard SP70. I therefore encourage you to post your ideas and suggestions for the "BLF Edition" in the new thread. I will try to keep track and collate any updates and progress during its development over there.

 

Jason, Dale and anyone else who could help me summarize the most important charecteristics about an improved SP70, please feel free to post it in the new thread.

Thank you very much!

Cheers,

Thomas

Ah damn it.

I know they are using BeCu, but they haven’t told me what type.

They could be using:
1. BeCu C17200 22% IACS.
2. BeCu C17530 38% IACS
3. BeCu C17500 45% IACS

Looking at the current achieved here, it looks like they are using BeCu C17200.

On one hand, that means they are about 55% the conductivity of BeCu C17530 that I use, and the longer spring along with the thinner inner spring means there is much more resistance.

On the other hand, I do support their decision for cell compatibility purposes.
BeCu C17200 has close to the same mechanical properties as steel, but with 3-3,5x the conductivity of that.

That means variously sized 26650s and 21700 can fit in the same light without making it very hard to close the light.

Or they could just be using phosphor bronze. It’s obviously not steel though.

That means the BLF edition can be improved on that point however.

So, BeCu C17500 45% IACS would be best for lowest resistance?

I would include that information into the new SP70 BLF edition thread.

Yes, but the mechanical properties are quite bad.

BeCu C17530 is the best overall.

Alright, thank you BlueSwordM. I will put that into the wishlist of the BLF edition and suggest to follow up in the new thread. Wink

I nitpik, that's what I do, but also to get the info out there as clear as I can, sometimes opinions added. The UI is quite usable as-is, but everyone has their own priorities of "musts" and "nice-to-haves"

But, I really do like this light!! It's amazing what it can do stock! Very happy with it, specially considering the cost.

I haven't followed all the reports on throw #'s, but again, very happy with mine with bypasses and good cells.

Very happy with mine.Especially the large well defined hotspot.Quality,UI and tint all fine (my old eyes prefer cool white).While I will definitely be interested in a BLF edition I hope they don’t turn it into just another large thrower.

The Noctigon Meteor M43 Flashlight had Berylium-Copper springs (45% IACS) that went almost completely flat after a short time of usage. I can’t remember whether the spring metal was to blame or the extreme heat or both. Don’t remember what they did to fix it.

@cncyana, that’s right.

BeCu C17500, while having the best conductivity of all BeCu spring alloys, also has very poor yield strength.

That means plastic deformation, especially with a small top diameter—-bottom diameter ratio, is a huge problem with the Intl Outdoor spring.

Doubt it was heat at all.

The stock M43 driver would never pull enough current to make the springs to hot.

Just for the record, there is no centering ring.

The base of the reflector doesn’t sit on the MCPCB either, instead, it seats on the cut shelf in the head via the belt around the reflector such that the base hovers approx 1-2mm above the MCPCB.

Interesting… I swapped out the MOSFET for an SIR404DP, changed the leads to Turnigy 16ga. With spring bypasses in place (still dual springs) and Samsung 30T’s freshly charged this light makes 10,500 lumens at start and drops down into the mid 8000’s by 30 seconds. In this case, the head IS starting to warm up nicely. Big Smile

Edit: Recharged the 30T’s, looks like it’s pulling 21.3A at start at the tail.
