I don’t think there is any opinion as far as 10A@3v and 5A@6v. It is basic ohms law. We are talking about the same amount of power.
If you look at that diagram
you can see the dark red line which is the 50.2. It is virtually the same output at 5A@6v. And this is an older J4 bin 50.2. Newer versions have better bins with a little higher output.
Also keep in mind that just because a bare led measures 3500 lumen doesn’t mean that you will get the same from a flashlight. You always get less due to losses in the reflector/optic and lens. In the SP33 50.2 I measure about 2200 lumen out the front (OTF). I did not measure current at the emitter, but I think it’s about 2.7A or so. I measure 5.8A on the battery. 2.7A on that chart, plus the losses gives you about 2200 lumen OTF.
With a FET driver you are not regulated to 5A@6v. You might get 8A or so and then you might see 3500 lumen OTF. Of course the wattage is now 40W, a 33% increase and it will generate more heat.
If you used the SST-70 in the SP33 50.2 boost driver version you would get nicer tint and longer throw, even with the stock reflector as it’s barely textured. If that is what you want, it would be a good swap.
BTW, why are we talking about 5A@6v with the SP33 boost driver? I checked my notes and it’s way less than that. Probably about 2.7A@6v.
I like that slogan, too. Originally, I would have favored our initial BLF approach of "Sofirn...turns night into day" or maybe a nice hommage to the book of Genesis by using "Sofirn...let there be light".
However, I wish we could have this phrase of yours just a little bit shorter without losing their intended message. How about these ideas?
"Sofirn...no compromises in quality, service and price"
"Sofirn...no trade-offs in quality, service and price"
"Sofirn...turns innovation into light"
"Sofirn...great lights at affordable prices"
"Sofirn...great lights for everyone's needs"
"Sofirn...great lights for everyone"
They also want to think about a new nice logo for a better corporate design.
I think we all agree that it would look much more appealing with a nice logo instead of their brand name simply laser-engraved in Times New Roman font. ;-)
I fully agree. I heard that from a marketing-psychologic point of view it's always better to express things in the affirmative. I'm no native English speaker either and I want to avoid marketing disasters like some adverstisements of popular brands, e.g. Mitsubishi's "Pajero", Mazda's "LaPuta" or Chevrolet's "Nova" in Spanish-speaking countries... :FACEPALM: :D
If I were Sofirn, I would write a decent briefing of what I want and need, then contact a good advertising agency with professional marketeers, art directors/copywriters and specialists in corporate identity design.
Just a quick ’n rough search on Google and put together just as quick…
1) Which flashlight companies actually have a slogan, and can you recite them?
2) This list is culled from Sofirn’s AX store, not counting “new version” variants that haven’t been formally designated as such. How easily can you discern which line is denoted by each designation, and tell the differences between them? Which is the headlight? Which are the bike lights? Which are the tactical models? The can lights?
What does an S suffix denote? An A suffix? That must be the newer one, right? B must be even newer. But wasn’t there a the SC31A? What about version 2 or 3? Would a SC31B successor be named the SC31C, or SC31B v2.0? SC32? Or something else entirely?
Some of it makes logical sense, but a lot of it doesn’t. Nothing wrong with a slogan printed on a box that will end up in the trash, or in drawer.
But IMO, a serious effort to improve the marketing should include a rationalization of the product models, and how they’ve named. Heaven help those who aren’t flashlight enthusiasts, stumble upon the AX store, and try to make sense of it. It would be fun to quiz Sofirn employees to correctly identity each model by name, and see how many can achieve a perfect score.
But yes. Any list without an Oxford comma is just plain wrong.
