If someone makes a light and recommends AAs and 14500s and fails to say — don’t use Eneloops because the light will malfunction and who knows what will happen — then that is a problem.

Hum, they don’t have to specify Eneloops, as those are only one type of Ni-MH branded cells among N others.

Just to give another example: I never used my SF14 with AA cells because the first batch of that light couldn’t even take a Ni-MH cell, only alkalines and 14500s!
I wrote this here by that time, and asked Sofirn to correct the tube so that it could take Ni-MH cells:

Quote:
In terms if internal diameter, the tubes of the SF14 flashlights are from the first batch, that are narrower. All Ni-MH cells I have don’t fit. Only Alkalines and 14500 (unprotected) batteries fit well.
Quote:
- BATTERY TUBES : it would be a plus to be able to reverse the pocket clips, just by changing the polarity of the tubes. Also, to revise the inner diameter of the SF14 tubes to fit Ni-MH AA cells and protected Li-Ion batteries.

They could, however, specify that using Ni-MH may imply some issues.

If you check the Jaxman E3 thread, an AA flashlight, you’ll see that jaxman mentions that the use of 14500 cells is not the most appropriated as the driver is mostly done to use with AA alkaline or Ni-MH cells. In this case is due to the heat produced and the outputs being similar between Ni-MH and 14500s.

Please don’t get me wrong as I am not trying to prove a point here, nor to defend Sofirn as I have nothing to do with them. I’m only trying to check that just because it doesn’t say it (Ni-MH cells) can’t be used, it also doesn’t say it (Ni-MH cells) can be used.

However, if those issues persist, I guess you can contact Sofirn, through the forum member or through their AliExpress store so that they can help you solving this. If it has a solution, of course!! Beer

NiMH has the lowest voltage of the major types, and that’s no-load. The controller might have a hard time starting up if it’s already at a low voltage, then tries dumping lots of current to make its supply voltage even lower. At least an alkie can still register at 1.5V-ish at no load.

At lower loads, maybe the voltage holds up more. Then as things heat up and LED current decreases and/or resistance somewhere increases, the sag isn’t that bad and it steadies out.

I remember a digital watch (old-timey red LED digits) would go mental when the battery would start getting low, but noticed it was especially when more segments were lit. Ie, it might work fine at 1:17 but go mental at 12:53.

So… no idea. Big Smile

Yep your right, I should have said NiMH… not just Eneloops. Thumbs Up I edited & made the change. Wink

Thanks for pointing that out. Smile

I noticed that mate Wink Thanks!!

I don’t have Eneloops nor the correspondent IKEA batteries, I only have some Panasonic Evolta Ni-MH and other “Lidl supermarket” Ni-MH batteries. I do know that Eneloops perform better, but if they are not performing well on the SF14 and other Ni-MH also don’t do the job well done, the focus here must not be the Eneloops, but the Ni-MH rechargeable batteries.

And it must be addressed to the manufacturer.

I do remember that the runtimes pointed out for the SF14 and SP10A/B was only for 14500s and AAs, and for Ni-MH they should be different but they were never mentioned. So, maybe something is missing here.

I never noticed any flickering on my SF14 or SP10A/B when running with Eneloop AA but I haven’t used them since my initial play with them because I use either my Zebralight SC5W II or Reylights when I use AA lights. The Sofirn AA lights are just not bright enough.

I have three of the Jaxman E3 with a fourth on the way.

I decided to try the Sofirn SF14 because of 1) the price 2) it is slightly thinner than the Jaxman, although longer 3) and because of Jaxman’s warning about using 14500s.

The AA size lights make for good pocket EDCing. They also make good gifts. That’s why I need them to use both 14500s and Eneloops. Most non-flashaholics won’t use lithium ions. So I include Eneloops with the flashlight, along with a charger.

The Jaxman E3 produces enough light on Eneloops for me to take the dogs out in the yard to pee. But not enough light to walk them in the park. That’s why I like a light that uses both Eneloops and 14500s.

Someone mentioned contacting the maker……that is where I started…. But the only option Amazon gave me was a return.

Since Sofirn sent me a model I would consider defective AFTER they introduced their new version, I would be suspicious of what they might send me next if I bought a second SF14.

My suggestion to Sofirn — take all the version I SF14s off the market and remove the link from Amazon and elsewhere. Start a new link and label it Version II or new and improved or both.

And then specify whether or not it works with Eneloops.

Thanks for posting. 4A is going to bring significant voltage sag, and with an NiMH, there isn’t a lot of voltage to start with.

Nope, not really, though they can source it for longer:

This doesn’t necessarily explain why the flickering seems to come and go though, unless the v1 lights also have active thermal regulation, beyond just stepping down on a timer, and end up reducing their current draw to manage temperature.

Thanks for taking the time to check this. I learned something.

The delayed onset is consistent with the notion of heat being the problem. In one video I noticed that turning the flashlight off and then on, does not make the problem go away, but turning it off, and waiting a bit, does, albeit, only temporarily. The problem with NiMH might be that battery IR is too low, current is too high, and heat results.

I don’t know much about driver electronics. Is this a buck/boost driver that bucks for Li-ion (above a certain voltage), and then boosts for lower voltages, including Li-ion, alkaline and NiHM? Does it make sense that the boost section could be prone to overheating only on NiMH? Presumably this would be because of low IR and higher currents. Now that I’ve written it out, the idea does not sound very convincing.

Anyway, as others have already said, it looks like either the flashlight, the driver, or both were not designed for NiMH.

4A is no problem with Eneloops. Running voltage will be over 1.1v. Alkalines will die immediately under that current, and even at 2A will drop below 1.0v very quickly.

The new SF14 is out, and has some differences in aspect (smaller, larger, seems to have removable bezel, has “V2.0” marked on the head, …).
Let’s see if it does work better than the previous version in those aspects mentioned here!

EDIT: From the link:

Quote:
Working Voltage: 0.9-4.2 Volt

Battery support: single AA Alkaline, or AA Nimh, or single 14500 battery (Powered by 14500 battery to get the max brightness 550 lumen )

EDIT 2: to specify if it works with Eneloops, they have to specify if they work with the N other brands of Ni-MH batteries once not all the people have the money to buy or the access to Eneloops!!! :ARROW-RIGHT:

FWIW, last night I tried to duplicate the "flickering in high mode using a Ni-MH battery" anomaly in my SF14 and couldn't do it. Took an Eneloop down to 0.9 v and the flashlight seemed to remain stable all the way. But, as confirmed to me by a Sofirn rep via PM this morning, part of the SF14V2 upgrade is to address this anomaly.

Some added evidence that supports the hypothesis that thermal throttling may be responsible for the flickering ending once it starts. Shortly after switching on and going up to turbo/high, my IR thermometer reads a temp of ~70°c from the emitter. The temp drops somewhat once the flickering starts, which isn't surprising. However, when the flickering abates a minute or so later, the emitter temp stablizes at ~65°c. This is not a result of the driver dropping down a full level, it's still in turbo/high. If I do a quick press, the light wraps around to low mode. I may try doubling up the tail spring later tonight.

 

The addition of a  Direct Thermal Pat (DTP) Metal Core Printed Circuit Board (MCPCB) <generic illustration below>, and a throttling back of the max lumen output from 600 to 550 lumens should mitigate thermal build-up problems in the SF14V2. According the Sofirn rep I PM'd yesterday, the new MCPCB in the SF14V2 is copper and not aluminum.

But this doesn't help existing SF14 owners that have the flickering problem.

You can’t really blame the manufacturer. The light works well with a duracell AA, which is that battery that they intend to be used. Not everyone will put an eneloop in there. Even fewer people would put a 14500 Li-ion in it.

Sorry, that’s just wrong.

The above screen shot is from a browser I had left open. One may just as well pay $16.09 (with the coupon code) on Amazon and get the flashlight with battery and charger.

I don’t know about the price fluctuation, but since it is a new product, they may be still adjusting it.
I remember that in the beginning the original SF14 costed a bit more than what it costs now. So maybe they are still adjusting values. Also, Coin values tends to make some (little) impact!

If you check the AE App, you’ll find a 0.88€ coupon for buying more than 13.03€, so it will bring it down almost 1 dollar!

At this writing, the listing on Amazon says the “upgraded” SF14 is expected in stock on Aug. 8, 2018.

The price for the upgraded version with battery and charging slot is $22.99.

The price for the SF14 alone is $14.99 — same as the old model.

But perhaps it is the old model when you purchase light alone, since it is rated at 6t00 lumens, same as the old. Whiled the updated version is rated at 550 lumens.

I do not see any coupon on the Amazon site, as of this writing.

Reducing the rating by 50 lumens and calling it upgraded makes me wonder what’s going on.

After this controversy, Sofirn should stop selling the original SF14. I hope this is simply an oversight on their part in updating the listing for the light alone.

Still no rating listed for Eneloops, or NiMH for those who may be unaware that the chemistry is the same.

The code I used to get the 30% off SF14V2/Battery/Charger deal (i.e.GCRBWXTC) no longer seems to work. Sorry,

The flashlight alone on this page is the old SF14.

You can’t really blame the manufacturer. The light works well with a duracell AA, which is that battery that they intend to be used. Not everyone will put an eneloop in there. Even fewer people would put a 14500 Li-ion in it.

Sorry, that’s just wrong.

Unfortunately, it’s probably correct. The vast majority of people have never used rechargeable batteries of any kind in their flashlights.

I’m not sure what the demographics of Sofirn buyers are, but they’re probably not all flashaholics.

That said, there’s no excuse for not designing devices to accept NiMH batteries. For at least half the capacity, a NiMH cell will be running with a voltage higher than an alkaline. If a device won’t work with NiMH, then it will be giving up half the capacity of an alkaline too. Running your devices only with full alkalines is even more expensive.

Interesting. Can a flashlight manufacturer stay in business catering to the needs of enthusiasts? How many units must they sell before they break even? I’m using a little 14500 Olight as my EDC. My little Olight costs less than the Chinese junk garbage they’re selling on amazon. I read reviews for lights I’m interested in. Garbage, plastic lens AA zoomie gets 16,000 decent reviews. Thrunite. Olight, Nitecore, Thorfire lights that are decent, costing less than t the Chinese-Garbage lights, but the good lights have the smallest fraction reviews.

Based on reviews, a junky garbage plastic lens TACTICAL flashlight is the one you really want.

I understand that the quality and quantity of reviews can be manipulated by unethical vendors, but 16,000 mostly positive reviews?

As an example, my most recent light is the Catapult V6. Who but folks like us would buy a light like this?

I’m just saying is all…

The 30% discount code (GCRBWXTC) is listed under the “Special offers and product promotions” section of the Amazon listing, not near the price like coupons are clipped on Amazon listings.

Better yet, PM Sofirn here and see if there are any 50% codes remaining, as noted in the other thread.

Either way (if the AMZ code is not working), I’d try a PM, and they should be able to take care of things.

The promotional code works and brings the new version of the SF14 with battery and charging slot to just under the price of the old model with its defects.

I do not see any way to order the new version of the SF14, with or without the accessories that I wouldn’t need.

Of course, who knows if this listing is correct. I got an SF14 just this week and it was the old model.

You can, through AliExpress Store of Sofirn Official Store. It has been said above here!

The new version of SF14 was released this week! See here: http://budgetlightforum.com/node/61660 .
If the order was done some time ago, you wouldn’t get the new version, just the old version…

I’m not sure what you mean, because your statements contradict. One says the code works on the new version, and then the next says it’s not possible to order the new version.

To be clear, the Sofrn rep here provided an Amazon link to the new 2.0 version of the SF14 in the other thread, in announcing their availability earlier this week.

There is a 30% off code on the page, or a 50% code if you PM them here and ask for it.

For the time being, both the new v2.0 of the SF14 and SP32A are only being offered in kit form from Amazon. And in the case of the SP32A, only the black color. The cheaper SF14 listing with the bare light is for the old version. In addition to the price and configuration. the difference between the two listings can be discerned by the lumen ratings, as well as the picture of the light.

Subsequently, the bare SF14 v2.0 must be ordered from their AX store, as well as the pale gold and silver colors for the SP32A v2.0.

Even if one doesn’t require the battery/charger, the Amazon SF14 option is clearly preferable, as either the 30% code can be used to bring the kit to the same price as the bare light on AX, or the 50% code to make it an even sweeter deal. And it will arrive within a few days for Prime members once it becomes available, versus weeks from AX.

Selecting and buying from these hobbyist-oriented Chinese brands requires some caution and some attention to detail, because their marketing and methods of distribution can be confusing, but that’s nothing new, esp. for BLF members.

Thanks for posting. 4A is going to bring significant voltage sag, and with an NiMH, there isn’t a lot of voltage to start with.

4A is no problem with Eneloops. Running voltage will be over 1.1v. Alkalines will die immediately under that current, and even at 2A will drop below 1.0v very quickly.

Sure, but 4A is enough that the voltage drop due to resistance in the spring, switch, etc needs to be considered.

Yes, but that would be an issue with poor design.

For example, the Zebralight SC5 has no issue putting out over 500 lumens and running an Eneloop over 5 amps. The Eneloop handles it just fine. But, you’re right, the flashlight probably has little other resistance to get in the way.

I don’t think there are many manufacturers that can afford to cater only to flashaholics. Even Zebralights, which are moderately expensive even by flashaholic standards, must have to sell far more lights to “regular guys” than they do to flashaholics. So there must be a market for selling $100 flashlights to lots of people. Granted, they’re probably outdoor enthusiasts and not couch potatoes, but they must outnumbers flashaholics by a large amount.

The only brand I can think of that likely caters to flashaholics (and maybe some ridiculously overpriced government contracts) is HDS. But with them you’re paying astronomical prices for a relatively unimpressive light (though very tough from what I hear). They probably have to charge so much because the volume is so low.
