The new Jaxman E3 flashlight comes in the new year

Looks very nice Jaxman! I like it! Will have to add this one to my growing collection of well made Jaxman lights.

For me, starting with the lowest mode and stepping up to the highest is a requirement due to my poor memory. I tend to blind myself if they come on in high. :blush:

The High CRI Nichia 219C is also an appealing emitter choice to me, hope that’s available when it’s time to order.

Already having the UV tube light (U1) and the triple (E2L), along with the M8 and Z1 and the X1 as well as the M2, this small light will have it’s own distinct place in my line-up. Thank you for thinking of this. I don’t normally use NiMH in these small lights but in this case I might have to make an exception and keep it low for the glow. :wink: Who knows though, I could get some crazy idea to shove 2 14250’s in the tube with an XHP-50.2…. maybe hosts really are needed? :smiley:

Edit: Couldn’t resist, just ordered one with the Nichia 5700K 219B. I know, I know…. :wink:

This is a “good”thing.

In very low output/current levels, the power draw of the circuitry adds significant to what just the led draws. example, the BLF-A6 driver in lowest moon mode may have 2mA through the led but the MCU/voltage divider or whatever, adds another 2.5mA (these are numbers that I think I remember). And the BLF-A6 driver is pretty good at this. I know that led4power pays extra attention to the power draw of the circuitry in his drivers to maximise runtime in moon mode, it is a bit lower even than the BLF-A6. This may be done by designing the hardware right, but it certainly can also be achieved by software tweaking, I know that TomE has done a lot for the Q8 driver to keep the MCU power draw as low as possible in lowest setting (something with putting the MCU to sleep). But other drivers may be pretty wasteful which reduces the runtime in moon mode drastically.
If the driver is a boost driver, the current that the circuitry uses (and does not go through the led) may be a bit higher because of boost losses. Mind that the 8mA that Jaxman measures is at 1.2V, so after boosting there is just maybe 2.5mA leftover to divide between circuitry and led. So if the led lights up at all, the power draw of the circuitry is lower than that.

OHHH, ok, first I got it all “wrong”! Now I understand the “boring” part, cause it will draw slowly on the lowest level!
Thank you so much djozz for taking the time to write and explain it :wink:

Hum, I will definitely get one of these :slight_smile:
Thanks again :slight_smile:

Hi Jaxman,

Your Aliexpress page mentions “the med mode is done by PWM”. Do you know how fast it is? Visible? Audible?

Thanks.

Jaxman,

I'm looking for a single AA capable pocket EDC.

Will I receive the new 3-mode UI if I order now?

Same question.
When new 3-mode glue-free version will be available ?

Guys, have you checked ali page of E3? There is already new model available for purchase.

I have. There's conflicting info.

The site says they now have the 3 mode version and can make the 2 mode version available for the asking. :wink:

I’m interested in the Nichia 4000K but I’d like to know the lumen output specs, in the Aliexpress generic area of description shows: Lumen: 160

I’m hoping that’s not the max output with a 14500 cell.

I have the E2L nichia triple, the listing for that shows the lumen output for all 3 mode levels. Jaxman, please add that information for this one or post it here.

In the picture on ali there is: 1, 60, 350 lumens.

@jaxman, could you please make the listing on aliexpress clearer? it would benefit us all, including your sales, I imagine :smiley:

I see where some clarification might benefit new-comers to the flashlight hobby, but for me, I know it’s made by Jaxman and that’s all I need to know… it’s gonna be good by default. :wink:

I learned from Jaxman that PWM is 500Hz for medium mode, which is way too low for me. Pity that this alone prevents me from buying one.

I hear that kind of thing a lot, how the PWM is too low or too noisy or whatever, but in the hundreds of lights I’ve had in hand over the past few years I’ve personally never found PWM to be an issue. Not once. My son has excellent hearing and he’s heard a light whine, says it sounds like some small bugs, but I couldn’t hear it unless I held it close to my ear and quite frankly, I use a light at night so I can see to do something, never have had one in my ear giving me fits. Everyone has different perceptions of what works for them, of course, just saying that for me it’s never been an issue.

If I had one that was a problem, I’d fix it… of course. Simple enough to do especially when it’s known the driver is a standard 17mm diameter.

For example, as nice as the M4 is in build it kind of bugged me that it was 2x AA in the power supply. So I built a Zener modified FET driver and put an XHP-50.2 in it. Now it uses 2 14500 cells and makes 3000 lumens, it’s really a nice light! :smiley: Richard sells these drivers, simple enough to make the swap if one simply wants to. Don’t solder? Neither did I a few years ago. Even an ornery old dog like me can learn new tricks, and here I am with what… 500 or so modded lights behind me? Simple enough…

I find it annoying when PWM has a frequency low enough that bugs look strobed, same with quick hand movements. I have some like this, and I hope it’s not the case with the E3 (I don’t know what is the frequency on the infringing flashlights I have)

As for drivers, while MTN drivers are cool and I have a fet+1 on my S2+, I find myself looking for these aa/14500 flashlights exactly because of their dual chemistry possibilities, and these drivers are a lot less common. To the point I wished Sofirn would sell their SF14 driver separately.

Since Sofirn has been very forthcoming to BLF thusfar ( :+1: ), you could try asking if they will sell drivers separately.

Thanks, it’s kind of hidden, (from my old eyes anyhow :person_facepalming: )

Do we know what battery type those lumen specs are for?

I don’t see mention of the actual cell tested but any cell should make the specs, they say 1 hour High runtime on the Li-ion and that would mean a 700mAh cell would be pulling 700mA, virtually any cell out there can do that, and the 350 lumens supports that current pull. As long as a button top is used it should be fine. Protected cell might give length issue, don’t know. Not necessary at these power levels of course. :wink:

OK thanks I was wondering if the 350lm was with AA primary, but thinking now that probably wouldn’t be possible :person_facepalming:
Just figured this would have better output since most newer 14500 lights are 500-800lm.

Also I assume the 350lm rating is for XPG2, so the Nichia may be even less.
