Me personally, 2A or even 3A is nice and bright for a tubelight with single emitter. A triple should be a little more efficient per LED, even though they sum together to dissipate the same power.
A tubelight can only dissipate so much power, not like a bigger light with lots of angry fins sticking out. I wouldn’t worry about cranking up the current.
Although I have reviewed dozens of lights, your E2L remains one of my favorites. I have paired it with a BLF 17DDL driver and that’s probably another reason why I like it.
Even though the flashlight can’t sustain the full FET current for long , it’s always pleasant to know that you have this kind of power available to you.
@jaxman Do consider making a stock triple with a FET driver…!
20700 is not a battery that easy to get. and the size will be much larger than present.
And I am worry about the over-hot hurt to the user and the battery risk is increase if the power is big enough.
in fact I have made some FET driver verison to one of our OEM customers.
I do not dare to write JAXMAN to a FET driver flashlight…I am worry about…
so I decide to sell host to you… you can diy it your self….
Agreed. To feed a triple/quad with FET, currents can be uncontrollably high, which is not desirable for this host (with the current head size) - and also it would limit emitter selection regarding current / Vf characteristics.
Many new drivers have thermal management, if not then at minimum there is a short burst timeout to keep things from overheating. Makes for a very nice light…
I think a larger version of E2L would be welcomed. I see it like this:
E2XL - 21700, quad carclo, 20mm driver
E2XXL - 26650, quad or triple noctigon (xp32 or new 4xp), 22mm driver
And sizes will be increased very slightly, for few mm.
driver ?
I wrote about host for new E2L, currently I use 2 E2L with LD-4 (linear) drivers .
If new host will have more space for driver, for example 20x7mm, we can install 20mm drivers, and very efficient DC-DC drivers too.
Currently 20700 and 21700 produced by 1st class manufacturers, such as Sanyo / Panasonic, Samsung, etc.
But 26650 produced only by 2nd-3rd class manufacturers .
Banggood had made a copy of JAXMAN Z1 flashlight. The company who helped Banggood to copy Z1 is MANKER. And MANKER is only a dealer, MANKER found a fatory, to copy Z1 for Banggood. :rage:
So we cancelled all corporation with Banggood. They are a rubbish company, they even called the copy as a JAXMAN flashlight.
Banggdood have asked us to sell flashlights to them for a few times, but we refused. We would not like to make business with a thief. We dislike thire money, either. Ever, never.
Yes, Banggood was our distributor at first. They sold our flashlights included Z1. When they buy the copy “Z1” from MANKER, they still sold copy as JAXMAN’s brand on their website.
And even worse, MANKER known JAXMAN products, and they made the copy at last. So, I think MANKER also is a rubbish company. They take money as the first important thing.
I think I’m going to side with Jaxman on this. I have not had a single problem with Jaxman products, and I’ve had a few issues with Manker ones. I’ll pick Jaxman any day. The Jaxman Z1, and E2L lights are fantastic!
