If I ever wanted to mod mine that’s the best way to deal with it.
hi you can heat the head to about 100 。C.

I did reflow new leds by just heating up the whole head with the ledboard in place, but I did not check if the glue gets soft enough to remove above 100degC. I may try that next time
that is no problem
E2L now have high CRI led selections, Nichia 219C, Ra=9050
it has been more than 1 year that E2L was firstly sell…
And it is still the best host for triple led
Jaxman, what do you think about new version of E2L - with 20700/21700 (18650 with adapter) battery, 20x7mm dc-dc driver ?
That would be awesome.
I would buy one too

Yes I’m ready to send my money! :+1:
Absolutely, count me in (as if I don’t already have more than enough lights…).
The current E2L has the optics partially eclipsed around the edges. With a slightly bigger diameter, the optics would be a perfect fit.
oh,it seems that much of BLF guys do not like our power setting on this light. you need very hot driver such as BLF directly fet+pwm 7135 driver?
Our E2L is powered by a 2A current, then I have feel it is very hot after 5 minutes working on high mode…
with a FET mode,4A or much big power,I cant think about it…
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….
Good wishes
Yes, I do not want a FET driver in such a small light. It would get too hot, and it is dangerous for not us users.
Boosting the current to 2.8A, and adding a 1lm moonlight mode would make your light even better.
Or maybe just add a 1lm moonlight mode if it is possible and perhaps use new 4000k Samsung LH351Ds, that are more efficient than Nichia 219C 4000k.

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 would buy a 21700 host, that would be great. Just make sure the head will fit a 20mm triple or quad board without sanding…
