a new EDC light of 2017- JAXMAN E2L

I read some Convoy have this option (and some Jaxman had too) :

Group 1: 5-Mode (high—mid—low—fast strobe—SOS strobe)
Group 2: 3-Mode (high—mid—low)
users can switch Group 1 into Group 2 in low mode.vice versa.

Do the E2L have the same option ? (low mode doesn’t blink once like on tne Convoy)

That I’m unsure as I run protected cells and the circuit cuts out before lvp does on the light.

The lower the kelvin LED, the lesser the lumens. To make a NW and WW led like the Nichia, requires darker or additional phosphor. Because of this thicker blanket/darker phosphor covering the blue LED it lowers the lumens vs a CW LED with less/lighter colored phosphor.

You mean “blink” for low voltage protection ?
No, on the Convoy with 3-5 driver, what I understand is that at startup in Low mode, after a few seconds, light blinks once (and at this moment you can begin group switch procedure) Maybe I’m wrong…

I don’t know what the E2L’s LVP protection warning pattern is. My batteries have a protection circuit on board and shuts off power before the light’s built in warning has a chance to activate.

Ok, but I’m not speaking about the LVP blinking :wink:
On the Convoy, light blinks one time just seconds after Low mode is selected, and at this very moment you can switch from group 1 to group 2.
Example on video : - YouTube

It was also possible on the Jaxman X1 (but I don’t know how) and I’m asking if it’s the same thing on the E2L… or not :wink:

The E2L has only Low, Med, High. There isn’t a group mode. So if it does flash for anything it’s certainly not for changing group modes.

I’m having a problem trying to replace the stock driver of my E2L. The TIR lens does not move at all, it’s stuck firmly to whatever underneath it. I’m afraid I’m gonna break its legs before I can remove it. Any suggestion?

Some temperature measurements

some anomalies becouse body measurment wire break loose

The TIR legs are not glued but fit very tight in the ledboard holes. It requires some bravery and risk but if you pry with a very small flat screwdriver near the legs the TIR should come off.

And then there’s the next problem of the ledwires glued in. :smiling_imp:

My advice: leave the front side of the head alone and just get the driver out, the ledwires are long enough to tilt the driver and unsolder the wires there.

Nice info matik! :slight_smile:

Thanks matik42, for the measurement. I remembered mine was uncomfortably hot after 10+ min. at high.

Thanks djozz, I think that is a better way to do it. Should have asked before removing the bezel, that’s already too tough for me. :weary:

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.

Rgs

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 :slight_smile:

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…
