Arc4x 1-Cell vs 2-Cell

Great chart T_I_N. Looks like it is a winner on a 2x123 configuration.

Thanks. Both tests were performed without any external cooling. I'd expect both lights (especially the 2-cell) to perform even better if held in the hand to absorb some of the heat.

I fail to see any major point of using two cells. Sure you double the run time, but at twice the consumed batteries. The time per battery is close to the same. All that you gain is a longer time between battery changes and then you change twice the number of batteries.

Nonetheless, the graph was interesting and appreciated.

So if the light were run while held in the hand, you would maybe see runtime decline, but time at max brightness go up?


Great job as usual.

RayT, if you are away from batteries for a while, you would definitely want to take the 2 cell with you. Like if your lost in the woods for example.

NO, I'd expect to see a longer time of substained higher output. Don't forget how the Arc4 works. It's tempature regulated in the fact that it starts stepping down upon higher tempatures. Holding the light in the hand, especially with the 2-cell tube, makes for a much larger heat sink with your hand absorbing the heat. That would yield in cooler tube tempatures and cooler LED tempature, allowing the software to not want to step down the brightness due to heat.

I can see several reasons that I won't go into listing, however it's nice that it's possible if needed. The way the 2-cell Arc4 feels in your hand is awesome.

Agreed. For an EDC, I would not want the added size of 2-cells, however if I was consciously going somewhere where I know a light is required (camping, hiking, walk in the woods) the 2x123 is the way to go. It not only gives you the added runtime over 1-cell, but allows for a better grip.

OK, that sounds reasonable. When I go camping I generally take along a couple of extra batteries so run time is not an issue with me. I cannot speak for the holdability as I anxiously await my Arc4x and have yet to fondle an Arc4. I will have to take your word for the "feeling."

It's pretty disappointing that the 2-cell config can still only run for 10 minutes or so at level 1. Is that a thermal cutout, so level 1 comes back after the light cools down?

With 2x123, Level-1 runs at 20-minutes. It would be longer if being held, however I'm not willing to test that.

is your Arc4x brighter than a stock L4??
the LS 5 is suppose to be around the same output, I figured the 4x is the same
thanks

The Arc4x is brighter and more effecient than the standard Arc4+.

Thanks TIN,

belive me or not , but i was thinking 2 days ago to ask for a comparision like that.

When my HDS_2x123 tube arrives in Italy i 'll do a test using my Arc4+ and some 17670 Li-ion.
