FREEME ✌ LUMINTOP FW4X XP-L HI 219C 3150lm Adjustable Color 18650 Flashlight Group Buy >>> $44.95

- Does this mean the driver is using a attiny85 chip and can be flashed to Anduril?

  • Will there be Ti and Cu versions made?

I didn’t notice initially that it uses a frosted lens, so yeah in this case there shouldn’t be any significant issues with the beam.

But it’s click and hold to turn off. Not for me. I only have one light that does the same and it is always frustrating to remember that.

It really would’ve been nice if the color control was made as a menu shunt off of the main Anduril UI menu. Anduril is so rich… and sacrificing that for temperature control is too much of a disappointment. If it doesn’t sell well, maybe Lumintop will reconsider this for a replacement.

Unfortunately, that is probably one of the reason why it does not appeal to the general public.

It is a good to have feature but it is never a "must have" function when i shop for my flashlight.

Well, with primary Anduril 2, you get a light in Simple UI mode and the user can simply stay in Simple. It’s actually quite nice. But it would be nice to then add the 2 separate emitter cluster controls as another menu item. And also make that available in Advanced. So if a light is equipped with 3 emitters, it’ll be 2 groups where one has emitters #1 & #2, and second has just emitter #3. And with 4 emitters, two sets of 2 emitters. Doesn’t matter what tint. But if a light is designed with 2 sets of different temperature emitters, they’d be mounted in the predefined groups for independent control.

Please answer

FW4X's driver looks different to me.

So it would probably need its own version of Anduril, if it can run it. We would need to see the other side of the driver too, to see if it has an ATTiny85 chip or not. Would you be able to show that?

Also, do you know if there are plans for Ti / Cu?

Would be all over this if high cri through the range. 2700k/ 5000k lh351d or 2000k/ 5000k e21a as examples.

Interested freeme. Thanks

See first post link.

Long press for off. Fail.

Yeah, I take back my earlier comment. Leds can be swapped but this ui and heavy thermal step-down are big issues. A shame, as lumintop finally got 900lm sustained in the fw3x not long ago.

Which light is that?

I thought the FW3A could only do around 300 lumen sustained.

It can do a lot more than that--I'm thinking at least 900 lumens sustained.

900 sustained in an ice bath maybe. Take from the review below “Without any cooling or heatsinking (air, hand) the maximum sustained output is below 300 lumens if you want to keep the surface temperature below 50°C.”

That has not been my experience with the FW3A.

The FW3A can easily sustain 900 lumens without any cooling.

300lm is rather low even for warm climate countries.

Is that just your impression or have you tested it in an integrating sphere?

My recollection from reading reviews of people who did test their lights for runtime and output was that the FW3A sustains around 300 lumens (and that’s the cool white XPL HI version) and the Emisar D4 (also XPL HI version) only sustains around 500 lumens.

Sustaining high output is actually quite difficult for small single cell lights. Even a Zebralight SC700, which uses a 21700 cell and is much larger than an FW3A with vastly superior heatsinking and an XHP 70.2 led barely manages to sustain 1000 lumens.

I own several FW3As and I think the estimate of around 300 lumens sustained is about right. These are tiny pocket rockets with no real heatsinking. It’s not surprising they dim fast. My Zebralight SC64w and SC64w HI stabilize at a much higher output than an FW3A… not suprising considering how good Zebralight’s heatsinking is (unibody construction with lots of heat sink fins).
