they will work for sure, but only if voltage of battery is below 3V or so :wink: try it out and you will see the “red light of danger” :smiling_imp:

Indeed! I didn’t know it’s a battery indicator.
But I noticed that my “HOT” is not in the middle. Perfectionist’s hell. :rage:

:stuck_out_tongue:

did you also notice your aux led lights in the switch aren’t square to the sides of the light?

lol they’re a lot more square than they are in my PL47 but they definitely ain’t centered

Mass is caused largely by that super thick and heavy shelf. Which is worth well under 10% in sustained output. And not because of thickness but because larger head has larger surface. Well, strictly speaking thicker shelf reduces thermal resistance and therefore reduces LED temperature. But that’s well under 1%.

Mass improves turbo time, that’s it.

That’s how they are supposed to work. Outer and Middle rings light up all the time (depending on Anduril setting).

However, the innermost ring is the low voltage indicator. It is only supposed to light up when voltage is low.

my attempt to show the LVD LEDs

Thicker shelf avoid bottleneck to the fins that where reworked to increase the surface of exchange with air by convection. With the final prototype, heat has a better thermal path and larger surface for being evacuated = higher sustainable output. Right ?
It was redesigned, not to improve compacity but thermal management, and there isn’t 36 differents ways to achieve it with passive cooling, isn’t it ?

I was responding to Ektasis that no, it wasn’t designed and redesigned for maximum compacity. If it has this final shape, it is for better thermal management, or I missed something reading this thread since day1.

Anyone else here having trouble getting “Add to Cart” button to work on ff-light.com? I tried in 2 different browsers, but it doesn’t function.

With Brave (chrome modification) works perfectly.

You don’t need it to be 1 cm thick to not be a bottleneck. 5 mm would be overkill already.

Wrong and right. Thermal path has little to do with sustained performance. Larger surface is a biggie. What matters is ability to evacuate heat out of the light. So conduction to user hand, convection from the body and radiation from the body.
Strictly speaking better thermal path makes the led run cooler. And cooler means more efficient. And more efficient means better sustained performance. But that’s purely marginal.

ah wow… that would annoy me like hell :person_facepalming: they really need to make sure stuff like this dont go outside their factory…. come on

Works on Firefox.

Have you check (ALL) check box options?

Including Accessories? IE: None?

Thanks. I’ll have to re-check that. You’d think that any required fields would be highlighted if not selected, rather than simply preventing the “Add to Cart” button from functioning.

pics of the copper is on neals fb page… looks nice

Anyone know the N times default config for Floor and Ceiling Cfg? I have changed it and now the Ceil it’s almost the same to the turbo.

Black it out with a sharpie so it doesn’t stare you in the face all the time.
You can always wipe off the sharpie later …

Default ceiling is 120 (click 31 times after prompt). Max ceiling (= turbo) is 150 (1 click after prompt). Not sure what level default floor is set to, but lowest possible setting is 1 click after prompt.

Thank you, I’ll try it.

What’s the recommended “Temperature limit” setting?
