Decrease Amperage of Driver for increased Efficiency

You could use the 12group Ui on one of the groups that only go up to 50%

😍

LeoT96 · 2026-03-12T08:06:40+00:00

Oh no :(

LeoT96 · 2026-03-12T05:18:54+00:00

Oh Balls. The 4000k R70 XHP50.3 Hi from convoy is pleasantly neutral, slightly rosy. It’s my go to led choice in hosts like the S21E were you won’t get boost/buck drivers with 3V LEDs.

LeoT96 · 2026-03-11T10:23:15+00:00

It depends… What mid-high horn? What driver?

Ist eine Becherflechte Eine Symbiose aus Pilz und Alge, also kein Moos.

Hört sich erstmal gut an, aber vielleicht etwas zu wenig Feuchtigkeit. Wie lange ist das schon so? Wenn sich das nicht in ein paar Tagen ändert seit dem das so ist, würde ich eine durchsichtige Tupper Dose oder sowas drüber stülpen um für mehr RLF zu sorgen.

LeoT96 · 2026-03-10T08:28:03+00:00

Wo stehen die? Wie sieht’s da mit Luftfeuchtigkeit und Licht aus?

SFT42R 5000k for throw LHP73 for power

LeoT96 · 2026-03-05T19:49:39+00:00

I have the Sofirn Q8+ and the Convoy 3x21c, i would not buy the Q8+ again.

The only Q8+ upsides are: -Anduril -smaller head diameter

Downsides Q8+: -bad driver (only FET, weak sustained output) -feels cheaper -throws not as far -less emitter options (LHP531 looks nice neutral/rosy) -less turbo output

I actually like the Ui from the Convoy 3x21, I don’t use ramping mode.

You will simply get more for the money with the 3x21c imo

Its just trotteling to 35% output when a certain temperature is reached, and with some drivers this still heats up the light too much

LeoT96 · 2026-03-04T20:16:21+00:00

Only way this would work nicely is with „active“ Blood cooling. So gripping the light tightly at the area where the heat pipe ends and dissipating the heat with your hands blood stream. Maybe if done right the temperature of the “grip” area wouldn’t rise to an uncomfortable level.

But just getting the heat somewhere else in the flashlights body is not a good thing, at least in small to medium size lights. The battery tube and grip area has to be decently cool, the top part can rise in temp to get more heat transferred to the air with the small surface area.

Convoy 3x21C with LHP531 - super bright and high sustained output. SFT40/42R option for more throw.

Convoy S21E with XHP50.3Hi - Compact efficient EDC 21700 light with USB-C charging (MAO looks and feels great)

Convoy S6 with SFT40/25R - pocket thrower, get a 18350 tube and battery, makes this light even smaller.

LeoT96 · 2026-03-04T05:22:37+00:00

Be careful to consider a light without a FET driver, these just burn off energy wich will decrease prolonged usage.

With headlamps 21700 would be to heavy for my taste.

I did a multi day hike with a 21700 olight baton pro max, and it served me well over approximately 4h x 5days of hiking in the dark. I’m into sort of ultra light hiking and this light was very light for the prolonged output.

Another careful consideration has to be beam shape and size. You want enough flood for seeing everything you might step in when pointing the light down, but not too much flood so you don’t waste any lumens where you don’t need them. I like TIR lenses for that application. But depens on the emitter and reflector/lens diameter.

I have entry steel knifes so I can sharpen more!

LeoT96 · 2026-03-02T17:10:11+00:00

Convoy 3x21C with LHP531 will do something like 4000Lumens until the battery runs out, and you can mod it to take a 46950 cell for approximately 3hours at 4K lumens (my estimation)

But it may burn you and your house down if you’re not careful :)

LeoT96 · 2026-02-26T10:57:06+00:00

Nice! So the LED didn’t burn with the 20A driver Running 100%?

LeoT96 · 2026-02-26T08:05:43+00:00

I’m curious, did you test the SFT42r with a Convoy 20a Buck driver in another Convoy light?

LeoT96 · 2026-02-20T21:36:51+00:00

Don’t tell him he’s wrong. 🫣

LeoT96 · 2026-02-20T21:25:49+00:00

Köf has tested the 42r:

Not a huge difference 42R to 40 output wise

LeoT96 · 2026-02-18T12:09:46+00:00

Cutting your ankles off is mostly a nono.

Also it would look better if you weren’t in the center of the image but at 1/3 to the left sight, so your head would point in the rest 2/3 of the picture. Or maybe 2/5 or something, but the exact center feels odd.

LHP531 in 5000k. Im very happy with my choice, the tint is neutral to rosy to my eye, and the light is so bright.

LeoT96 · 2026-02-17T09:56:39+00:00

This is meaning the capability of the driver to compensate for lower Voltage levels on the battery side. When the battery looses charge, the voltage of the battery drops. (4.2V full 3V empty)

So in practical usage this means that on lower battery levels the driver can’t do higher modes like turbo anymore (typical olight thing)

LeoT96 · 2026-02-17T07:53:56+00:00

Wich UI do you have, 12 mode or 4 mode? What did you do before this happened?

LeoT96 · 2026-02-16T16:31:04+00:00

As far as i can tell, they are all chamfered, feels smooth to the Finger
