A 3 volt driver, like in the Q8, would need to handle 256 amps. That’s not gonna happen. If you ran it at 12v then you’d be at 64 amps. It would not surprise me if the next big mega light used 12 cells and ran them all in series to get the voltage up and the amperage down.
They would probably use multiple drivers built on a single pcb or even a stacked pcb. One mcu could control it, but you’d need multiple fets or coils, etc… Similar to how the MF01 used 3 or 4 drivers combined.
One important thing is to keep the amps down so you don’t fry the electrical traces on the pcb. They can only be built so thick.
- Please kept me informed about this MF03 (7*XHP-70.2 + 1* XHP-35 Hi).
- This is the best idea, combining flood with throw.
- Any chances to make the head diameter bigger, say, 120mm (reflector 110mm), like BLF GT, better then Thrunite TN-40 and 42, better then Acebeam X65 ?
- What is the reflector diameter of the XHP-35 Hi, and each of the XHP-70.2 ?
- How long can the light stay in The TURBO mode ? Only few minutes like others, or any breaktrhough in the heat dissipation tech that it can stay in turbo mode for at least, 40 minutes or so ? Can the HIGH mode be 70% from the TURBO mode ? Can the step be 100% (40 minutes), 70% (100 minutes), 50%, etc ? (Olight X9 never exist, using small fan alone might not be a good idea, but a combination of water-cooled pipe and small side fan like Acer laptop might be a breakthrough).
- Hopefully it can make over 27000 lm and over 1700m throw.
Can the flashlight be flexible, giving choices to users of using 8 x 18650 or 12 x 18650?
Did you really think a bargain light company like Mateminco would come out with such an advanced design?
To have active cooling in a flashlight, the company would have to open an entire new division of the company just to focus on that.
Small companies that make bargain lights just can’t afford to do that. Maybe bigger companies like Olight can do it eventually and without too much expense. All that new research and development costs money, though.
So when we do finally see an active cooled flashlight make it to production (and not just slapped on haphazardly light the Ra light) I’m sure it will be expensive. Like when the very first curved TV came out or the first 4k tv came out. This new technology carries a price premium. Over time though other companies can study and copy their competitors and come out with their own active cooling system. Eventually you will see the prices come down and more lights will use it.
Active cooling is like bleeding edge technology. Olight tried and failed at it with their X9 Marauder. I think they are going to try again with a new light coming out soon. I forget the name of it.
I think it took Simon almost a year to figure out how to get the finish in the pics I posted. His normal “clear” lights like the C8, L6 and S2+ are sandblasted and don’t look as nice.
Maybe you could ask Mateminco if they can do less cutting on the light around the head in particular. The big slices on the head make it look pretty ugly.
Black or white are equally emissive. But polished shiny surface has really low emissivity. I think we should avoid clear ano of aluminum for high power flashlight as it can’t radiate heat to environment fast enough.
I think all color will be very close in emissivity. Just that the clear ano coat that maintain aluminum silver shiny surface will have very low emissivity.
It will be great if a proper test done on them to confirm or end the disagreement.
