Since titanium has worse thermal heat dissipation than aluminum, would it make more sense to add the boost driver here?
I bought the aluminum D4K with the boost driver add-on. Compared to the FET driver, the maximum output is lower. On the other hand, the output is better regulated. Is there any chance to increase the maximum current? I think someone mentioned 2A per LED as the default current.
It depends of the colour and Cri of the 70.3 Hi LED … i measured the Lumen of my D1v2 (almost same like KR1 but with sideswitch) in the first second in Turbo as follows:
Hi Hank!
Could you please tell me, do you plan to update your boost driver? I really want to have increased efficiency and not cut off turbo mode at the same time. Maybe boost + Fet or a new inductor?
To be honest when I heard about the new d4k development I expected you to modify the body enough to accommodate a larger inductor and give more than 2Amps per LED.
In addition, Jack firefly will soon release new flashlights with the updated Lume X1 driver which looks very promising.
You may also heard about the development of a new driver from thefreeman. Maybe you plan to take some ideas from these projects or already in the process of developing an updated driver?
Please share your plans on this topic, for me personally, it’s much more interesting than the new battery sizes and case colors.
Thank you!
I did calculated it earlier, it's not physically possible, the head opening is to small. The walls would have to be 0.3mm or thinner.
It have to be new model, with new bigger head opening, that isn't compatible with the normal D4v2 tubes (just like in the D4K case).
