I had some spare parts laying arond so today I have modified Convoy S8 with Covex lens and SFT-12 driven at some 3.5A (don’t remember from where I salvaged the driver).
Soldered MCPCB to the pill to make it sit firmly
And resin glued the lens
Adjusted the pill depth to get the most focused beam
And as a result I got ultra focused narrow beam in a small flashlight without any spill which I like more than expected…
Sorry for the hopeless picture (I hate Samsung phone cameras). Trees at 45m. The beam is similar (in range and brightness) to NM1 with SMO but totally without any spill and round in shape… I really like it
