Iâd recommend getting pan head screws to replace the flat heads. I had to in my M2 because the factory flat heads forced the emitter of center. What then happened as an assembly is the emitter was âcenteredâ in the hole, but the reflected wasnât sitting flat (off axis). This caused asymmetric artifacts. Pan heads allowed me to center it AND fully clamp it down.
Thank you for your input. Can you provide a link to the screws so I get the correct ones? This would be a great solution, I entirely forgot where I saw the comment and what the screws were
The Convoyâs drivers for SST40 (both 4 modes and 12 groups) donât use PWM. That means better regulation and efficiency at modes below 100% than an equivalent 7135-based driver. That also avoids black lines on cameras.
On Lumeniacâs updated review the C8G regulation IMHO doesnât look significantly better or worse than the M21A with SST40 or the equivalent C8. Nobody posted pictures of the updated driver, so we arenât sure, but efficiency looks worse than the SP35 buck driver. He compares it against an 8*7135 C8 with XP-L HI but the XP-L HI has higher forward voltage than the SST40 so itâs natural that regulation with a linear (or buck) driver will be worse.
I donât know why we are talking about the SST40 in this thread, but the Osram white flats have similar foward voltage to the SST40.
I sanded down the centering ring in my Osram C8 to focus it better. It has the petals around the hotspot, but they are mostly even, instead of on one side of the hotspot like it was out of the box.
If you want the throw of the Osram emitter with a perfect beam you need one of the lights with that fancy TIR optic that Acebeam uses on the E10, and L17.
Either the battery is too weak to power the light at 100% so itâs voltage drops below the low voltage protection threshold and the driver reacts by turning down/off, or if the battery is protected it might be the protection circuit kicking in for the same reason.
