It certainly isn’t new, but new LED choices get added frequently

haze;
Will these be the same instructions for the CONVOY KW CULPM1 TG 8 amp?

The Convoy’s drivers for SST40 (both 4 modes and 12 groups) don’t 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 Lumeniac’s updated review the C8G regulation IMHO doesn’t look significantly better or worse than the M21A with SST40 or the equivalent C8. Nobody posted pictures of the updated driver, so we aren’t 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 it’s natural that regulation with a linear (or buck) driver will be worse.
I don’t know why we are talking about the SST40 in this thread, but the Osram white flats have similar foward voltage to the SST40.
Thank you!

Is there a way to SMOOTH RAMP this and the L21A?

Has anyone ever had their C8+ just flash when they attempt to hit 100%
I have a OEM NCR18650B inside it and it just flashes when I hit 100%, The beam doesn’t stay on.
Thank you very much,

Either the battery is too weak to power the light at 100% so it’s 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.
