CONVOY C8+ CSLNMI

I’d 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 ‘centered’ in the hole, but the reflected wasn’t 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

Does the 4 mode comes with different driver than the 12 groups?

Anyone knows what driver they use for the 4 modes? And if it’s more efficient than 12 groups? As it says no frequency (pwm?).

Not sure about pwm but I’ve never noticed any.

Same driver used for both, just different firmware.

The no frequency puzzles me.Is the c8g SST40 more efficient than c8+?
As I read c8g have better regulation compared to 12 groups c8+?

THANKS Mr. FUNTASTIC :+1:

looking forward to that ASTROLUX thrower that mimics the T9R.

I LOVE NEW ZEALAND

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.

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.

M2.5 x ~4mm long. Philips pan head. Thread pitch is 0.45mm I do believe.

is the CONVOY M2 a new torch?
I saw one on YOUTUBE and it seemed to be an introductory video.
I have the L21 and the C8+, now I want the M2.

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

:+1:

haze;

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

Yes, same thing

:+1: :smiley:

Thank you!
I bought the 4 modes version. But it’s too simple. Should have tried the 12 groups version.

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.
