Can the C8+ with 2700k SST-20 handle the 4.8 amp driver on some of the hotter models? My current one has a 2.8 amp driver and I was wondering if a driver change would make much difference in light or just heat.
So yes, up to 5A can be considered a great turbo mode. In any case, due to the high emitter Vf achieving such current with a linear or even plain MOSFET driver will only be possible under optimal conditions (high battery voltage, low component resistances and etc.).
P.S.: this or that, these are max 5A linear drivers.
I wonder which of Convoy’s flashlights now use “button” on the head (driver) side instead of “spring”.
I have the S21B with SST40 and S21B with CULPM1 (6Amp driver), both use a spring on the head/driver side.
I have the Convoy L21A with XHP35-Hi, and it uses a spring on the head/driver side.
But on the Convoy L21A with CULPM1, it uses a button on the head/driver side.
I suppose it got confusing whether people like reverse or forward clicky…
The earlier batches of Convoy M21A (SST40) and Convoy S11 (XHP50.2) used a forward-clicky tailswitch (I still have these 2 models with forward-clicky version).
I have since then tried another Convoy S11 (SST40) and this S11 now uses a reverse-clicky tailswitch. (I could interchange the tailswitch of the other S11 to make one forward-clicky or reverse-clicky type.)
I’d like to change my M21A (SST40) from forward-clicky to reverse-clicky, but am not sure if it’s available (the reverse-clicky tailswitch that fits the M21A).
I suppose I’m more used to using reverse-clicky type tailswitch flashlights.
For multi-mode lights, reverse switch makes more sense. And for 95%+ of people it does as well. I understand why it’s the standard. There is however a distinct market and application for forward switches…
Ideally,a forward “tactical” switch should have a secondary method to change modes. Either with head twists or an e switch that only functions as mode switching.
Convoy used to make the L4, which is a form factor very close to what I desire.
If the grip ring was removed from the tailcap and offered as a removable rubber version, and it had a more ‘proud’ tail switch, then the rest is mostly cosmetic preferences.
On that point, less is more, and I rreaally miss the styling of old eagletac, nitecore, 4sevens, and even fenix (original tk11) tactical lights. Sleek, aggressive, attractive, and functional.
Lastly, if a 32mm - 44mm - 60mm head diameter series with deep, quality reflectors and thin bezels (maximizing reflector area per head diameter — like the C8 and M2 exceed at (m21c not so much)) and taking cues from Amutorch designs that keep overall length in check, we could have a winner in my book.
Problem is, you make the bezel too thin (especially Al and not SS), and any good solid bang can bust the glass and ruin the thread. A thicker bezel, especially made of SS, makes the front end of the light almost a hammer-head in ruggedness.
Even in a padded case, I accidentally dropped my camera maybe 2’ (if that) onto the sidewalk, and the oblique-angle hit just the right way not only shattered the clear (“UV”) protective filter, but also bent the flange enough that I can’t even get off the outer ring from the filter.
Well, so much for padded cases…
In a flashlight, if you want it to be “tactical”, you need to be able to crack open someone’s melon with a good hit. So you don’t also want to bust the front glass and bend the bezel, etc.
There are clearly limits to thinness and the tradeoff with ruggedness. I think the m2 has it right though. I think thinner would be an issue but don’t see much practical advantage going much thicker. If you have to chisel your way out of a jail cell then maybe you have bigger problems anyway. I’m personally not willing to experiment with my sample, but I bet the impact would have to be quite severe to render it inoperable.
