My Convoy S21A with SST-40 5000K arrived today, so I went white wall hunting.
I assume it is this emitter: SST40-40-WDS-F50 FLUX: N5 Color: DA Voltage: VJ CRI: 70
At 100% does not look green even next to my E07 219B sw45k. Very likely below BBL.
At 30% it still does not look green even next to my E07 219B sw45k. Probably below BBL.
At 0.1% and 3% it looks green/yellow next to my E07 219B sw45k. Probably above BBL.
I did not do any measurements though. Spill is noticeably cooler than hotspot and corona.
I like rosy tint, and I can instantly see green/yellow tint on some of my SST-20 4000K lights. I don’t see any green tint at 30% and 100%, it looks “pure white” on a white wall.
Thank you for the feedback. Looking forward mine! It’s probably the best tint sst-40 I’ve heard about. When used outside that little bit of green/yellow at low currents should be acceptabl….
However, I doubt slicing the dome would improve things. All the 6500K SST-40 dedomes/sliced domes I’ve tried all went horribly green/yellow at lower currents. I’m not gonna try it again, unless someone has the balls to slice their 5000K ones…
Now that 5000K is actually readily available (unlike when the FT03 came out) I might be persuaded to give it a go… just gotta get a nice sharp blade and some washers.
Hi Simon. Prosperity to you! )
I checked the operation of the Convoy M3 thermal control, it worked at a temperature of 37°C on the surface of the head of the flashlight. I think this is very early, I would prefer the operation of thermal control at a temperature of ~50°C-55°C on the surface of the head of the flashlight.
Was this conceived, or is this a mistake and will be fixed in the future? Are the thermal control settings the same in all new flashlights?
But the function of thermal control itself is very important in flashlights, I was very glad when the thermal control appeared in flashlights Convoy
Thanks!
It’s probably 55 degrees at the driver; given the difference you’re noticing, 55 degrees at the front would be 71 degrees at the driver (and if there’s wind cooling the front, potentially even higher….)
After removing the NTC of the driver, the temperature regulation is gone.
I am very happy with it now, the light now works as intended, just full power on max (and yes, it does get hot after a couple of minutes, but still a lot better then the Astrolux FT03 though)
Probably, this is more or less a matter of (inefficient) thermal conductivity. If the driver gets hot like crazy but the host structure around it remains much cooler Simon should look for ways to improve the thermal transfer and dissipation. I could imagine that the driver does not make good contact to the M3 host or cannot dissipate the heat due to non-conductive materials.
I faced the same situation with my M3. No matter how often I restart the highest mode, it never really gets very warm on the outside.
