God damn it, I have good news and slightly less good news.
Good news:
- The FC30 can be made to work both on 6/12V MCPCBs, similar to the Cree XHP50 layout(this last one is very important, we don’t want 2 wire shenanigans once again).
- The FC60 can be made to work in 6V, with a regular connection layout
Slighty less good news:
- The FC60 can only be made to work in a single voltage currently. There are plans in the future to make it work on 6/12V MCPCBs, but that is currently not the case.
In that sense, the FC60 will only be made in 6V since it’s the most commonly available voltage for XHP70 style LEDs.
Acebeam and thrunite like to use 12V with XHP50/70 for some reason. But yeah 6V is probably more common.
edit : IMO that makes the FC-30 much more attractive for the 1st group buy since full XHP compatibility is really important and if the FC-60 can be made so in the future.
Armytek does the same thing for XHP50, which in the past I assumed was so they could use the same driver in XHP35 and XHP50 lights. I’m not sure about the XHP70 Wizard though.
They use quite powerful drivers and seem to be quite efficient, asynchronous doesn’t seem likely, I only have one thrunite with XHP, thrunite T1 (12V) :
Uses the MP3429 (synchronous), actually choising 12V makes sense here considering how thin and long the output trace is, it seems to go in between the USB port and the inductor (PCB seems to be 2 layers).
Like, the bigger appeal of the FC30 vs the XHP50.3HI as an example would be the fact that we can actually choose a good tint from the start and the good guaranteed Ra9070 rating.
Well, I guess you guys and gals make a good point.
That is interesting… I have 3 Convoy lights with the GT FC40 and all of them are very good tints and no green in any of them… Is it a batch or generational thing? Mine are older.
@mattlward basically, because of the very small sample batch, I wasn’t able to control tint binning and whatnot for a reasonable cost, which means there is no tint binning.
It varies badly
Production batches should be a lot better in that regard with specific tint binning.
“it is normall that the FC30 or FC60 has only about 45lm/w efficiency” “not about the sample production or mass production”
This is really an interesting turn of events.
I can accept lower efficiency because it’s domeless high CRI, but not 45lm/W at full rated power for the FC60 Ra9080 (2500lm) vs 75lm/W for the FC40 Ra9080 at almost 15W less (3000lm) by djozz’s compensated measurements.
It’s actually rather interesting how this differs. There has to be a reason for why this difference is a thing.
All because I wanted to make some light LED stuff from a newer LED did I ever end up on this with some partners online
The tale of BLF
I’m just waiting for more details from Getian at this point.
