What’s the advantages of these sft40? I read the data sheet but I don’t know what to make of it.

Factory dedomed SST40 which gives a good increase in range
Any chance of warmer color temperature like 5000k or 4500k SFT40 being available for sale?

Thanks!sounds good.
How about that fct40? Edit: I meant fc40

If this follows what happened to the SST40, here may be a 5000K at some point but not lower, and only low CRI versions.
I really enjoy the balance between flood and throw in SST40. I guess SFT40 will be a bit floodier than CULPM1, but I wish someone post a beamshot comparison.
Looks like the SFT40 has 4 bond wires. Not sure I’ve seen that before; a bond wire at each corner of the die. If that is the case that should mitigate the burning bond wires failure mechanism of the SST40.
Thought that was only with the SST40 Gen 1?
Simon Mao: flightless22:Simon, can you re-upload STF-70 datasheet and SFT-40 datasheet if you have it.
Hi Simon, thanks for the datasheets. Can you sell us sft-70 leds also?
SFT70 LED will not be available until next year

I have put forward this suggestion to the manufacturer, but I think it is difficult to implement.
Is the SFT40 LED going to be available for the Z1 and other flashlights?

I don’t know, maybe later versions are tougher. Even when they did fail by burned bond wires it was at >8.5A, so it was usually not a problem, but it will still be nice not to worry about that failure mechanism.
Does the SFT40 fit standard XML mounting stars (MCPCB)?

I just ordered mine and don't have any on hand, so I can't say for 100% positive. However, the pdf datasheet shows the die size as a 5050 which is the same as Cree XML.

Thanks Simon. Will be looking forward to that one!

The SST40 does, so this should as well.

yes,
