Wouldn’t a 26650 high output Golisi do just fine?

Interested.

Thanks,

You can use a 21700 in this light. I would use a 2mm copper ring just to be safe though.

Edit: just tried one ring…it works but 2mm is a bit much for this light. Maybe 1mm will be better.

May I ask a stupid question: it probably is very stupid cuz if it wasn’t someone would have asked it already. I am sure this new ft03 will be an amazing throwy light and I will buy it gladly but it will still have a huge ft03 head / large size which will be its main drawback. Why not put the SBT90.2 emitter into a thrunite catapult v6 instead. As is it out throws ft03, so I presume with a new emitter, same reflector, it will outgrow the new fr03 too . Yes I get it it will heat up faster due to smaller head/mass but I am sure many will agree to deal with shorter turbo times in exchange for an attractive small size and a super long throw. Or a v6 clone from mhvast instead? (forgot the model name) .

Is the answer the cost of v6? Or some legal difficulties, thrunite not agreeing to sell their modified lights?

Or is it that after we all buy the new modified ft03, next week, the modified catapult 6 group buy will be announced so they we will be spending more of our money on the same ( fubclionally) thing? I honestly and sincerely asking as I don’t know the answer. Can someone shed light? ( pun intended)
Thanks

No, Catapult V6 is not throwier than FT03.
Catapult throws 151-195 kcd depending on who measured it while FT03 does 190-263 kcd.

And Catapult comes stock with much throwier LED. SST-40 is awesome for throwers when it’s dedomed - but in FT03 it’s not. So FT03 with mediocre LED outperforms Catapult with XHP35 - which is very good.

Overall FT03 is going to throw significantly farther than Catapult V6 with any LED - precisely because it’s larger.

I expected ft03 to be throwier than catapult before I bought them both but the advertized throw numbers say otherwise, even though I didn’t measure the candela myself, I guess I can now that I have a lux meter. But… when I compared in the field , catapult, granted having a much smaller hot spot seemed to illuminate objects better. Of course with a larger hot spot and corona , the eye/ brain gets easier time making out that the objects are and the end result is often times more favorable with the ft03, but the actual illuminated spot appeared brighter with catapult. It’s hard to believe the delta you are quoting betweeen the two, but by virtue of being a human being, I could, of course, be wrong

Ok let’s say even if it turns catapult is slightly less bright ( i stilll can’t imagine it being much dimmer than ft03), it make sense to create a much smaller light with a slight shortcoming in the throwiness. At this point I still believe the catapult somehow throws father but inside the very small hotspot though . Did you compare same tints?

Does the large die area mean that the light will have a decent amount of spill, or are all those lumens concentrated in the hotspot?

According to what we’ve seen in the NI40 it should have a similar sized or maybe a tiny bit bigger hotspot that the SST40. The spill will of course be brighter as well.

In theory:
Spill angle is pretty much determined by the same regardless of emitter.
Spill brightness is proportional to light output, depends a bit on LED emission pattern but both LEDs have it similar.
Spot size is proportional to apparent die size. SST-40 has a dome which pretty much doubles its apparent die size. So both LEDs shoud produce similarly sized spots…but SST-90 will be much brighter. :slight_smile:

BTW…How does FT-03 spill angle compare to BLF GT Mini?
I care about reflector lights that are not too deep, so when I walk and have the spot directed forward the spill illuminates the road just before my feet.
