Ehhh, to say the FT03S MIGHT further throw is a tough pill to take with the performance of the W1 chip in a similar form factor the K1 can be used as reference with a similar reflector size and with the already published projected CD of 510k~ for the FT03S I assume the W1 in the FT03 form factor would have similar performance give or take a few thousand CD.
There’s no way that the SBT90.2 will outthrow the W1. K1 does 650kcd so I’d say 550-600kcd 800Lumens for the W1 FT03 makes sense. SBT90.2 should do 400+ kcd 4500Lumens. Haven’t test it but will once I receive it. This will undoubtedly be the furthest throwing light you can get for the money. The question is that is the Lumen trade off worth it for the extra throw.
I’d prefer just the MCPCB and driver as I’ve got a dented blue host out of the box (couldn’t be bothered doing warranty claim) that I wouldn’t mind swapping over. But if that first X is a 2, I’m down.
(edit: I see that the SST40 5700K in lower lux bin is $2.09USD each per thousand at Mouser, and the CSLNM1.TG is $1.34 with same MOQ, same place so fingers crossed on that 2.)
