You should take in account, that flashlight producers use different batches of LED for different batches of flashlight. So, and SST20/4000 in late ROT66 ii could be different ))) and XPL-hi could be changed for different tint grade without any mention.
As for me, greenish in my ROT66 ii not as awful as some… other….
And as i see, in same lenses SST20 is much thrower then XPL-Hi. So, if you want to use 66 as outdoor light, even with throwy lenses from complect SST20 would very possibly beam for longer distance, against XPL-Hi.
