I would say the XHP70.3 is a very floody emitter due to its large light-emitting surface of 49mm^2^. I don't have an SFT40 light (yet) but the tiny 1mm^2^ Osram in the D1v2 blows away the XHP70.3 D1K in terms of throw, even with less than half the lumens it has more than 5 times the candela. The SFT40 is 16mm^2^ so it would be somewhere between those two extremes, probably closer to the Osram. In a light like the K65 that has a big reflector and drives the XHP to its max power, you can still get a lot of throw from the 70.X emitters. The K65 does 2x the candela of the Osram D1v2 with a larger hotspot, it's a light cannon! I wish Acebeam would bring the K65 back with the newer generation XHP70. The 70.2 has a yellow fried-egg beam with a green corona. The 70.3 has a beautifully clean beam with no tint-shift (orange-peel reflector helps that a bit)
