I just got my SK05 Pro with the Nichia option. It's quite a beast!
The spot channel on turbo competes with TS 28 for throw. Far away the Wurkkos is noticeably brighter, but at medium distances the hotspots look similar. Wurkkos has a more gradual transition into the spill and the spill is quite a bit brighter, which the photo doesn't really show.
Add the flood and the wall of light from such a small light is just something else!
Wurkkos is actually putting out a bit more light than flood + spot on the SK05 together, but at this forest path, with the snow the different beam profiles, the SK05 feels twice as bright! The exposure is locked on these photos.
With my uncalibrated testing setup the spot puts out 1580 lumens @ turn on and just over 1400 @ 30s. Flood starts at about 2800 and drops to just under 2600 @ 30 seconds. Both modes start the stepdown shortly after.
Flood + Spot together start at just about 3500 lumens quickly dropping to 3200 at 30 seconds. In the momentary turbo max mode the flood is outputting about 85% of it's single turbo and spot about 65% – about 2400 lumens come from the flood channel and 970 from the spot. Uncalibrated stuff, so I'm probably off by few percent, but possibly by more.
My only disappointment is the low modes. SK05 Pro manual says I should have 50 lumens on low in flood channel and 40 in spot. Mine starts at about 140 lumens in flood and 110 in spot. Way too bright. Do all of these have such bright low mode or is it just the recent batch? Add a 4th setting with a proper low and a moonlight on the flood channel and I would EDC this even when wearing a suit :D.
