Before i pull the trigger on this one, i need some info: does it hold High or is there a stepdown from High? If yes, what is max sustained output it can hold?
It holds high, when the temperature control point is reached, the brightness decreases as the temperature increases.

I own a TS10 and a WK30. Both are really nice flashlights.
The TS10 is a great EDC and the WK30 is a whole lot of fun - it’s my only ‘real’ UV light (the two others I have are keychain lights with relatively weak UV sidelights) and every time I turn it on, I’m surprised by its output.
That being said, I’d like to see an upgraded WK30 with USB-C charging, 21700 battery, bigger reflectors, ZWB2 filter, slight UI tweaks and maybe a white emitter with more throw than the LH351D.
The WK40 looks promising, definitely curious to know how the UI works.
Both of these look like attractive lights. The WK40 stands out to me in particular because there are so few RGBW lights on the market, usually with only one level per channel.
