The light will probably change, but here it is next to the Astrolux S43S, Wuben TO46R and Acebeam EC65.
Happy to report that the output specs are met. 1.5/11/55/250/1200/2500 lumens (tested with 30T).
Also love the momentary turbo from off or on with a long press of the W-switch.
I hadn’t noticed that before. This will be awesome for my evening walks. I can keep the light on low level while I’m strolling around but jump to full power when I want to look for critters ahead on the trail, and drop right back to low again.
Definitely buying one of these.

Thanks Maukka. Have you measured the lumens too?
I bought three TO40R and one TO10R and I like the light but my biggest complaint is how frustratingly difficult it is to locate the buttons in the dark. They really need to do something about it. At least make the buttons another color instead of black.
Lumens are on my previous post.
Happy to report there’s no visible flicker on any mode. Well, I was barely able to make it out on moon with rapid eye movements while bouncing the light off some reflector where it created a very small specular highlight. But couldn’t see it under any normal circumstance. Other modes, no chance.
Oh those lumen numbers were so perfectly rounded I those were manufacturer’s specs. The jump from 250 lumens to 1200 lumens is too much. I wish they have a max sustainable lumen mode, probably 700-800 lumens, to make the light more practical
The switches are backlit, but they’re only lit when low on battery or charging.
I like how the light doesn’t even allow high modes when the battery is low. It just cycles the lower modes as if the higher ones don’t exist. Until only moon works. Makes it easy to notice when you’re running out of juice.
Those are very thoughtful features but regarding the difficulty locating the buttons in the dark, they should make at least one of the buttons white and have it illuminated constantly when off. For those concerned about battery drain, they can just unscrew the tail cap slightly to lock it out.
On the new Wuben E05 that I recently reviewed, they’ve come with a more or less nice situation, making the pocket stick on the opposite side of the switch (on the head). It is not a perfect solution but it helps to locate it everytime you pick the flashlight!
BTW, thanks maukka for the tests and information! :+1:
That’s what I typically do with side switch lights: Turn the clip to the opposite side of the switch and you’ll easily know where the switch is.
The TO50R has a super efficient design. In the 250 lumen mode it clocks in at over 10 hours with an average system efficacy of ~125lm/W. This is the highest of any CRI90+ light I’ve tested. Regulated for the first 8 hours and slowly declining after that until stepping down to 50lm for the remaining runtime.
Can you confirm if this light flashes S-O-S correctly? I am rubbed the wrong way on Wuben with their A21 flashing S-O-O instead of S-O-S. Seemed like a great gift light for my father but now it’s just an embarrassment. Great feel, but really… Probably never buy another Wuben.
I can confirm the SOS is correct.
Thank you the,
i can deal with it, if its in CW available… :sunglasses:
You must be pulling my leg… :sunglasses:
This light will be NW, 5000K, 90+CRI. No other versions planned.
Maukka, is there any temperature regulation or preset stepdown timers on the higher modes? I really hope they don’t have any step down timers.

It’s temperature regulated. It isn’t as sophisticated as a really well optimized PID, but it stays brighter longer when you keep it cool. Even bounces back after stepdown if you manage to bring the temperature down enough. At some situations this may result in slow oscillations as the light climbs back to full output and steps back down after heating up again.
Without cooling on turbo and high my sample steps down to about 820 lumens and stays there in room temperature (23c) without additional cooling. Surface temperature is about 50 degrees. Most lights this size can’t retain 800 lumens without cooling or burning your skin.
Thanks for the graph! I think if the light was set at 1,200 lumen mode, the oscillation would be farther apart and less pronounced. Maintaining true 800 lumens is really good for this size light. But it is 21700 host so should have more mass. Someone should suggest to Wuben to add a sustainable 800 lumen mode.
