Any experiences or runtimes/driver info (@Wurkkos_Terry) on this new light? The switch looks super interesting and so do the emitters. It also has the USB-C built-in charger.

Hmmm, no word on runtime/regulation yet?
K. Weerapat just did a video on it:

The video had mostly two âareas for improvementâ. Warmer spot LED (SFT40) and better control of rings artifacts in the spot spill.
I have one more suggestion although I havenât seen this light yet: using a ZWB2 filter in front of the UV LEDs. I just head a chance to compare two UV lights, one with and one without a filter and the filter, by cutting most of the visible waveleghts, makes a tremendous difference in seeing actual fluorescence (as opposed to seeing the reflected blue-violet part that the UV LED also emits, when not filtered).

I agree, warmer SFT40 and ZWB2 filter would definitely make this a perfect âall in oneâ flashlight.
I would love to see an upgrade with the UI as well, so you can step down the brightness instead of the need to cycling through the brightness all the time.
Thanks. And the driver?
Just use the simple PWM driver

Hi Terry, I have one of these on the way and was wondering about something mentioned on the product page - reverse charging. Any information on amps for reverse charging? Thanks.
1 Thank
Yes, of course my man.
The amps for charging and reverse charging both 5V/3A.

On Amazon.com this light is listed as coming with a ball head. But this isnât mentioned or shown on the Wurkkos website.
Does it come with a ball head? If not, how can I attach it to an underwater housing?
With the ramping and red light modes it looks like it might well make a great amateur astronomy buffs field flashlight too. At the end of the night the very wide flood white light beam available would help find anything forgotten on the ground too during cleanup. It looks like a very versatile light for multiple categories of users.
I can now answer my own question about the ball mount.
I sent e-mail to Wurkkos and got an answer that the light does not come with a ball mount but if I requested it they would give me one for free. I ordered the light and they did send a ball mount. The mount attaches with a long bolt and it will not loosen if I try to turn it.
I attached the light to a housed underwater camera and used it on several dives. During the day I used the spot mode primarily and at night I used the flood mode (I carry several lights at night). I did not use the red or UV light underwater as it wasnât necessary for the diving I was doing.
It worked very well as a focusing light. It is bright enough for what I do, and I usually did not run it at full brightness. I donât care how even the light is. I like the switch, which allows me to turn the light on in the mode I want.
I ordered two more lights. I put a request for a ball mount in the order comments. Both arrived with ball heads.
This light is one third of the price of the next least expensive dive light I know of which met my requirements. Iâm quite happy with it.
I received one yesterday and it developed problems in literally a few minutes. Worked fine and then started having the LEDs blink at a relatively high frequency when I tried to change intensity in either stepped or ramping mode and the LED selection ceased working with the light on. No change after fully charging the battery. I have contacted Wurkkos regarding the problem and they assure me that they are sending a replacement light from China. The blinking LEDs did not change in intensity while trying to adjust the intensity. The light worked correctly for less than 10 minutes before failure so definitely a infant mortality problem. My background is in quality assurance and reliability testing in Silicon Valley for a division of Xerox years ago and I let Wurkkos know of my background when I contacted them. They did not ask for return of the failed light.
