It’s powered by included 46950 Li-ion rechargeable battery with 30,000mAh, to recharge you can use the USB-C cable. The charger for 18Wmax output, or discharger for 22Wmax output. So you can use a powerbank, phone charger etc to charge it. Or discharged by DL46.

The Wurkkos DL46 is operated by Magnetic Rotary Ring Switch, with a green-red LED indicating the power level. The power level stays on all the time, useful for cave divers to know the remaining power without having to turn it off and on. The indicating LED is poweful but does not disturb night vision.

The Rotary switch has 3 positions: High-Medium-Low.

It has been designed so that by turning left, or turning right to choose the light model use.

The leftmost position is turn off and get lockout mode immediately, or you can unscrew the body and interrupt the electrical contact.

It also include ATR Advanced Thermal Regulation, that kicks in at 60°C and reduces the output to cool the light.

The light features LVP, Low Voltage Protection, which turns the light off when the battery level is too low to operate safely.

Beam Angle: Center 17°; Flood 89°

What is the lumen when set to 17° angle, and when set to 89°?

Weight: 938g / 2.06lb

Is this the weight above or underwater? Give the weight for both, please.


Does it come with a Goodman handle? If not, do you sell one that works with this light?


What is the maximum run time at full power?

Is the output power adjustable?

What are the adjustments and the corresponding power run time if the output power is adjustable?

Do you have a company website? What is it?

 

[lostsheep]

Okay , I’ll test one for you.

DM me to arrange delivery.

N.B. A 30,000mAh rechargeable Li-ion exceeds FAA and IATA battery limits without specific written permission from the air carrier.

, since I was contemplating ordering at the launch discount.

The response to comment questions.
1. The last picture shows center spot is 17° and decent spill is 89°.
2. It's the weight above, we don't know how to test the underwater. Could you give recommendations?
3. We currently can't make a Goodman handle at low cost. The body will come with a 1/4 Inch screw hole connect handle always.
4. The full power run time above is 3 hours
5. Yep, there is 3 levels output 10w-50w-200w
6. Rotary the ring switch, just like you saw the 7 picture
7. www.wurkkos.com Wurkkos Official Website is

Sorry but you are developing underwater products and should have engineers for it. They should know how to either calculate or measure it. If not, tbh, I have a couple of concerns about quality.

 

[lucca brassi]

IMO : Have you ever wondered why no reputable manufacturer makes such CRAP ... a very serious question? Light like that is technically user useless ..... without even looking on quality of production. With that light you can not dive without sunglasses , you can not film or making photos because of overexposed and wild shadows like on moon , animals hide ......LOL .... then why for ?

How about using a luggage scale to weigh the light above water, then lowering it so that the torch is below water, not the scale, and checking the weight of the torch when it is submerged (again, don't dunk the scale underwater)?

@lucca brassi Ignoring whether it’s reliable/well made, because I haven’t tried on and can’t speak to that, underwater search and recovery (for artifacts, dead bodies, etc) in low vis environments would likely be well suited to a light that bright. There may be such as a thing as “too much” light in such a situation, but I have yet to encounter it. I could imagine even too much light could have a purpose, being mounted further back for use as a flood/more distant source of disperse illumination, but I don’t know.

If I ever get a chance to try a light like this, I’ll let you know what I think of it in practice, but I’m definitely intrigued. Some concern that, past a certain point, in cloudy water, you might hit diminishing returns. Doesn’t matter how much light you have if the effective opacity after three feet is 95%
