[review] Wurkkos DL40 diving light

I have the DL40 and I love it. Let me first say that I took even Wurkkos’ non-diving lights under water for extended periods of time and they held up 100%. The DL40 is in my opinion the better Sofirn SP36 - the very same light color and pattern, a bit bigger reflector and the awesomeness of a baton-style light. If you can do without the deeper functions of Anduril and a million blinky modes you might prefer the DL40. It is just so much better to handle for longer periods of time. The movement of the very prominent magnetic switch is enjoyable in its mechanic nature. The build is massive but not overly heavy. This is the light I would take on a trip near the water. It covers land and sea use perfectly.

In fact I plan to take my Kayak to one of our beautiful rivers and stay overnight:

I will take 1x high powered light with good runtime and I dont see any better option than the DL40.

Here is my review:

BTW Wurkkos also has the WK20 in warm white which is more than nice underwater. I have two of those on my camera rig and the light color is just…mhm…

Awesome, thanks for sharing!

Oh, and did I mention that the DL40 is one of the lights I would hand to anyone and never worry that their lack of deep flashlight expertise might plunge them into some sort of desparation? A mechanical lockout that looks like the light stopped working. Or a blinky mode that just seems to happen and causes them a seizure before the can blink. The DL40 is a light that you can use when under stress and without your usual motor skills. There is a lot to be said about simple, rugged lights…

Markus, excellent video review. Thanks for posting it here. I got a kick out of your t-shirt. I work down the road from Corona, CA. Although I know your reference was toward the Corona virus, still cool to see you with that shirt; Small world.

Yup, there is something special about carrying a solid flashlight. It’s like a chunk of steel that shoots out massive light. I could build a man cave around this thing. LOL

Thank you! I ordered that T-shirt before the lock-down here in Austria. It got more expensive a few days later. I like that it refers to a place in California. I’d love to go to CA this year as well but my job in the medical won’t allow, it is not reasonable.

Aha, I did miss that one. Interesting underwater critters, too! Didn’t expect to see a cuttlefish. :laughing:

Yeh, got one, awesome light!

Yep, I mentioned that the UI is “simplicity itself”, and it is. No crazy modes to get trapped in, just on/off and modes. Only thing simpler would be a 1-mode on/off-only light.

Hello, can you please tell me what is the outer diameter and thickness of the rubber rings on the Wurkkos DL40 flashlight tube? Thank you.

DL70 is $50 now. Is it any better?

Yoiks… I’d have to find it.

That might be the one I let someone “borrow” a coupla years ago. I know it was a diving light, but forgot which one.

I’d just pop one off and measure it as best I could.

Unno. “Better” is relative.

Are the Wurkkos 26650 batteries good for the Wurkkos DL40 or other Wurkkos flashlights? Is it better to replace them with Liitokala batteries with a neodymium magnet between them for contact?

Owned a Wurkkos DL70 for a short period of time. IMHO there is nothing wrong with those batteries.
Personally I would not use a magnet in/around a DL40/DL70 because the switch is operated by a magnet.

Fooey. I use the Sofirn/Wurkkos cells on the daily. Nothing wrong with them. They’ve held up as far as capacity, etc., and I haven’t had any major problems with 'em.

Using hotrod cells is fine if you like to play the numbers game, ie, run 'em hotter for like 2% more light that no one could tell any visual difference even doing an a/b test, let alone trying to tell any difference by swapping cells.

Thank you, but are Wurkkos batteries protected? I saw a video on YouTube where one person said they are protected. I can order batteries from Panasonic made in Japan (green ones), without protection, but although they say 5000mAh, in fact tests showed ~5500mAh. Which ones would be better? Thank you.
