Review on 🔦 Wurkkos DL40 5000 Lumen Dive Flashlight: Ultimate Brightness for Scuba Diving Adventure - Samsung LH351D LEDs, IPX8 Waterproof, Rechargeable Batteries Included! by Ken Perry

The Wurkkos DL40 is pretty much a complete set - comes with 2 26650 batteries with a total capacity of 10,000 mAh, which means a long life, the instructions indicate more than 3 hours at maximum output (5000 lumens). It comes with a lanyard that can be wrapped around the neck, a USB charging port for the included universal charger, 2 battery adapters if you wish to use the more popular 18650 batteries instead of the included 2-26650 batteries, 2 spare O- wrestling . , as well as instructions in several languages. The light is an underwater monster: turbocharged to 5,000 lumens/m², it is IPX-8 certified and can be used underwater to a depth of 164 metres. The luminous intensity at the hotspot is 38,000 candelas, which means that objects at a distance of around 400 meters are illuminated. I tested it under running water and under water in my bathtub and it passed with flying colors - perfect working without water in the light afterwards I also like the quite wide beam profile that the 4 Samsung LH351D emitters offer - that's always very important to me so I can see well around me with a good combination of outflow and outlier - yes it has a higher center of intensity in the beam profile in case I want to see the detail of the object further. The color of the light is warm (5000 Kelvin with a CRI of 90) which allows you to see objects better and for better color rendering, especially underwater, so I'm glad it's not cool white. Of course, the flashlight has thermal regulation to protect the light from overheating - as soon as the driver temperature reaches 50 degrees Celsius, the power is switched off. although it will decrease, but the more decent the size of the head, the heat sink will do its job and extend the full backlight mode longer. Also it won't be a problem in the water at all as it always stays cool in the water so the light level in the water will be pretty much a controllable intensity! The biggest plus of the Wurkkoss flashlight, including this DL40, is in my opinion the ease of use. A short click and long click and hold to turn off. Each quick click toggles between 4 intensity modes including Turbo - that's all, and very easy to get used to, very intuitive. The flashlight has a memory mode and next time it will turn on in the mode it left, which is very convenient. The mount has 2 o-rings installed on either side where it opens which is meant to keep water out and it has 2 pairs of o-rights which I will probably never need unless in one few years when the rings are installed if spoiled . Can't wait to dive into it - I've bought a Wurkkoss flashlight in the past, the weaker one, and was very happy with the purchase, but this one was 2000 lumens, this one was 5000 and it can light up anything and when you need it - a real animal in the water or outdoors. I recommend! And at the end of my pros and cons list, the pros definitely win: PROs - Very high intensity, more than needed to illuminate objects, whether from the water or inside - 5000 Kelvin color temperature and 90 color rendering index, which allows you to better distinguish between colored objects - Complete package, equipped with everything you need to work - 2 included 26650 batteries with a combined high capacity of 10,000 mAh - Good beam profile with plenty of light flow to see around you and a combination of decent throw for more distant objects - Works well thermal regulation for flashlight protection, good heat dissipation and controlled modes underwater as the light never gets hot there. What I like the most is the ease of use, simple short clicks to switch between modes and long click to turn off with save enabled. - I'm very glad the light doesn't come with a built-in charger as the extra hole can allow water to get in. Instead, remove the batteries and use the included charger. CONS I'm having a hard time finding cons, some of which are pretty much unavoidable and don't pose a real problem, but I'll list them anyway. operation) - the flashlight is not super light due to its size and is mainly powered by 2 batteries (but you should expect a longer runtime here too, and the weight in the water doesn't matter) - when used outside the water has the turbo mode does not have an adjustable capacity, so over time the illumination decreases due to the heating of the driver - this is standard for all modern flashlights and a protective mechanism, this is inevitable and does not pose a particular problem. after the head has cooled down a bit, can the fill light can be reused - I personally prefer a different lanyard design, but that's extremely minor and subjective
