Wurkkos DL10R Dive Light - 4500 Lumen Super Bright Underwater Flashlight with Magnetic Rotary Switch 100m Diving Depth Scuba Dive Light,IPX-8 Waterproof,100000 Hours Lifespan Charger for Under Water

Nothing wrong with it.

Looses power quickly and clumsy

Its main use for me has been cleaning the pool up after the kids at night, or as a care free light I can let the kids play with in the pool without the worry of water intrusion/damage (had that happen with a Maglight and a few cheap no name “waterproof” lights). Wurkkos made a name for themselves with their dive lights, and this one continues that trend. Small and easily fits in the hand, simply user interface, to change settings the button has a good amount of distance to travel making accidental button presses few and far between, and comes with a nice strong lanyard to attach to your wrist. Let alone, as you should get with a flashlight, a superb beam of bright white light (no uncomfortable blue tint). Great build quality, rechargeable battery, and best of all, this light will not break the bank like other lights ( I dare say this is THE best value in dive lights, given the current coupon, from a known name brand).

Excelente producto, carga rápido, la iluminación es intensa, viable para practicar buceo, al cargar se calienta pero afecta su funcionamiento, tarda en llegar el pedido 10 días

I finally got a chance to use this light and it definitely is good quality for the money. The only issue is that the button is too easy to hit accidentally, so you want to store it with paper between the battery and connection. No big deal considering the price.

If there's one thing I like about this diving light, it's the simplicity of it. It's a no-frills light, without all the extra, unnecessary features. The packaging is standard for Wurkkos, with everything tucked neatly inside. Not only does this light come with the 21700 battery installed, but it includes a USB charger as well! It also comes with a strap/lanyard that has a rubber sleeve on it for comfort, extra o-rings, an 18650 adapter tube, and instructions, of course. If you're familiar with diving lights, you'll recognize the magnetic ring switch. If you're not familiar with diving lights, this magnetic switch is used instead of your standard button. This switch operates the light by use of a magnet, mitigating the need to run wires to the switch, thus allowing the body to be completely sealed. This switch has 4 positions: off, low, medium and high. It's as simple as that! In regard to the size, it fits right in the palm of your hand. Like most of the lights I own that use a 21700 battery, I find that it's not too big and not too small. I chose the 2700K over the 5000K and boy am I glad I did. It gives off such a warm glow, it reminds me of a sunset or campfire. If you've never had such a warm temperature light before, I recommend getting one. In a world of bright white LEDs, something just feels peaceful about it.

So weird ... I bought this as a backup light. For some reason as it is on, about every minute, it flashes off then on twice. It happens at any power level. It happens whether I'm holding it or it is sitting on a surface. I will still use it as a pure backup light but this "feature" is very annoying. The battery is fully charged. I have not used it yet on a dive ... will be end of May.
