very powerful flashlight, it definitely does not last the hours stated. At full power, it might last just a bit more than half an hour

2500lm for the 100€ I got it, it's worth it, everything is good, at night there is nothing left, it keeps the city in sight, maybe a couple of hours at the end, it's powerful, you just have to be careful not to let it slip out of your hands in the sea

Very powerful but the batteries don't last as long as they say and it's very heavy! It's not good for spearfishing!

I gave 100 euros to buy this specific lens, I don't know what material it is made of but it has corroded and broken in many places despite taking good care of it! Another disadvantage is that it has been damaged by salt!

As for the light, it is indeed strong, but if the material is not good, what can you do with it?

First of all, I would like to mention that for anyone who does shallow fishing, therefore solar light is an issue, I consider the (real) 1,000 lumens (not to mention the 1,500 lumens) to be the minimum.

Furthermore, the saying "You get what you pay for" applies fully. Therefore, by having ~100€ to buy a flashlight (when entry-level ones cost ~20€ and top ones cost ~350€), you are aware of what you will get.

I am coming back after 2.5 months of use. As already mentioned, the button of the flashlight is pressed very easily, resulting in the flashlight often being turned on (inside or outside the water), with all the negative consequences that this entails.
Also, the "pressing" for 3 seconds to turn it off is not convenient at all, compared to flashlights with switch buttons (2 positions).
Finally, in terms of brightness, it is considered "borderline" for those who do shallow fishing or want to illuminate a chamber from a distance.

I have purchased the product in the photo, d26 1600 with the 26650 battery included in the box. Reliable flashlight, very bright and the o-rings seem to be of high quality compared to the xdive flashlights I had. The only problem that I hadn't anticipated is that because it doesn't have a two-position switch, I can't tell by touch when the flashlight is on or off between dives when my mind is elsewhere. It also takes 3 seconds of pressing the button to turn it off. Now I press it for much longer and occasionally put my hand in front of it to see if it's turned on. It has become a habit now. Another issue is that it requires caution during transportation and storage because the button is easily pressed and sometimes it turns on inside the car or boat and I find it on. However, the battery is a beast and has never let me down, I really don't know what they have done but it lasts a ridiculously long time. That's all for now. Happy diving
