I bought this flashlight on 13/05/2026 and on the first dive it took in water. The o-rings it has are useless. When I opened the box and took the flashlight in my hands, I saw that the screw at the back was tightened all the way, resulting in the o-rings being compressed. If you buy this flashlight, change the o-rings immediately with new ones. I would not buy it again, wasted money.

My own must have a construction error. The wheel doesn't turn, I don't know if the whole head is supposed to turn. Besides that, from the first dive, it started collecting external salts. I washed it regularly. Two days ago, I forgot it inside the bag without washing it. The next day, all the color had been eaten by the salt and it had even started to corrode. On the other hand, it has incredible light for its size. And the fact that it comes with a charger is very good. Maybe mine turned out to be a defective model compared to the others.

So. I take the first one, in the first dive into the water. I turn it back. They replace it for me. The second one has a constructional mistake where the activation ring is fixed. It doesn't move. I turn it back. They replace it for me. I hope the third one performs better. Its light is indeed powerful and its size is impressively small.

Impressively small! It fits entirely in the palm of my hand. For its size, it has a very powerful light. I would give it a 5/5 for this (size/performance ratio). However, it doesn't turn night into day in the holes (I use it for spearfishing). It throws a good amount of light into the hole, but only to a certain extent. If there was a 4.5/5 option, that's what I would give it. For its size and price, I would definitely buy it again.

With the 2600, it lasts about 2 hours and not 4. The volume decreases by half after an hour. According to the manual, the test for 4 hours was done with the 3500 battery, which was stated to be included in the purchase. However, it actually had the 2600 and not the 3500 (now it states the 2600 after mentioning it), without changing the price of the flashlight. After half an hour of use in water, the brightness decreases (due to the overheating protection system) without any reason. It needs to be turned off to recover every 15 to 30 minutes.

Very powerful and reliable but also affordable lens for amateurs and for simple use! Value for money!
