I have the Led Lenser D14 bought me to still have a small backup lamp while diving. And I must say that I absolutely satisfied bin at a 0-view-dive in a lake at us near the D14 was able to show what they can, and for the price and its size compared to professional dive lights from the house Kowalski she does not have to completely hide. I was really glad to have the D14 here because were much better read to her pressure gauge, depth gauge and compass, as with the vast Kowalski. One advantage of the D14 is also certainly their significantly lower weight than that of Kowalski, what is far more pleasant in the long run. Nevertheless, I would recommend the D14 not as the main lamp in dives with less or hardly any view as their jet's already very focused, and the light output accordingly is not so great as with a large dive light.
I can understand the D14 but still recommend to anyone who wants a good and relatively cheap second immersion lamp.
