In need of a new diving light

It's to bad that I saw the campaign to late (diving light broke down a week ago). Can you tell me what the price will be? Or perhaps there's a possibility to become a tester anyway?  Perhaps I can purchase with a discount and test it for you? Anyway I'm looking for a new light with high output and aswell adjustable output. I am a diver in the Netherlands so it's not always usefull to use full ouput in case of high algae ( they absorb all light and create a blinding screen). On the other side, it's always dark in our waters. If we can arange something it would be great! If not, I would like to thank you anyway for the creating of some of your other flashlights (owner of a  L25S and K40M)! Greetings, Freddy Jeurissen
