Tektite H2113 Seeker light?

[DetectorGuy]

Now that I started looking at Sartek lights I might switch my thinking. Sartek has a lot more variety of lights to choose from. The focusable head is a selling point for me to go from a 3 degree pencil beam for plain diving, to wide flood for video... I just don't see how I can go wrong. If the 21 is too bright for the local turbidity then I can just click it down to 13 watts. I do realize that the further you can project a beam of light, the more particles will be illuminated, but do you think a high wattage light will cut through some of this "fog" or not? Maybe its like driving in a snow storm with your high beams on and I will be disappointed. I am still thinking that a person can not have too much light even with the back scatter. If you have seen any of the video I have taken using a UK D8 dive light, you can see that I need more lighting horsepower. For an extra few hundred bucks I can get one with a 15.6 amp/hour battery that will last me all weekend. The downside of these 15.6 amp/hour batteries is that they come with 3 separate 5.2 amp/hour cells and 3 chargers (that come with it). The other question is whether or not to get the wet connection cable or not. Right now I am thinking that for the extra 100 bucks for that, I can do without. I like redundancy, but I do not see my self changing HID bulbs underwater or changing to a fresh battery underwater, so the standard cable is probably ok.
