I hope that others find this useful.
There has been a good bit of myth about light which is understandable. A little information about my background might help. I am by no means an expert when it comes to light, I know people that have forgotten more than I will ever know on the subject. However I do have an industrial engineering background and have worked in the corporate lighting industry both as a consultant and employee.
When discussing light there is are complicated factors that affect what is produced especially when it is concentrated into a tight focused beam such as what we use for diving. Hopefully I wont make this too boring and will use related examples to simplify which wont be exact but should put things more in layman terms. As far as comparing LED & HID it is easier to just see for yourself with our light comparison videos & photos
Focus: Sorry to bust everyones bubble but there is no such thing as a focusable beam. Before everyone jumps on me let me clarify. Optics are designed to focus as much light output that they can collect within a specific beam angle. Without getting too technical because even beam angle gets highly technical all optics work at a specific point the most efficiently. When the reflector is moved from that point even a mm the efficiency drops considerably. The HID focusable head is a good example.
