Re: Mt First Creation: A Dive Light ( Yet Un-named )
Longjohn: dunno about scubasun, maybe scubastar but dunno if that name has been taken
Slinco: Thanks
McGizmo: my mistake i thought U bin was speced at 120 Lum. ok so it's about 100 Lum avarage @ 700mA so if i drive them at around 800 - 850 mA i would at least expect 110 - 115 Lum ? so that's about 460 Lumens. about 10% - 15% optical losses leaves me with about 400 - 415 Lumens. Keeping it cool should not be a problem firstly due to the large mass of aluminum ( 750 Grams ). the heatsink is not a seperate part which has been glued to the body but it is the body itself as the entire light ( except for the tailcap and flange ) has been machined out of a solid aluminum rod. so heat should travel throughout the entire body with no bottlenecks except for the one between the LED itself and the body. Secondly it will be surrounded by moving water which should cool it down considerably. so i guess it should run nice and cool.
500 Lumens was very optimistic but i'm hoping output should come close to the UK Lightcannon which is my main aim, but smaller, sturdier, longer lasting and most importantly cheaper. When the K2's are available i guess 500 Lumens will not be out of reach though.
Mobile1: thanks, i will within a few weeks.
Tranquilitybase: Thanks a lot, it has a lot of character then hehe
Chesterqw: well aluminum cost me about $30, S/S fittings about $12, the glass about $13 and about 25 hours of work. dunno about thick O dive, it's kind of long.
