Now on auction in aid of LifeNRA - Mt First Creation: Steroid 4 Dive Light Test445ft
This is my first creation on my lathe. Being a diver myself and a flashaholic i always wanted to have a very powerful LED based dive light in a small package, so this is what i came up with.
It's 124mm long and 75mm wide at the head. all walls are at least 5mm thick, the glass is ultra clear and 10mm thick. It is machined out of a solid piece of aluminium ( not aluminium tube ) so there are only two water entry points i.e. the tailcap and the front glass thus removing an extra entry point behind the head. the tailcap is sealed by two 3mm thick o-rings and is held in place with 2 heavy duty stainless steel clips rather than thread. the front glass is sealed by one 4mm thick o-ring placed behind the glass i.e. the greater the pressure, the greater the seal. the glass is held in place by a flange with 8 stainless steel allen bolts. The switch will be a magnetic reed switch ( i still have to find a place for it )
as you might gather it is overengineered purposely to make sure that it will be very hard for it to physically fail.
It will be using 4 x U-bin Lux3's slightly overdriven and 4 IMS 20mm reflectors.
Approx 500 Lumens. It can use multiple types of batteries using different holders like 4x18650's ( protected or unprotected, aswell as smaller li-ion's), 1xC/D Li-ion, 4xAA/AAA ( Nimh, Primary or primary lithium ) and possibly some others. The actual space for the batteries is of 48mm diam. by about 70mm long so i guess one could even add an electronic and still have space left over. i think it will achieve over 2 hours runtime with 4x18650's ( i will be using 4x18650's in this one).
I will be testing the body ( no LED's or batteries ) physically in the sea tomorrow up to 200 meters hopefully with no problems.
Here are some pictures. they have been taken by my mobile phone as my camera is in Norway at the mom, so please bear with the low quality.
It does have some imperfections ( though they may not be clear in these bad photos ) mainly due to me still learning how to use the lathe properly and some stupid mistakes i have made. But i guess it turned out ok.
Here are some comparison beamshots ( 3 meters from door ) with the Barbolight U-09. The steroid4 is only drawing 680mA ( 170mA per LED ) with two freshly charged 18650's ( in paralell ) for some reason which is yet to be determined while the Barbolight is drawing 1.5A ( 500mA per LED ) with a freshly charged battery pack.

If anyone is interested in it PM me as it is not being used.
Thanks for looking
