Hello Wayne et al,
I have a Blue Shark (and Remora), those were shipped on 06/Jul/2009.
General questions:
1) Is the copper "c" electrically neutral? I wish to connect it to the flashlight body (connected to negative). Is it okay to have it electrically conencted as well (by touching or conductive epoxy etc)?
2) Which changes happened since then to the Blue Shark and Remora? I may have a "SOS version" of the Remora and have thermal runaway with the installed diode on the Blue Shark. Anything else I missed?
I wish to mod a 18650 flashlight (JetBeam RRT-21, a lot of heatsinking mass), I have AW 2600 cells here (Vmin 2.8v?).
If in any way possible, I wish to use a Nichia NC4U133A UV LED. Vf 14.9 (17.3v max!). Imax 700mA, I would mostly use the "low" and "middle" mode of the Remora.
3) Is such a configuration (Single LiIon, 14.9v, 700mA) possible at all? I understand I am right at the border of the specs, and beyond the advertised/guaranteed limits.
4) Would I get around swapping the diode?
5) Alternatively, 500mA Imax?
6) Alternatively, 2x RCR123a input and 700mA Imax?
I read a lot on this topic, but still am feeling unsure. A definite answer would help me a lot.
Thank you for your help and patience, much appreciated!
Manuel
