Well, the way I figure it is like this:
It is going to go in a
fivemega MegaTinger flashlight body,
and it will take the place of the XP-G2 in a Malkoff Stinger dropin.
My Dad retrofitted a stock Stinger charging base with a cottonpickers USB charger,
and the final piece is an LED which sits on the line between warm and neutral,
between red and yellow.
5C1 is orangey, 5B1 is yellow, 5A1 is pink and 6A1 has a reddish cast.
The fivemega MegaTinger is a robust host, the Malkoff dropin is solid in its own right,
the cottonpicker's chip uses a reliable CC/CV alogorithm, and the whole package with a protected
18650 will be dead simple and reliable.
I had a hit from a gentleman in Europe about a month ago, but hesitated and he sold it/put to
use in his own projects. Half of it is finding the LED, half of it is finding someone to part with one.
But I am patient.
I have waited years in the past for various builds/parts/accessories to show up.
