I too have had a delivery from Amazon
It is very nice looking (but wants to roll away, doesn't have much to hold on to, and that lovely shiny finish is asking to get scratched).
Then there is that lovely tritium tube in the switch. Oh yeah!
I've done a couple of very quick tests and the parasitic drain is a nice an low 6uA (26 years to drain a CR123). Outputs are nice, but so far I'm running it on a part drained CR123 so it is not giving the best representation of output levels. There doesn't appear to be any PWM used :thumbsup:
Nice job Lumintop, and thanks for this great giveaway.
