It is possible that our custom 1xAA BLF flashlight could have a programmable driver. As I mentioned in another post, Eastward YJ is going to look at the Akoray K-106 3-mode programmable light to see what they can do. So, since many of us are interested in a moonlight mode for the BLF custom flashlight, the question naturally comes up: How low can an Akoray K-106 go?
I have been experimenting with mine, and it doesn't really go very low. Even when I set the lowest mode by half-clicking before the ramping cycle even starts, the lowest brightness I can achieve is almost identical to that of the Trustfire F20 on low. I read somewhere that this is approximately 6 lumens. Any other experiences or tips or hard numbers?
Apparently it can go very low, I remember reading on CPF that the way to do it was to use multimeter probes as they could be moved more rapidly and could get it down to the 1-2 lumen area. Not tried it myself though.
The trick is to remove the switch and use a multimeter set to current.
Get it into programming mode then as soon as the meter shows a current, break the circuit with the probes. I managed 2 lumens with a 14500 but I've not been able to replicate this. Got the lowest down to about 6 lumens with an NiMH, 8 with a 14500 though a bit more fiddling ought to be able to drop it a little lower than that.
It is a pain to line up the clip when it comes time to reinstall the switch.
