How to use the BLF-A6

Click the button on the back and it comes up in moonlight mode (wonderful!).
Bump the button on back to kick it up a level at a time. This is all I ever use or need, but there are other features and tricks.

It is possible to set a mode other than moonlight for it to come up in every time, but for me having it come up in moonlight is perfect.

The following diagram purports to illustrate what the above text explains:

Modes and current draw

I got busy and measured current draw using a bench supply and obtained the numbers I give below. 
Mode 1  0.4 lumens  (moonlight)  3.4 mA  500 hours (20 days)
Mode 2  8 lumens  (low)		14.5 mA  133 hours (5 days)
Mode 3  51 lumens (medium 1)	134 mA   14 hours
Mode 4  149 lumens (medium 2)   430 mA   4.5 hours
Mode 5  344 lumens (high 1)     600 mA	 3.3 hours
Mode 6  672 lumens (high 2)     1.07 A   1.8 hours
Mode 7  1109 lumens (turbo)     2.48 A   48 minutes
Run times of course depend on what battery you use. The times above are based on a 2000 mAh battery. Note that I have not measured these times, I have measured the current draw and calculated the times.
