What version of software is in my flashlight? Hide answer...
Over the years, we have upgraded our software to improve the utility and reliability of our flashlights. Below you will find the edit history for all versions of the software that can be upgraded to the current version - starting with release 1.22 in March of 2010. Only significant changes are listed. Earlier versions of the software require earlier versions of the hardware that are not compatible with the current software.
Your light will tell you what version of software it is running. To retrieve this information, you start by performing a factory reset but you do not release the button until the light begins flashing - roughly 10 seconds after the light turns off and roughly 20 seconds after you pressed the button. Note that since you are performing a factory reset, you will loose any customizations your have made and will need to make the customizations again. Here is the procedure to determine the software version number:
If you are running 1.xx software, you will see a single number when the button is released and two numbers when the button is pressed. The two numbers are separated by a short pause and repeat after a longer pause. If you are running 2.xx software, the button is ignored and you will see three numbers separated by short pauses that repeat after a longer pause.
- Turn on your flashlight.
- Unscrew and open the battery compartment - your light will go out.
- Screw the battery compartment back onto the head. As you are doing this, the light will turn on dimly - this is the reset indication.
- Before the light turns off, press and hold the button. The light will become brighter when the button is pressed.
- After 10 seconds, the light will turn off. Do not release the button - continue holding the button down.
- After another 10 seconds, the light will begin to flash. You may now release the button.
- The flashes are grouped as 8 flashes with a pause separating them. Short flashes represent a 0 while longer flashes represent a 1. What you will be looking at are binary numbers. Write down the sequence of zeros and ones and use your favorite binary to decimal converter to convert the binary strings to decimal numbers.
- The numbers will continue to flash until you again unscrew and open the battery compartment.
The single number displayed with the button up has no useful value and should be ignored. The same is true for the first of the three numbers for versions prior to 2.2. The first of the three numbers starting with version 2.2 is the calibrated output divided by 10 and rounded to an integer. As an example, a 325 lumen light will have the value of 33.
The two numbers displayed with the button down or the second and third of the three numbers is the version number. The first number will be either a 1 or 2 and is the major version number. The second number is the minor version number. Version numbers are normally formatted as <major>.<minor> - e.g., 2.18.

Judging by the instructions, the luminous flux is indicated only from version 2.2. Apparently the only option is to ask Henry. I asked him recently, also about the golden dragon, he kindly answered me and gave full information about the version, lumens and production date.Still no way of knowing max lumen output I guess?

By the way, if you turn it on to the maximum level, does it go down a one level after 10 or after 40 seconds?
