may be assigned to any setting. Your light has 20 brightness levels and the brightness
levels are referred to as brightness level 1 through 20, with brightness level 1 being the
brightest and brightness level 20 being the dimmest.
Note: you may notice a slight flicker on the very low brightness levels. This is normal.
Your eyes respond to light in a logarithmic way. That means that a significant increase
in brightness requires a doubling in the amount of light - and power. The brightness
levels on your light are spaced to provide small, visually even changes in brightness.
As a rough approximation, every two levels brighter will halve the battery life and
every two levels dimmer will double the battery life. You can maximize battery life by
using the minimum brightness level compatible with the task you are performing. The
lowest brightness setting will help preserve your night vision adaptation without using
a red filter.
The Brightness Menu adjusts the brightness level of the turn-on setting - that is, the
setting used when the light is turned on. By default, the Force Setting option from the
Options Menu is enabled and forces your light to turn on to the Primary setting. In
order to change the other three settings, you must disable the Force Setting option.
To set the brightness level of a setting, start by setting your light to turn on to the
setting you want to change. This is done by turning your light on, selecting the desired
setting and turning your light off. You may need to turn off the Force Setting option
from the Options Menu if it is enabled. As a double-check, turn your light on, verify
your light comes on to the setting you want to change and then turn your light off.
Now enter the Brightness Menu and select the desired brightness level. Once you have
finished setting the brightness level, you may re-enable the Force Setting option if
desired.
You enter the Brightness Menu by 10-click-pressing the button while your light is
turned off. Your light toggles on and off while you are clicking but this is normal. If
you don’t want to count, just keep clicking until your light stays on prior to doing the
final press.
Your light comes on to the currently selected brightness level when you enter the
Brightness Menu. Click the button to sequence through the brightness levels. Double-
click to reverse the sequence and move to the previous brightness. Note that the
sequence automatically reverses when you come to the brightest and dimmest
brightness levels.
