Battery Warnings
When powered ON,
the GL-1 can be
dimmed 2 ways.
1.
On the fly, by squeezing
the spring-loaded trigger, to find and
temporarily hold at the desired output
level setting.
2. For longer term lighting
where you want to set the dimming level
and leave it, first squeeze the trigger all
the way in to lock it. Once this is done,
GL-1's level can be adjusted using the
dimming Intensity Wheel on the back
at the top of the handle. This level stays
even if the unit's power switch is turned
off. Squeeze trigger again to release
the lock.

fresnel lens as for adding color chang-
ing filters, such as an 82B tungsten to

You can also add an 82 mm lens shade
to help prevent direct light spills into
the camera lens during timelapse light
painting situations.
