Intensity Wheel
GL-1 is a focusing LED fixture with
a ratio of 5:1, spot to flood.
To focus the unit, grasp the front of
lighthead and slide it forward to spot,
or backward to flood the beam.
As you slide the lamphead
forward, you will see markings on the
side of the focus barrel that will give
reference points to help
quickly reset the light to a
previous focus setting.
The markings do not
have any direct numerical
correlation to focus or output
settings, they are for visual
reference.
When powered ON,
the GL-1 can be
dimmed 2 ways.
On the fly, by squeezing
1.
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.
82mm Accessory Screw Thread
The screw thread on the front of GL-1's
fresnel lens as for adding color changing filters, such as an 82B tungsten to
daylight filter for lighting in daylight
color conditions.
You can also add an 82 mm lens shade
to help prevent direct light spills into
the camera lens during timelapse light
painting situations.
