The Titan Tube is leaving the Astera factory in a special ship mode that allows it to be stored
for a long time without damaging the battery. When using a Titan Tube for the first time,
connect it to AC power for a few seconds to exit the ship mode. Otherwise it cannot be
turned on.

The lights work with a specially optimized RGB color space, the AsteraRGB color space. It is
designed to eliminate the need to control each color individually to display a certain color.
Instead, the light calculates the optimum combination of all colors based on an RGB value. It
considers each LED chip’s temperature as well as an optimal color
rendering.
Due to this, it is possible to reproduce colors with high accuracy. It is possible to calculate an
AsteraRGB representation for any CIE color. The easiest way to do this is with the AsteraApp™:
•
Go to the color picker and add a new favorite color
•
Go to favorite colors and edit it
The dialog on the right will open.
It allows you to find AsteraRGB values for a certain color
temperature. S-RGB or CIE1931 values can be calculated to
AsteraRGB by pressing the corresponding buttons.
The primaries of the AsteraRGB are defined as:
White Point
x
y
0.4917
0.4878
The light also includes the Dynamic Powerboost feature. It ensures that colors that consume
less electrical power are boosted slightly, while power-consuming colors are slightly
compressed. This maximizes the brightness while maintaining the desired battery runtime.
While controlling with the AsteraApp
™
or by the Control Panel, only RGB values can be set.
By DMX control, it is possible to control the Amber LEDs separately and also to emulate white
channels. But it should be noted, that then temperature compensation is only available for
Red, Green and Blue; all other colors will experience temperature drift, their brightness will not
be constant.
