9.9 Lamp
Lamp information light output switching
All information about the lamp is stored inside the lamp house and can be displayed via t
he projector software on the projection
screen. No information can be changed.
The Constant light output function can be changed between OFF, [slave] and [master].
By using the CLO function, the lamp life time will enlarge.
CLO for a single projector
When the CLO functions is in the OFF position, the lamp will follow the normal life cycle curve.
When the CLO function is ON (projector master or slave), the projector will regulate the lamp power until the preprogrammed CLO
value (number of lumens) (full line) is reached. As long as thi
s power is below the maximum power of the lamp, the projector will
gives a constant light output. Once the maximum power is reached, the projector will follow again the normal lamp life cycle curve.

CLO function of one projector
Linked CLO, used by multiple projectors
If the linked CLO function is in the OFF position, the lamp of each projector will follow its own life cycle curve (dotted lines). When in
the ON position and linked as described below, all projectors will use the preprogrammed CLO value as long as no projector in the
chain is using its maximum lamp power already. Once one projector is on its maximum lamp power (projector with the lowest light
output) all other projectors will follow from now on the life cycle curve of this projector. That means that light output will be constant
as long as no projector has reached its maximum lamp power. From then on, the light output of all projector will decrease (full line).
