the colour, but will keep all the lamps slightly illuminated.
4) Leave the Spectre to cool before moving it. Filament lamps are
most vulnerable to failure just after switching off.
The expected lamp life at various settings of the dimmer are
shown below.
Setting Power Brightness Lamp Life
0% 0W 0% * *
25% 62.5W 1.5% * *
50% 150W 12.5% 204000 *
75% 320W 42% 1500 11000
100% 500W 100% 50 350
*At power settings this low, the lamp life will be determined by
other factors than the power consumed by the lamp, such as
switching on and off repeatedly, or mechanical damage. The
settings shown above have been chosen after extensive research
and testing to produce a control that appears linear to the eye.
Replacing the fuse
There is a small possibility that the fuse may blow when a lamp
fails. (This is caused by the filament of the failing lamp producing a
short circuit as it falls apart) The fuse is located in a drawer
beneath the mains input connector. Replace with another fuse
type F10A HBC. (10A Quick-blow, high breaking capacity
5x20mm) If the new fuse fails consult a dealer.
Cleaning
The Spectre should be cleaned periodically as dust will tend to
obstruct the fan, and impair the ventilation system. Clean the
dichroic filters with a soft lint-free cloth using alcohol or hi-fi
cleaning fluid
