It has come to our attention that, in some instances, the lifetime of the MSD1200 lamp was unexpectedly short. In most cases this was due to AC mains voltage not complying with the actual mains voltage setting on the fixture. To reach optimum average lifetime from the lamp it is important, that the mains voltage never exceeds the value from the setting on the fixture at any time. To help selecting the right setting on the fixture for the voltage in your area, please refer to the scheme below. For information on how to set the voltage on the fixture refer to the user manual.
