Current range

While a rated current is specified for all LTI lamps, a current range is also specified. It is recommended that a lamp be operated at slightly less than its rated current at the beginning of its life, while being operated at the maximum range at the end of its life. The main purpose of this adjustment in current is to compensate for the slight loss of light that occurs with lamp age. It is not advisable, however, to continuously operate the lamp at minimum or maximum current, as the lamp’s performance and lifetime will be negatively affected.
