Electrical connection

Clean and inspect electrical connections periodically. A layer of oxidation can build up as a result of lamp heating and cooling, ultimately leading to overheating and failure. Also, electrical connections endure severe strains as a result of high current and temperature; periodic inspection thus reduces the possibility of damage.

Mercury xenon lamps are best operated between 85% to 110% of rated power. New lamps should be operated at 85% power, and as the lifetime progresses, power may be increased until the maximum 110% of rated power is achieved. Replace lamps that do not provide sufficient output at the maximum rated power.
