Hollow Cathode Lamps
Photron provides the following warranty on it's products:
All Photron Hollow Cathode Lamps and the Super Lamppat. are warranted to be free of material and manufacturing defects when operated at the correct current for each instrument as detailed on the lamp operating data sheet supplied for each element.
The operational lifetime of all the above is rated 5000mA Hrs, based on the currents specified in the data sheet e.g. lamp run at 10mA last 500Hrs.
The use of currents higher than specified, particularly on instruments where high peak currents are used, will shorten the life of some elements. Those affected either have a high vapour pressure (Hg, As, Se) or high sputtering rate (Au, Cd, Zn).
Warranty claims regarding lamp failure will be considered for up to 2 years from the date of purchase. Warranty claims must accompany a completed warranty card. If a free replacement lamp is supplied the validity of guarantee shall date from the shipment of the first lamp.The shelf life of unused lamps are warranted for 5 years from the original purchase date. Any hollow cathode lamp found faulty before any use will be replaced.
Deuterium Lamps
Deuterium Lamps will maintain 1000Hrs at 300mA DC. These lamps should maintain more then 50% of initial intensity. Where lamps are used in pulsed systems with short duty cycle that have excessive peak currents >600mA, life will be less then the above.
Warranty is considered up to 1 year from purchase. Any replacements will date from the purchase of the original lamp.
