The PAR specification given is fairly typical for this class of lamp. Notice the "Q" in the Order Abbreviation. This indicates that it is a Quartz Halogen incandescent lamp and it will have a much higher operating temperature than a standard incandescent lamp.
Also, they list an average life of 4000 hours. This is typical for this class of lamp so for your's to burn out so quickly indicates either a manufacturing quality control problem OR an overheating issue with your application.
Can you give us the make and model of your PAR cans? Do you have a spec sheet for them that indicates what lamps they are rated for?
Finally, as an interesting side note, they list the Color Temperature as 2950 K. This is below the photo/video balanced temperature of 3200 K. and is the clue as to how the manufacturer can rate the lamp at 4000 hours. There is no free lunch. To gain in one area another has to give. For example, a 1000PAR64Q/MFL with 4000 hours ave. life also has a color temp of 2950 K but the FFR (1000 W, PAR64 quartz) with 3200K color temp rating only has an ave. life of 300 hours!
