Question Halogen lamp testing

I have a halogen floodlamp fixture that i keep putting bulbs into every day. The bulbs seem to blow every hour. I have checked the wiring (this is a simple 120v. line voltage fixture, mounted outside) and was wondering what could be blowing these bulbs. The only idea i had was the bulbs that i am using are ge 75 watt par38 and i bought them in a big case of about 25 or so at a local lighting store. Maybe i got a bad batch of bulbs? I test the lamp resistance and my Fluke scopemeter or true RMS multimeter all say infinite ohms. What is wrong????

Wow, this is odd.

Are you careful not to ever touch the bulb with your bare skin (a must for halogen bulbs)?

Is the fixture subject to vibration?

I suppose you could have a bad batch. Buy one more individual bulb at a different store to test that theory.
