It's not necessarily a requirement. I forget the exact type of bulbs we bought last, but they were a good 4-5x the price of the bulbs we used to get, and lasted just as long, if not a shorter duration of time.
I'm hoping not to find them so that I can show my boss they're no longer around, we can make an initial hefty investment to get all our lighting changed to the newer light bulbs that will last us years, instead of 30-40 days.
