If the bulbs are facing up, you might try dusting them. At least around
here, a coating accumulates. It's also true that bulbs are *brighter*
when quite new, tho that soon tapers off. And, as I recall, the rated
life of the bulb is circa 9 to 12,000 hours, no?

Plus, did you change anything in the vicinity? Reflection counts.
