Yep, that's exactly what happens - it isn't until you fit a brand new one that you notice how dull they have become. I only noticed it because I had to replace a blown globe which had only been fitted about a month or so earlier (did two new globes at the time) and when I did I noticed the other "new" globe was heaps duller. I then did some back to back tests with both H1s and H3s in various driving lights and found it was common across all the Narva range. In fact in the driving lights (which when used are generally on for extended periods) the dulling was even more rapid than in the H4s.
