Brighter headlight bulbs question

Glad to see some others have converted. For as cheap as they are they are a great upgrade and well worth every penny.

Love the Osrams! Silstars only last less than a year on my metrics and Hd's

Silverstars never lasted me either, but they were the first bulbs to come to mind.

So if Silverstars don't last, what are a bulb that will last?

The Hella 80/100w bulb in my bike has been on the bike since new (almost four years) and was on my old RK for several years before that. I believe at least some of that longevity is attributable to the modulator that works at 20-100% 4x/sec., and this reduces heat, but before I bought the modulator in 2002 I was still not replacing them frequently. I don't think I've changed more than once or twice in the past 12 years since I started using them. The bulb-life spec is 100 hrs., but I'm obviously doing much better than that. Is anyone else having this level of longevity from these bulbs?

I've seen this spec and don't know how they've arrived at it. The bulb in my bike now has been in there since the bike was new and was in my old RK for several years before that. I've changed these bulbs 1-2 times in the past 12 years, but the last eight years I've been running a modulator, and they reportedly prolong bulb life in daylight when the high-beam is running because the bulb runs cooler (20-100% modulation @ 4x/sec.).
