I use nightbreakers in my van and the Croma had them already fitted when I bought it. The bulb life seems very good. In the past I have used cheap imitations and they didn't last very long, plus the light output was significantly less.
I have recently fitted Autobulbs Cobalt 2's, after reading some good reviews. They seem very good, though I can't comment on lifespan yet.
