Overvolting shortens the bulb life but, in practice, it's not that big an issue. I've been over over-volting MR11s for years...either at 7.2V or 14.4V. I've only replaced one because of burn out. BatterySpace sells them for around $3 and they are of close to the same quality as OEM.
That said, I've read lots of raves about Jet Lites. Never seen one, however.
My systems are cobbled together from various stuff. Mostly around Niterider heads similar to the Trailrat.
