Would they work for your application if you mounted them with the kind of flanges that came with TIR3s? The lightheads are physically the same size, but the LINZ6 flanges have a much larger footprint than TIR3 flanges.
I was gonna put them on my grill but the overall footprint an how thick the are looks kinda stupid so gonna go with a ion or maybe a feniex fusion. Something a bit more thinner in hopes they don't stand out terribly bad
