FS FireRay LED as bright as whelen M?

[got_yogurt]

Has anyone seen the fireray LED series in person and if so are they as bright as the whelen M series?

I think the M series are brighter. I would also be sure to enable the dim mode b/c they’re bright as F@#K at night (and sometimes too bright when multiple units are responding one behind the other)
