I run and sell those lights...minus their brand name on it. They are import LEDs that are simply bought and rebranded. I buy them direct from the manufacturer.
Their prices are not terrible really. A pair of their cubes are $136 and I sell them locally for $100....I have no overhead though.
As far as quality...they are great so far. Water and dust proof. Great construction.
As far as light output...insanely bright.
I have been testing different light bar mounts for the 50". I currently have the PSC mounts with Genright lower tabs welded on for Duallys.
I am waiting on a brand new set of mounts from another company (look for a review soon) that I think I am going to like better.
I also have a set of Genright windshield guards that I planned to add mounting tabs to, but have not had the chance to do so yet.
I have the 50", a pair of Duallys, and a 13" bar mounted on my TJ.
