This is a Ford vs Chevy argument when you start talking about brand names.
I personally like Hamilton very much for thier equipment but I would be hard pressed to run thier brand bulbs as they rate among the worst in PAR value.
Such a strange 180* for a given company to have such nice quality equip and customer service but yet the bulb line is ranked just UNDER the 6 dollar no nam ebulbs from the crazy bidding site.
