I haven't use that brand. More or less I've gone with Nokya and Hella. I get mine from Amazon. I had a set of Nokya Artic White 7000k halogen bulbs, Produced a nice white light, But doesn't compare to HID.
Look for some reviews on the Putco's they seem like quality to me, but can't be sure.
Yes I bought the 7000k nitro blue pures. It was after I got my halos which are h1's not h11's so I just put them in my fog lights. They light up the road good. I've tried to order h1's since April... They're still on back order so I gave up on the h1's and bought some Cruisin told me about.
