They are much brighter than GPs. GPs are great for color and nighttime, bad for daytime. But I don't think my CVs are as bright as some pics of the LUX I've seen. Personal preference here, I honestly like mine better as it looks like a "natural / oem" xenon color that would come on the car, those LUX are way too blue and too bright for me. Just my take, to each their own. I will work on the pics, but I live in OK and we just got what's left of hurricane Hermine so it will be overcast for a while here.
