I haven't found the ChromaQ ballast to be that noisy. Certainly is a lot quieter than my old TMB PowerPars. The fan can get noisy if things get really hot as it's variable speed, but as long as your fan isn't malfunctioning it isn't too loud.
Havent' compared the UV-block bulbs in brightness, but the light is certainly still super bright with them. Perhaps the UV blocking is especially aggressive and blocks a bit of visible spectrum too, or maybe light with UV looks/meters brighter because UV and violet spectrum transition is somewhat soft. I don't know a ton about UV but maybe it's like IR and there is some far Violet range that is affected by the filtration. Any kind of filtration tends not to be perfect, it may not be possible to perfectly target harmful UV for filtration.
