I swear by these CF bulbs, not only are they much brighter than your standard CF, but they are coated with TiO2(titanium dioxide) which nutralizes odor, kills bacteria and mold, and even releases small amounts of CO2!!! I'm telling you these bulbs are the best CF lights I've ever used. I have four 42watt bulbs over 10 white widow plants. I don't even need an ionizer and my plants are so lush you would freak!!!
