These 4-pin tri-phosphor circline fluorescent lamps are all "warm white", with rated lives of 10,000 hours. Realize that fluorescent lamps are ballast specific, so if the MaxLite fixture has a ballast designed for a 30 watt circline it is not possible to install a different wattage lamp to get more or less light output. For indoor use only.
