When it's bright, clear, defined task lighting that you need, these 100w daylight bulbs from GE will surely fit your need. With a color spectrum rating of 6500 kelvin, equivalent to daylight spectrum, these bulbs earn the Daylight nomenclature on the packaging. As a point of reference most standard CFLs only have a 2700 kelvin rating, well under half the kelvin rating that this premium bulb provides. Cool natural lighting, the GE way.
