Thread: WHY the oxymoronic descriptions of light bulbs?

    The sun only looks yellow to you because the sky is more blue, in contrast.

    Cool white today is just a carry-over of a marketing term from years ago that attempted to distinguish the fancy new coated light bulbs that looked more "white" in color than the older, uncoated counterparts. Now the term has stuck and the preferred type of LED light for use in most homes is 'cool white', even though the LED bulbs called "daylight" produce even more 'white". I happen to think that "daylight" bulbs work better in my shop than "cool white" because they are apparently brighter (wattage being equal). Now the more proper terms have to do with Kelvin ratings which nobody (most consumers) really understand.

    The kelvin rating is more an issue of brightness for most (including those who sell them commercially). It has virtually nothing to do with color.

    We have some 6500 and 8500 Kelvin fixture in the shop and outside fixtures and at 6500 youd better be prepared to see dead-white and spots in your eyes.

    Completely backwards.

    Color temp has everything to do with color and nothing to do with brightness.
