6700K bulbs are generally meant to simulate daylight as that is the color of the light we receive on Earth from the sun. You may think the sunlight outside is yellow, but it's actually blue.
Tungsten (incandescent) light is 3200K and is somewhat yellow. Warm white fluorescents are in this range too.
High pressure sodium lights (certain copper-colored street lights) have a Kelvin rating of around 2100K.
Cool White fluorescent bulbs are around 5000K.
Actinic bulbs are usually around 10000K and are meant for reefs because below the water at reef depth, most of the red light is gone and the light is very blue there. FW plants still get some red light because they're closer to the surface.
Remember, Kelvin ratings are NOT related to brightness, they are only a way to indicate the *color* of light. Lumens are used to indicate brightness.
While a 10000K bulb might look brighter, it may not do your plants much good because it's at the wrong wavelength.
