The light spectrum emitted by the sun, particularly the visible light spectrum, emits light in seven different colors (red, orange, yellow, green, blue, indigo, violet). Colors on the far ends of this spectrum play a key role in the health and propagation of plants.
Standard incandescent light bulbs output light that's around 2500K in color, which is soft and just slightly yellow. The warmest LED lights I've been able to find are 2700K, and that's a perfect color temp for nearly all interior spaces in a residence (bedrooms, kitchens, bathrooms, living areas, etc.).
CFL bulbs come in many shapes and sizes, including traditional, globe, candelabra, flood and triple tube shapes, but the most common is the spiral bulb. They also come in three different base types: screw in, plug in and GU24, which is a recent addition to the type spectrum for CFL bulbs.

The color of the red birch is a bit darker, but really not that much. Yellow birch is only off of white by a shade. They're pretty darn close.
In big grow operations in the US where indoor space is very limited, some growers opt to use several 1000W grow lights, as even plants along the edges get strong amounts of light, and this reduces the total number of grow lights to adjust up and down as rows of plants grow taller.
Chlorophyll in the plant is the pigment that absorbs light. Light is made up of three different colors: red, blue and green. The reason that green plants appear that color is that they reflect that color in the light spectrum. In other words, the chlorophyll in the plant absorbs the red and blue light much more readily than the green light.
Actinic = Actinic light comes from the blue end of the color spectrum and this type of light is better for penetrating deep water than traditional white light. For this reason, actinic light is often recommended for large saltwater tanks.
Exposure to the light of white LED bulbs, it turns out, suppresses melatonin 5 times more than exposure to the light of high pressure sodium bulbs that give off an orange-yellow light.
Pros: Produces a highly concentrated light that is best for "spot" lighting for close work tasks such as reading and sewing. Light is very stable (no fluorescent "flicker") and can be easily controlled with a rheostat or dimmer switch.
