Which of the following is the most efficient form of lighting?
LED or light emitting diodes are most efficient for lighting purposes.
LED bulbs produce 90 to 112 lumens per watt, Compact Fluorescent Lamps produce 40 to 70 lumens per watt, and incandescent bulbs produce 10 to 17 lumens per watt. From this, you can see LED light bulbs are the most energy efficient.
LEDs generate relatively little heat, last 100 times longer than incandescent light bulbs, and convert more of their electrical energy to light. LEDs are the most efficient technology for conventional forms of lighting, such as home and office illumination, as well as streetlights.
Using full spectrum lighting has been shown to improve an incredible number of things, including our mood, productivity, mental awareness, color perception, visual clarity, sleep quality, sleep cycle, and our performance at work.
Energy efficient lighting involves in replacement (or re-lamping) of traditional lamps (such as incandescent lamps) with that of energy efficient such as fluorescent lamps, CFL lamps and LED lamps. It also incorporates proper lighting controls such as timer controls, PIR and ultrasonic sensors based controls, etc.
LED fixtures use 75-80 percent less electricity than incandescent bulbs, and can have a lifespan 25 times longer than incandescent light bulbs. 16 LEDs produce in the range of 27-150 lumens per watt, depending on the type of LED.
Incandescent Lighting
Incandescent lights should be turned off whenever they are not needed, because they are the least efficient type of lighting. 90% of the energy they use is given off as heat, and only about 10% results in light.
XED or Xenon Energy Saving Discharge Lamps are superior to the most popular LED or Light Emitting Diodes in many ways. XED lights are better in terms of spectral contents, power consumption as well as total running life hours. They produce less glares and are clearer under foggy weather.

Halogen bulbs are a type of incandescent that gives a close approximation of natural daylight, known as "white light." Colors appear sharper under halogen light and the bulbs can be dimmed. They're a little more energy efficient than incandescent bulbs, but they're more expensive and burn at a higher temperature.
What is the best type of indoor lighting?
Ambient, or general lighting, is needed in every room. It provides a comfortable overall level of light. Ambient light sources are typically overhead lighting, such as ceiling light fixtures, and as a general rule it's the best place to start when lighting a room.
