There are many led light bulb in the led lighting market, in order to choose a a perfect light bulb,you should know the characteristic of them.
1.Compact Fluorescent Light Bulbs: Compact fluorescent is a generic term used for a variety of bulbs. CFL's use 20-40% less energy to produce more light per watt and are color adjusted to produce light close to real sunlight. CFL's generate less heat and offer a longer life than incandescent bulbs, saving you money on electric bills and protecting the environment from harmful greenhouse gas emissions. Look for Energy Star labels on fluorescent fixtures and lamps for assurance of maximum savings, quality and standards.
Compact fluorescent light bulbs are commonly used in desk lamps, floor lamps, under cabinet lamps, table lamps, linear strips, wall sconces, flush mounts, chandeliers, close-to-ceiling or flush mounts, pendants, ceiling clouds, kitchen island lights, path lights, outdoor wall lanterns, outdoor post lanterns, as well as outdoor wall and ceiling mounts.

3.Halogen Lamp Light Bulbs: Many of today's lamps use Halogen light bulbs. Halogen bulbs produce a whiter light and produce more light (lumens) per watt than standard incandescent bulbs. They most closely replicate the color spectrum of the sun. Their small size and intensity make halogens great for task lighting.
For precise and controlled beams of light, low voltage halogen bulbs are specified for dramatic effect in highlighting details with pinpoint beams of light on artwork, architectural details, sculptures, etc. Low voltage bulbs are 12 or 24 volt and require a transformer.
4. Xenon Light Bulbs:
Xenon light bulbs are made from Xenon, a rare gas used in specialized lamps. They are known to last up to 10,000 hours. Xenon bulbs can be touched with a bare hand unlike halogen bulbs.
Xenon light bulbs are commonly used in path lighting.
