New types of light bubs are coming and that just uses LEDs. (Light Emitting Diodes)
Types of LED Bulbs
Currently there are 3types of LED light bulbs, as in the following figures:
Simple LED Light Bulbs
These type are formed of hundreds of LEDs. Can be of any color. The disadvantage is that the LED lights normally travels straight and without some kind of reflection surface, you cannot use it for common use.
Frosted LED Light Bulbs.
To overcome the disadvantage of Simple LED Bulbs, the coverings of these bulbs have some form of reflections to spread the light in all directions. This will be most popular form on LED light bulbs in future.
3D LED Light Bulbs
These type has special covering that will reflect the light in all directions.
At the moment, the prices are high for these types of bulbs. ( Ranging from $50 – $150 as type changes ). When more people realize their enery efficiency and start buying, I’m sure it will be in range of todays CFL prices.
