Light where you need it

Incandescents and CFLs waste at least 20 to 50% of light because their light distribution covers a 360° angle. The effective light is only a fraction of the total illumination. LEDs on the other hand offer double the glow in the same wattage as they produce directional lighting and focused illumination.
LED lights are directional in nature and they point out a steady beam of direct light to the area where the light is directed. A standard incandescent or CFL bulb electrifies a metal filament to produce light and therefore the lighting is distributed in all directions. Incandescents and CFLs have to be modified with reflectors and hoods to aim in a particular direction. But LEDs inherently produce a directional cone of light, which comes out from the top of the tiny metal pit inside the LED lamp. It concentrates light on one spot, so you get light exactly where you need it!

LEDs throw light in a measurable direction and the average glow of light is at an angle of 120° instead of 360°. LEDs can also be made to shoot out light in different angles such as 15°, 30°, 45°, 120° or 180°. LEDs are often mounted on flat surfaces to save light which is otherwise wasted by lighting up a ceiling. LEDs have higher luminous efficacy because they don’t need efficiency sucking reflectors or special optics to make light directional, in fact all the light can be directed towards the ground.
Due to their directional nature, LEDs can be crafted into unique designs to serve various functions. In art galleries, LED directional lighting can be employed to highlight exhibits or paintings. LED lights could also serve quite well for spotlighting and are therefore ideal for stage lighting. Interior task lighting, such as lighting up inside kitchen cabinets or specific work areas in the kitchen, can be an effective application of LED lights. Due to their small size and longevity, they are the ultimate choice for torchlight and accent lighting as well.
In homes, LED lights can be used in recessed lightings or to highlight specific areas of rooms, to become an integral part of interior design. LED lights are the ideal replacement for stairway and hallways lights where the focus in not on spreading light all over the place, but to lead a concentrated path. In outdoor lighting too, LEDs can be perfect for highlighting garden areas, walkways, yards, night lights and entertainment decks, due to their directional nature.

LEDs are also being used for lighting up fish tanks as they are cool, infra red free and they don’t reflect back out of the tank toward the eyes. As LED lights point in one direction, they can be ideal for replacing the hot and yellow light of reading lamps. LED lights generate a perfect beam of light and can replace the headlights of automobiles too. LED lights emit a pleasing white light with a bluish tinge, unlike fluorescent and halogen lights, which are harsh to the eyes.
Even if general broad lighting is used to illuminate a room, directional lighting is also required for reading, working and highlighting purposes. Due to their focused beam and energy efficiency, LED lights are the best option in directional lights.
