outdoor led lightingA lot of activities that happen at night require powerful lighting, such as construction. If you want to throw a fabulous party outdoors, powerful and decorative lighting is indispensable. And definitely, you don’t want to be bothered by worms and bugs. But that’s what will happen with powerful light at night, especially in the summer. Well, that’s the case of traditional lights. Outdoor LED lighting can shelter us from this annoying situation. In fact, outdoor LED lighting has many advantages.
Advantages
•    Efficiency: LEDs emit more lumens per watt than incandescent light bulbs.
•    Color: LEDs can emit light of an intended color without using any color filters as traditional lighting methods need. This is more efficient and can lower initial costs.
•    Size: LEDs can be very small (smaller than 2 mm2) and are easily attached to printed circuit boards.
•    On/Off time: LEDs light up very quickly. A typical red indicator LED will achieve full brightness in under a microsecond. LEDs used in communications devices can have even faster response times.
•    Cycling: LEDs are ideal for uses subject to frequent on-off cycling, unlike fluorescent lamps that fail faster when cycled often.
•    Dimming: LEDs can very easily be dimmed either by pulse-width modulation or lowering the forward current. This pulse-width modulation is why LED lights viewed on camera, particularly headlights on cars, appear to be flashing or flickering. This is a type of stroboscopic effect.
•    Cool light: In contrast to most light sources, LEDs radiate very little heat in the form of infra red that can cause damage to sensitive objects or fabrics. Wasted energy is dispersed as heat through the base of the LED.
•    Slow failure: LEDs mostly fail by dimming over time, rather than the abrupt failure of incandescent bulbs.

Fluorescent tubes typically are rated at about 10,000 to 15,000 hours, depending partly on the conditions of use, and incandescent light bulbs at 1,000 to 2,000 hours. Several department of energy demonstrations have shown that reduced maintenance costs from this extended lifetime, rather than energy savings, is the primary factor in determining the payback period for an LED product.
•    Shock resistance: LEDs, being solid-state components, are difficult to damage with external shock, unlike fluorescent and incandescent bulbs, which are fragile.
•    Focus: The solid package of the LED can be designed to focus its light. Incandescent and fluorescent sources often require an external reflector to collect light and direct it in a usable manner. For larger LED packages total internal reflection (TIR) lenses are often used to the same effect. However, when large quantities of light are needed many light sources are usually deployed, which are difficult to focus or collimate towards the same target.
Outdoor LED lighting can be used in many places, from household porch, yard to football stadiums, parking lots. This kind of light enables you to get powerful brightness for night activities while also relieves your worry about electrical cost. With so many advantages, outdoor LED lighting is going to reform the lighting world.
