Solar LED lights are LED lights used mostly for outdoor lighting. These are used in conjunction with solar panels that capture sunlight and heat. Solar energy so captured is used to charge rechargeable batteries that supply power to LED lights. Some of these LED lights used for outdoor lighting have even a self-programmed on/off feature and, therefore, one need not purchase extra timers. These are convenient to use, energy efficient, easily portable and ideal for outdoor usage. Being energy efficient, areas can be kept lit for as long as 12 hours a day.
The LED Lighting industry is rapidly growing and all manner of light products are being produced with LEDs as standard. This makes factories compete to produce the most efficient and cost effective LEDs and naturally means the quality will improve. The efficiency and light output of LEDs have been doubling every 36 months since the 1960's a big part of this is due to general technological advancement in semiconductor technologies and in optics and material science.
