Indoor lighting is a basic pan- light, as long as a certain brightness, the human eye can feel comfortable. The light source can not produce uncomfortable glare ( too much light reflected or light contrast  ) , led lamp including interior such as LED tube light and exterior LED light is a new type of green light，which is known as cold light source with less glare, no radiation, less harmful substances. LED’s operating voltage is low, adopting the DC drive, ultra-low power consumption, electro-optical power conversion is close to 15%，which saves more than 5% than that of traditional energy sources under the same lighting effects. LED’s environmental benefits is better, there is no ultraviolet and infrared in the spectra, and LED lights has recyclable waste, less pollution, no mercury elements, belonging to a new era of energy-saving green lighting therefore choosing appropriate LED light source，the LED downlights and LED tube light with frosted PC cover or hood are the best choice ，or LED bulbs with PC cover for the  directly lighting，make sure the  power (watts ) of LED tube light and LED bulb light source should not be too large, and in accordance with people’s habits ,  the color temperature of LED tube light and LED bulb or other interior LED lighting source must below 6000K .

The supermarket mainly use a small power LED lights: such as LED ceiling light, LED tube light or corn lights with screw cap and horn light are very good. But LED tube and LED ceiling light and LED downlight  with warm white  is mainly used at hotel，3 watts -7 watts is enough, such as the LED ceiling lamp 1.5W with warm white cup available installed in the room. Regardless of the degree of warmth from the energy and ideal lighting,we should particularly emphasis on that commercial lighting including LED tube light and LED ceiling can not blindly painted cheap, just quality LED tube light and LED ceiling and LED bulb or other interior LED light save money ( both power and long life ).Browsing http://www.ledclan.com/ for more information about interior LED light.

Although luminous efficiency of LED light especially high power LED light including high power LED flood light is higher, but just a small part of electricity flowing through the LED can be radiated in the form of visible light energy, most of the remaining energy is consumed in the form of heat in the LED, the LED light source particularly high power LED flood light and other power LED light has serious fever. there are following reasons for low reliability of   driver of  high power LED light and other power LED lights of LED industry:

First, close to a heat source.

LED drivers are usually placed inside the high power LED flood light and other LED packing light, which is close to the LED light source, the ambient temperature around the driver can easily reach 50-60 ℃only at 20-30 ℃ temperature environment, it is a great challenge to design ( especially efficiency indicators )  to ensure the drive reliability at such a high temperature environment.

Second, long-term work at full capacity .

The driver of high power LED flood light and other power LED light is close to full capacity without dimming, while the vast majority of applications in switching power supply, such as computer power supply ( adapter ), communication power supply, and household appliances, an average power of long-term work is usually only a fraction of rated power，all the loads turned on full power state only appears a few times in a particular .

Third, for high power LED flood light and other outdoor lighting applications on roads, squares, etc., they are vulnerable to external damage to natural phenomena such as lightning. All these will result in ongoing maintenance and other ills of large-scale application of high power LED flood light and other LED semiconductor lighting.

The high reliability of drive of high power LED flood light and other LED light is an important condition for product quality, but also is the urgent technical problems compromised .Browsing http://www.lead-lighting.com/products/sid125-1.htm for more information about high power LED flood light.
