When the need for LCD flat panel displays chooses back lighting lighting, designers often face should use white led with a pure white light or the RGB light source of the dilemma. White led drive and RGB drive is different, for example, used for portable electronic devices in the display, or general back lighting lighting applications to drive the highly RGB led of have no low inductance low noise led drive IC, and standard white led drive IC have different performance standards, this is because RGB led and white led toward the voltage is different, so need different IC architecture. Usually RGB led strip lighting will have a coil of ON/OFF interface and 3 separate resistance can be programmed to control LED current source dimmer and brightness, in addition, it will adopt the "white" mode to optimize red and green and blue LED the current ratio, so, in all three RGB LED programming for when to obtain the best ON the spectrum of.To provide for the display back lighting cold cathode fluorescent lighting (CCFL) has a limited chromatography, and colour bright enough. RGB LED actually expanded the scope of visible light. In addition, in the national television systems committee (NTSC) of the definition of the colors, CCFL shows about 80%, and can be a show of RGB NTSC chromatographic up to 110%, so the screen can show the beauty of image more accurate. Three monochromatic light source, such as red, green and blue (RGB) laser, will get the possibility is the most extensive chromatography. The number of "Bands of Frequencies" used is of significant importance to photosynthetic activity. There are 3 photosynthetic processes that occur; Chlorophyll A, Chlorophyll B & Carotenoids. To address these processes you would need a minimum of 3 Bands, and to bring the full potential of your plants photosynthetic ability, you will need 2 of these Bands to be duplicated in more than on spectral output.This is why we use 5 Bands in our lights, any more would be redundant and done so with an off-peak frequency. Some companies advertise as much as 10 or 11 Bands, and although this sounds good in theory, in reality it is using the same principles that make an HPS light only capable of emitting 15% of absorbable light to your plants and this defeats the whole efficiency concept behind the use of LEDs.Lastly, the choice of which company to purchase your LED Grow Light is ultimately up to you and we try to provide you with as much detailed information as we can to help you make a more informed decision. To better ensure you are getting what you pay for, make sure the company has been in business for several years and they offer a guarantee of performance and stand behind the product they are selling to the public. The best way to really determine if you're buying a quality light is to talk to the company and ask questions.
