CITIZEN pointed out that the company's previous CL-L102-C3N series LED products are suitable for LED light sources used in electronic devices such as mobile phones, with a luminous efficiency of 70 lumens per watt, and a maximum light volume of 245 lumens. It has been adopted by many manufacturers in Japan and internationally. The CL-L102-C7 developed this time has better product specifications and efficiency than previous works. It is an improved CL-L102-C3 series with more than twice the amount of light.
Due to the improved luminous efficiency, CITIZEN believes that the CL-L102-C7 can replace the 40-watt bulb-white bulb and the 8-watt bulb-colored fluorescent lamp. It is also a good choice with solar cells. Because the CL-L102-C7 can reduce the input voltage to 160 milliamperes (mA) in power-down mode, it produces up to 150 lumens of light at 110 lumens per watt.
CITIZEN pointed out that the CL-L102-C7 also introduced a product with a color temperature value of 2,900K. It is expected that the product will be delivered in October 2007, and will be officially mass-produced and shipped in January 2008.
