Rom to get closer to the wide range of incandescent light, three-dimensional configuration of LED. Therefore, in addition to downlight, also convenient for ball pendant.

The diameter of the luminaire is 55mm, height is 110mm, weight 120g. Day light color (color temperature 7000K), day white (with 5400K) and bulb color (with the 2760K) 3, just below the illumination were 52lx, 45lx and 37lx. Daylight color power consumption of 7W, brightness and 40W incandescent same. Price and sales methods, such as undetermined, the company spokesman said, will be compared with the price of competitive products, as far as possible in 2009 listing".
