【Features】 ● In addition to "Widespread High Luminosity," which spreads light with a lens, "Wide Light" is added to illuminate even the corners of ceilings and walls. Hitachi's unique two technologies spread light throughout the room and soften the contrast in the room, expanding the sense of space. In addition, 120 new LEDs are installed on the upper part of the ceiling. This new LED ceiling light provides bright illumination even in places that were previously difficult to reach, such as sofas and shelves near the walls, supporting a convenient and comfortable life. ● Pressing the "Easy View" button increases the brightness of the daylight and incandescent LEDs to 1.2 times the full light, and the "Easy View" LED lights up to add blue-green light. This creates even brighter, more natural light that is closer to sunlight. The clear light color enhances the contrast, making fine text clearer and colors in photos appear more vivid. ● You can also enjoy your own lighting by adjusting and memorizing the brightness and light color of the light to your liking with the four buttons of "Light Select." You can also activate "Wide Light" in conjunction with "Light Select." You can select recommended lighting that combines brightness and light color for various living scenes with the touch of a button. ● Simply pressing the "eco-this-much" button allows the sensor to detect the brightness of the room and maintain the pre-set room brightness. It automatically dims when there is sufficient brightness from external light. It is an energy-saving function that automatically turns off when the brightness exceeds the set brightness. ● Easy maintenance. ・ The cover uses a material that does not easily attract dust and dirt. You can lightly dust it off with a dry, soft cloth. ・ It contains almost no ultraviolet rays that insects are attracted to, so insects are less likely to gather compared to fluorescent lights, and the gap between the main body and the cover is reduced with a packing, making it a structure that prevents insects from entering. 【Specifications】 ● Applicable tatami mats: ~8 tatami mats ● Light color: Incandescent (2700K) ~ Daylight (6500K) ● Outer diameter dimensions (mm): Width φ700 x Height 128 ● Mass (kg): 4.7 ● Rated luminous flux (lm): 4299 ● Rated power consumption (W): 31.2 ● Specific energy consumption efficiency (lm/W): 137.7 ● Power consumption (W) when using "Wide Light" and "Easy View": 55 ● Material: Cover (milky white acrylic) ● Cover removal: Rotary type ● Timer remote control switch included (IR-A05HST) / with wall-mount holder
