Panasonic Electric Works has released a white LED lighting fixture with a brightness of about 1.4 times and a luminous flux of 900 lm, "LED ceiling lamp with new MFORCE". When set on a ceiling of 3m high, the illumination of the floor reaches 500lx or more, and the illumination of the floor up to 1m (ie, 2m below the ceiling) is 800lx. According to the JIS illumination standard of lighting brightness, the product can ensure the brightness required in offices, clinics, conference rooms, elevator halls and escalators. As a general illumination, white LED lighting fixtures are widely used. It is estimated that when using multiple lighting fixtures to achieve the same brightness in the same space, the power consumption of the product is only about 1/5 of the 100W incandescent lamp and about 4/5 of the 25W spherical fluorescent lamp. Scheduled for the fall of 2008. The sales target for 2008 is 5,000.

A luminous flux of 900 lm can be obtained by inputting 17.5 W of electric energy to the lighting fixture. Therefore, the luminous efficiency (combined efficiency) of the entire lighting fixture is about 51 lm/W, which is the highest level in the industry for indoor ceiling lamps and chandeliers. When the same power was input, Matsushita Electric's products were released in October 2006 at 460 lm, and in April 2008, the products were 660 lm.

The illuminating colors are available in plain white and bulb colors. The size of the lighting fixture is only 165 mm in diameter and 10 mm in thickness. Equipped with 8 high power white LEDs. Life expectancy is guaranteed to reach 40,000 hours. If you use 12 to 16 hours a day and 4,000 hours of lighting per year, you don't need to change the fixtures for nearly 10 years. ( Original link)
