Doshisha Unveils the Latest Luminasave LED Ceiling Light

In an exciting development for home lighting solutions, Doshisha Co., Ltd., based in Osaka, Japan, has announced the launch of their latest product, the Luminasave 20-tatami Adjustable and Color Changeable Model. This state-of-the-art LED ceiling light will be available starting mid-May 2026. Thanks to its impressive luminosity of 14,000 lumens, this product recently topped the brightness rankings for LED ceiling lights aimed at general household use, as per a market survey conducted in May 2026 by the Japan Marketing Research Organization.

Overview of the Survey

The market survey, which took place from May 20 to May 29, 2026, focused on 20-tatami LED ceiling lights, evaluating offerings from 11 leading companies in this sector. This investigation employed a detailed methodology that integrated public information with insights obtained via interviews with industry professionals, although the figures may vary from actual results. It should be noted that this information is indicative and does not guarantee efficacy or superiority at this time.

Background of Product Development

The recent regulations regarding mercury, which mandate the end of fluorescent bulb production and imports in Japan by the end of 2027, have profoundly impacted the lighting industry. This impending shift has created an urgent demand to convert old fluorescent lights to energy-efficient LED alternatives. In response, Doshisha decided to upgrade the existing model of their 20-tatami LED ceiling light (E55-W20DS) to this new enhanced version, designed to illuminate larger spaces effectively.

Key Features

• - Unmatched Brightness: The Luminasave model achieves a groundbreaking total luminous flux of 14,000 lumens, effectively brightening even the corners of spacious living rooms, ensuring uniform illumination throughout.
• - Energy Efficiency: This new model boasts top-tier energy-saving capabilities, allowing users to save 58% on energy bills compared to using fluorescent lamps for a 20-tatami room. Users previously faced costs of approximately 11,656 yen annually on fluorescent lighting, which can now be reduced to just 4,817 yen per year with this new LED option. This is based on projected usage of 2,000 hours a year at a rate of 31 yen per kWh.
• - User-Friendly Remote Control: The product includes an LCD remote that facilitates adjusting light brightness and color, and it comes equipped with convenient settings such as 'night light', 'sleep timer', and 'absence timer', all visible at a glance.
• - Easy Installation: With a design that simplifies matching the installation points, setting up the ceiling light is a breezy process, allowing for a smoother installation experience.
