Used in corridors and stairways of older buildings (“tong lau”), Lumix aims to improve public conditions by functioning as a 3-in-1 product: an LED light bulb with water-coating to illuminate the dark surroundings, perfume or dried flowers to alleviate the nauseous smell, and a sanitizer auto-sprayer to prevent contamination and disease from spreading. Through our device, a more hygienic and attractive environment is furnished.
