This is a Sharp Plasma Cluster ion generator. It releases Plasma Cluster ions into the air, primarily providing "bactericidal and deodorizing" effects in small indoor spaces. Designed for air purification in confined spaces like toilets, it's installed by attaching it to a ceiling light socket, emitting ions from near the ceiling to suppress bacteria and odors in the air. It requires no construction and can be used like replacing a light bulb. It's a model with a human sensor, which detects people entering and leaving, enhancing deodorizing and bactericidal effects only when needed, and also has a function to link with LED lights. - Model Name: IG-011RA-H - Brand: SHARP - Light Color: E26 - Power Consumption: 485W - Included Accessories: Instruction manual, light bulb Negotiations for price reduction are not accepted.
