DIC Corporation announced that it would present its RADilys® fresh-flower illumination system to the public at Yokohama Takashimaya. The announced dates were October 14 through 20 and have now passed. This article summarizes DIC’s announcement; it is not an independently verified on-site report.
What DIC announced
According to DIC, RADilys uses fresh flowers treated with a proprietary coloring liquid and blacklight to create a luminous effect in darkness. DIC describes the result as “light emission”; under blacklight, it is a fluorescent expression. The company uses the concept “a flower blooms twice” to describe flower-derived colors in normal lighting and a different luminous expression in darkness.
The flower does not generate light by itself
DIC does not describe RADilys as genetically modified light emission. It presents the technology as a display system combining treated fresh flowers with blacklight.
Why it may matter to the flower trade
The same flower can be presented differently in light and darkness, suggesting possible uses for evening events, weddings, stages, and retail displays. These are editorially identified possibilities, not evidence of established demand, price, vase life, or distribution impact.
What businesses should confirm
- Compatible flower types and quality conditions
- Vase life and care after treatment
- Costs for lighting and presentation hardware
- Safety information and disposal guidance for the coloring liquid
DIC says it is targeting commercialization in the second half of 2027. The reviewed official pages do not provide a consumer sales date, price, or purchasing method.
