A system to illuminate fruit and/or vegetables in the food storage facility, comprising a lamp (8) and a controller (12). The lamp is operable to provide the illumination with a first light output and a second light output, the first light output having a higher intensity and at least a red-bias spectrum relative to the second light output. Further, the system comprises a controller for controlling the illumination of the fruit and/or vegetables in the food storage facility by controlling the lamp. The controller is configured to apply the illumination in a sequence comprising a period of darkness, followed by the first light output for a first period, then followed by the second light output for a second period.

Provided are methods of reducing and killing bacteria and fungi, and photodynamic treatment methods and sterilization methods using the methods of reducing and killing bacteria and fungi. The method of reducing and killing bacteria and fungi includes bringing a composition including a Ligularia fischeri extract or a fraction thereof as an active ingredient into contact with cells or tissues of a subject and irradiating cells or tissues of a subject in contact with the composition with an absorbable wavelength of excitation light.

A feedback system that identifies characteristics of an object and utilizes the characteristics to initiate and adjust a field applied to the object is provided. The system includes an array of array phase elements made of metamaterials that allow precise shaping of the field to be applied to a particular portion of an object based on characteristics of the object, including location and thickness of the object. Sensors are utilized during supercooling to monitor a condition of the object being supercooled. Specifically, characteristics of the object are measured at different points, areas, or volumes on the object and the measurements are used to determine whether supercooling (or another desired result) is being achieved or whether the object is starting to freeze. Based on the measurements, parameters of the field can be adjusted to ensure supercooling of the object without freezing.

A device that treats items containing chromophores with multiple wavelengths of light to provide a beneficial effect when the treated items are applied onto or within a user's body. The device may emit at least three different wavelengths that are selected from specific wavelength combinations that have been found to have synergistic and positive effects. Treating items with these wavelengths may increase the energy content of the items since the wavelengths may be absorbed by the chromophores, and specific types and levels of energy corresponding to the treatment wavelengths and chromophores may be radiated into a person's body when the items are used. Illustrative items that may be treated with light may include, for example, creams such as cosmetics, moisturizers, hair treatments, or pain treatments; pills such as pharmaceuticals, nutraceuticals, vitamins, or supplements; or drops such as eyedrops or ear drops.
