A system to control the conditions of an aging room, also known as a conditioned space, for products in which independent feedback loops control the dry bulb temperature and the dew point while controlling the difference between the vapor pressure in the room and the vapor pressure of the products being dried, thereby controlling the amount of and rate of water or water vapor loss of the products and, therefore controlling its quality, the system also including target controls, a thermoelectric cooler and lighting controls.

The invention provides a method of selecting the suitability of a lighting device (100) for use in cheese lighting, the method comprising (a) defining a normalization factor (k) for a spectral power distribution (SPD()) of lighting device light (101) of said lighting device (100) in a wavelength range of 380-780 nm, (b) defining the lighting device (100) suitable for use in cheese lighting when a cheese damage function value (CDFV) is equal to or below 2, wherein the cheese damage function value (CDFV) is defined as: (I) wherein: (II) wherein y () is a 2-degree color matching function, and wherein DF()=1 for 380 nm<410, and wherein for 410780: (III).
