Terrarium lighting with neodymium gas. Neodymium gas provides a natural color spectrum and contains UVA radiation. It supports natural physiological processes with an ideal spectrum for plant photosynthesis. Additionally, it promotes reproduction and stimulates mutual attraction among animals. The REPTI PLANET Daylight Neodym bulb offers an optimal balance of ultraviolet UVA radiation, light radiation, and infrared (heat) radiation, making it ideal when combined with UVB and night lamps. This is a full-spectrum bulb that encourages physiological processes such as activity, food intake, and reproduction. Neodymium gas in a bulb can adjust the light spectrum to values that closely resemble natural conditions. It supports not only plant growth but also color perception. When selecting a bulb, it is important to consider not only the type of bulb but also the species of animal being bred and the distance of the animal from the heat radiation source.
