Terrarium lighting. Ideal for all tropical and subtropical reptiles. Low amount of UVB, tailored to the forest floor of the rainforest. Effective up to 30 cm (a minimum distance of 10 cm is recommended). Produces the necessary UVB rays for optimal calcium metabolism. Contains UVA rays that stimulate activity, appetite, and reproductive behavior. Repti Planet UVB 2.0 does not emit sufficient heat and light rays. Combine with heating and lighting lamps if necessary. The optimal UVB intensity radiation aids in the conversion of vitamin D3, ensuring calcium absorption. UVB radiation is a part of sunlight that is essential for the health of terrarium animals and helps prevent metabolic diseases. The intensity of UVB radiation in bulbs decreases during use.
