MegaSun 2.0 Reptiles Planet bulbs emit a low level of UVB (for example: 20 W/cm² at 30 cm) and standard UVA (75 W/cm² at 30 cm). They are intended for animals with low UVB requirements such as amphibians, snakes, and all nocturnal animals (nocturnal geckos). This bulb, emitting a beautiful light (6700 K – CRI: 98), is sometimes used in combination with a Mega Sun 10.0. UVA provide physiological well-being to animals, helping to reduce stress, encourage feeding, and support reproduction. Mega Sun bulbs are therefore a real asset for breeding snakes and nocturnal geckos.
