*[Paraphrased derived summary — non-Open-Access source.]* Leopard geckos are terrestrial arid-scrub lizards; recommended 25–30°C (77–86°F) at 20–30% relative humidity. *[Paraphrased derived summary — non-Open-Access source.]* UVB light (290–300 nm) is especially important for most day-active lizards and chelonians for vitamin D3 synthesis and calcium regulation. *[Paraphrased derived summary — non-Open-Access source.]* All reptiles, including nocturnal and crepuscular species, benefit from broad-spectrum lighting; unfiltered sunlight is best, with artificial UVB bulbs as a useful alternative. *[Paraphrased derived summary — non-Open-Access source.]* Humid microclimates are often critical for arid species (e.g. tortoises, leopard geckos) to reduce shell pyramiding and abnormal sheds.
