Yes. Green iguanas are daytime basking reptiles and require appropriate UVB exposure in captivity. UVB helps support vitamin D3 production and normal calcium metabolism.
Does sunlight through a window provide UVB?
No. Glass and plastic block useful UVB. Indoor iguanas need an appropriate reptile UVB source unless they are receiving suitable direct, unfiltered natural sunlight in a safe outdoor setup.
What UVB bulb should I use?
Green iguanas have relatively high UVB requirements. Choose a quality UVB system intended for high-UVB basking reptiles. Exact lamp strength and placement depend on the fixture, reflector, screen or mesh, and manufacturer instructions.
Does UVB replace a basking lamp?
No. Iguanas also need a thermal gradient and basking heat. Heat and UVB are separate husbandry requirements even when a particular lamp system provides both.
