Before getting an iguana, there are several things you need to seriously learn about, and lighting in iguana cage is one of these. Do you know how to supply their basic lighting needs?
You either are looking to get the bulbs to light up for a new iguana enclosure, or you might be having trouble finding the right lighting bulbs to keep your iguana warm, stay healthy in a large habitat. A variety of lights in Iguana cage are needed, some for heat, some for white light and some for UVB light.
#1 Visible light
Apart from heat production, Iguanas also need incandescent bulbs to be provided visible white light. Iguanas are actually quite fast and agile on land, they need white light to look for food and move around. You can use both fluorescent and incandescent light fixtures at the same time to provide visible light to all areas of the enclosure.
#2 UVB light
One of the most important aspects when keeping Iguanas is provide them enough amount of UVB in enclosure. They need a certain spectrum of ultraviolet to synthesize vitamin D3, which is needed to help metabolize calcium in the Iguana’s diet. This is because Iguanas cannot process dietary D3 themselves.
There are reptile specific UVB bulbs on the market, and those are the ones you should be looking out for. linear fluorescent bulbs, Mercury vapor bulbs, and compact fluorescent bulbs are best UVB light for Iguanas that you should consider. There are also some types of lights that producing only UVB, and lights which produce a combination of UVB and white lights are available.
Be careful when shopping for a UVB bulb. Many brands commit that their bulbs are full spectrum, but they may do not produce UVB. Remember that fish/aquarium and plant grow lights, either incandescent or fluorescent, do not produce UVB. You need the UVB light that specific designed for reptiles.
Like other animal, Iguanas also need a day and night cycle in enclosure. As a basic guide, Iguanas need 14 hours of light and 10 hours of darkness. When it is the night time, you will need to turn of the white light and UVB light source to give the iguana a light-dark cycle. A ceramic heat bulbs with no light emitted may need to be added.
