Bearded dragon comes from hot desert areas from Australia where they received lots amount of sunlight. Basically, bearded dragons in the enclosure will need two types of light.
One is the basking light, which simulates the sun’s heat and provides heat for bearded dragons. In addition to heat and white light, bearded dragons also need UVB light, which helps them synthesize vitamin D3 and metabolize calcium.
Best UVB bulbs for bearded dragons
UVB bulb is absolutely essential for bearded dragons in the enclosure. UVB rays help bearded dragons manufacture vitamin D3, prevent metabolic bone disease.
The best way to create these rays is by using UVB bulb for bearded dragon. It can be fluorescent or mercury vapor light bulbs. Their full-spectrum bulbs always available but there are some types of them that will produce UVB that too strong for bearded dragon and can burn them.
Fluorescent bulbs have a reasonable price. Every six months you need to replace this bulb because the bulb will not emit enough UVB rays after this time.
Mercury vapor bulbs are more expensive but it will emit much amount of UVB and also last for longer. Due to its feature of high powered, you have to often measure the temperature inside the bearded dragon’s tank.
