Why Is UVB Light Important For Reptiles?

What is UVB lighting?

UVB(ultraviolet radiation b), also named as medium wave erythema effect ultraviolet. The wavelength is 280~320nm. Almost 100% UVB will be absorbed by the normal glass, and most of the medium-wave ultraviolet rays contained in the sunlight are absorbed by the ozone layer, and only less than 2% can reach the earth's surface, which is particularly strong in summer and afternoon. UVB ultraviolet rays have erythema effects on the human body, can promote mineral metabolism and the formation of vitamin D in the body, but long-term or excessive exposure will make the skin tan and cause redness and peeling. UVB reptile bulb is made of special transparent purple glass (which does not transmit light below 254nm) and phosphor with a peak near 300nm.

Importance of UVB Reptile Lights

In the natural environment, UVB rays from the sun allow reptiles the ability to synthesize vitamin D3 naturally in the body. Reptiles cannot convert calcium from food and adjust the body's metabolism without vitamin D3. Calcium will be completely excreted through the digestive system without conversion and absorption. In this way, reptiles will not be able to grow and strengthen their bones, and they are more likely to develop cartilage lesions due to insufficient calcium.

Pets raised in most homes cannot get enough light to maintain their normal physiological activities. That's why UVB light is important for reptiles.

 

The most common parameter of UVB lamp on the market is 5.0, 10.0.

UVB light emits both UVA and UVB
5.0 provides 30% UVA and 5% UVB, suitable for reptiles in tropical/subtropical forest areas, such as IG, star tortoise and most tortoises.
10.0 provides 30% UVA and 10% UVB, suitable for reptiles in tropical deserts, such as king lizards, leopard tortoises, and sulcata tortoises.

 

Tips:

  1. UVB bulbs should be replaced every 6 months, to ensure a proper UVB output.
  2. UVB light will be blocked by glass, please take this into consideration when using UVB lamps.
