Things to Consider Before Buying the Best UVB for Bearded Dragon

The wattage of the bulb:

Bearded dragons require a UVB emitting bulb of 10-20 watts, depending on the size of the enclosure. The bulb should be placed approximately 12″ away from the dragon’s basking spot and never be placed directly over the dragon’s head to avoid burns. The bulb should be changed every 6-12 months to ensure proper UVB exposure. Additionally, the basking light should be at least 80-90℉.

Size of the enclosure:

Bearded dragons typically need a minimum of a 20-gallon tank with a secure lid to prevent escape. The tank should be as long as possible, ensuring it is at least three times as long as the dragon’s body. Be sure to provide plenty of perches and hiding spots for the dragon to explore and feel secure. The tank’s temperature should also be monitored, as it should not exceed 90 degrees Fahrenheit. The tank should also be equipped with a UVB light to help the dragon synthesize calcium and other vitamins.

Spectral Range of the bulb:

Bearded dragons require lamps that emit UVA and UVB light. UVA light helps to stimulate their activity, and UVB light helps them absorb calcium and helps in the metabolism of Vitamin D3. This is necessary to prevent metabolic bone disease. The ideal spectral Range of the bulb should be between 290nm and 320nm.

Bulb size:

Bearded dragons require a UVB lamp that is specifically designed for reptiles. The lamp should be the correct size for the tank. Too small light won’t provide enough UVB, and too large a lamp may cause too much heat. It is important to use the correct size lamp for the tank size. A 10-20 gallon tank will require a 20-30 watt bulb. A 20-40 gallon tank will need a 30-50 watt bulb, and a 40-gallon or larger tank will require a 50-75 watt bulb.

It is also important to use a fluorescent lamp as incandescent bulbs don’t emit UVB. Bearded dragons require both UVB and UVA for their overall health. UVB helps with

Duration of the bulb’s lifetime:

Bearded dragons usually require 12 to 14 hours of UVB light daily, so the bulb should be replaced every 6 to 8 months. This ensures that the dragon receives enough sunlight to produce adequate Vitamin D3 and promote healthy bone development. The bulb should be replaced more often if the dragon is kept in a room exposed to direct sunlight, as this could significantly reduce the bulb’s lifetime. Additionally, the bulb should be replaced immediately if it is cracked or broken.
