Owning a bearded dragon is a rewarding experience, but providing the right environment is crucial for their health and happiness. A significant component of this is ensuring your dragon receives the optimal amount of UVB and basking light, vital for proper calcium absorption, digestion, and overall wellbeing. Inadequate lighting can lead to serious health problems like Metabolic Bone Disease (MBD), a debilitating and often fatal condition. Therefore, creating a perfect lighting setup is paramount.
Understanding the nuances of bearded dragon lighting can be tricky, navigating the options available and making informed choices about wattage, placement, and bulb types. This article provides a comprehensive guide to achieving the perfect balance of UVB and basking heat, leading you through a step-by-step process to ensure your bearded dragon thrives. Let's dive into creating the ideal lighting environment for your scaly companion.
Preparation and Safety Guidelines
Tools Needed
- Arcadia 12% or 14% UVB bulb
- Two 80W halogen heat lamps (or Zoo Med 100W)
- Temperature gun
- Solar meter (optional)
- LED grow light (optional)
- Zip ties (for mounting UVB inside enclosure)
- Screwdriver
- Small screws (for mounting UVB inside enclosure)
Safety Guidelines
- Never use incandescent or halogen bulbs for UVB; they produce minimal UVB and excessive heat, risking burns.
- Ensure the UVB bulb is the correct distance from your dragon; too close causes burns, too far is ineffective. Check manufacturer's guidelines.
- Replace UVB bulbs every 6-12 months, regardless of whether they appear to still be working. UVB output degrades over time, even if the bulb still lights up.
Step-by-Step Instructions
Choosing and Positioning UVB and Heat Lamps
- Position UVB and heat lamps on one side of the enclosure, adjacent to each other. This ensures your dragon receives both UVB and heat while basking.
- Use Arcadia 12% UVB if your basking spot is high (at least 12 inches away from the bulb). For screen-top enclosures, opt for the 14% UVB due to UVB loss through the mesh.
Choosing and Positioning UVB and Heat Lamps Setting and Maintaining Temperature
- Monitor basking spot temperature with a temperature gun, aiming for 104-110°F. Adjust bulb wattage or distance to achieve this.
- Maintain ambient temperature in the 80-90°F range. This provides a thermal gradient, allowing your dragon to regulate its body temperature.
Setting and Maintaining Temperature Measuring UVB Intensity
- Measure UVB intensity with a solar meter (optional). Ideal UVB values are 3.0 to 7.4 at the basking spot. Adjust bulb position if needed.
Measuring UVB Intensity Mounting the UVB Bulb (Screen-Top Enclosure)
- If using a screen-top enclosure, mounting the UVB bulb *inside* the enclosure with zip ties and cut holes in the screen is advised to increase UVB penetration.
Mounting the UVB Bulb (Screen-Top Enclosure) Mounting the UVB Bulb (Closed-Top Enclosure)
- For closed-top enclosures, use the mounting screws provided with the UVB bulb to attach it to the top. If necessary, replace the provided screws with smaller ones to prevent them from popping through the enclosure top.

Tips
- Ensure a thermal gradient by providing both a basking spot and a cooler area. Your dragon will move between the two to regulate its temperature.
- If your bearded dragon prefers basking under an LED grow light, increase the brightness of the cool side of the enclosure to prevent this. It's an indication that the basking side isn't bright enough.
- Adjust the number and type of heat lamps based on your climate and enclosure. One heat lamp may suffice in warmer climates without air conditioning.
- You don't need to use two UVB lights; this is shown in the video as an example for a specific enclosure type.
Common Mistakes to Avoid
1. Incorrect UVB Bulb Placement
Reason: Placing the UVB bulb too far from the basking spot or using the wrong type of bulb (e.g., coil instead of linear) results in insufficient UVB radiation, leading to metabolic bone disease (MBD).
Solution: Position the UVB bulb directly above the basking spot, ensuring it's the correct distance and type for the enclosure size.
2. Insufficient Basking Spot Temperature
Reason: A cool basking spot prevents the bearded dragon from properly digesting food and regulating its body temperature, impacting overall health and activity levels.
Solution: Use a reliable thermometer to monitor the basking spot temperature and adjust the heat source accordingly to reach the optimal range (100-110°F).
FAQs
What kind of UVB bulb is best for my bearded dragon?
Reptile-specific UVB bulbs are crucial. Look for a tube bulb (not a coil) that provides UVB output of 5.0% to 10%. T5 high-output bulbs are generally preferred for their better UVB penetration and longevity.
How far away should my heat and UVB bulbs be from my bearded dragon?
The distance depends on the bulb's wattage and your enclosure size. Aim for a basking spot temperature of 100-105°F (38-41°C) measured *on the surface* with an accurate thermometer. The UVB bulb should be positioned so your dragon can bask comfortably within its UVB range, ensuring they aren't too close to burn themselves, but close enough to receive sufficient UVB.
