DOMICA Reptile Heat Lamp With 50W UVA UVB

Features include heat-resistant aluminum alloy coating and reinforced ceramic base for safety. It offers 360° rotation to optimize heat distribution and includes an exclusive heat dissipation air duct that runs cooler than traditional lamps. Safety tips emphasize mounting distance, gloves when adjusting angles, and periodic rest intervals to prevent overheating. The lamp is veterinarian-recommended for reptiles and amphibians, helping mimic natural sun warmth essential for metabolism and calcium uptake.
Petboda Reptile Heat Lamp Dual Head

This dual-head setup expands the basking area and includes a timer with three brightness settings, enabling continuous or timed operation. The 15.2-inch goosenecks rotate 360 degrees, and a strong clamp with a sponge pad supports flexible mounting for terrariums, aquatic tanks, or enclosures. The design aims to maintain consistent warmth while supporting appetite and calcium absorption through UVB exposure.
REPTI HOME UVB Reptile Light 5.0

REPTI HOME’s 5.0 UVB bulb emphasizes vitamin D3 synthesis and calcium absorption. It uses a durable glass tube and stable electronics to maintain consistent UVB output, with a recommended minimum distance of 20 cm from the reptile. The bulb is compatible with standard E26 sockets and targets tropical and subtropical reptiles, including turtles, chameleons, and iguanas, promoting healthy bone growth and behavior.
Zoo Med Turtle Lamp Combo Pack

Zoo Med’s ReptiTuff splashproof halogen lamps are designed for aquatic turtles and water-based terrariums. The combo pack provides UVB essential for bone health and shell development, simulating sunlight to support productive daily activities and natural behaviors in turtles and tortoises.
LUCKY HERP UVA UVB Reptile Light 10.0

The 10.0 UVB bulb delivers a robust UVB output with 30% UVA, designed to mimic desert sunlight. It emphasizes a long UVB lifespan and high color rendering (CRI up to 90%), helping visibility and natural color fidelity for observing reptile health and behavior. The bulb is suitable for bearded dragons, lizards, tortoises, and similar species, with a focus on appetite, activity, and calcium metabolism.
Buying Guide: Key Purchase Considerations
- UVB output and UVA balance: Look for bulbs with a clear UVB percentage (e.g., 5.0, 10.0) and UVA support to facilitate vitamin D3 synthesis and natural behaviors.
- Wattage and heat output: Match wattage to tank size and basking zone needs. For smaller enclosures, 13–50W options are common; larger habitats may require higher output or multiple lamps.
- Distribution and mounting: Options with 360-degree rotatable heads, adjustable goosenecks, and sturdy clamps help achieve even heat distribution without overheating surfaces.
- Safety and materials: Opt for heat-resistant housings and components designed for reptile use. Follow mounting distance guidelines to prevent burns or equipment failure.
- Durability and lifespan: UVB output degrades over time. Choose bulbs with reputable build quality and plan regular replacements to maintain proper exposure.
- Regional needs: Desert-dwelling reptiles often benefit from higher UVB output, while tropical species may require a balanced mix of UVB and UVA depending on enclosure setup.
- Compatibility and fixtures: Verify socket type (commonly E26) and compatibility with existing fixtures or domes to ensure safe installation.
- Cost of ownership: Consider replacement bulb frequency, energy usage, and any additional features like timers or dual-head designs for efficient basking zones.
When installing UVB lighting for turtles, combine with appropriate heating and basking spots to create a gradient that supports thermoregulation. Maintain clean enclosures, monitor shell and bone health, and adjust light placement as your turtle grows or changes habitat conditions. Always follow manufacturer safety guidelines and local regulations for reptile care.
