REPTI HOME 100W Reptile Heat Lamp Bulbs
The REPTI HOME heat lamp bulbs simulate sunlight to help reptiles create a basking zone in their enclosure. They are designed for rapid heating, concentrating light and heat below the bulb to reduce heat loss and deliver a quick temperature rise. While primarily a heat source, these bulbs support a natural daytime cycle once paired with a proper lamp fixture. They’re compatible with bearded dragons, tortoises, lizards, and other common reptile pets, making them a versatile option for larger tanks.
- Simulated sunlight promotes basking and comfort for thermoregulation
- Advanced shape design concentrates heat efficiently
- Rapid warming to reach target basking temperatures
- Suitable for bearded dragons and multiple reptile species
Hygger zoo T5 UVB Reptile Light Fixture HO UVB 10.0

REPTITRIP Dual Reptile Light Fixture With Switches
The REPTITRIP dual fixture offers two independent switches, allowing separate control over heat lamps and UVB lighting. Its reflective interior boosts light and UVB efficiency, ensuring a more uniform illumination across the enclosure. Each socket supports up to 160W, enabling a flexible setup that can accommodate ceramic heat emitters or UVB bulbs alongside a basking lamp. This configuration can simplify 24-hour cycle planning when paired with a separate night heat source or ceramic emitter.
- Enhanced UVB and light reflection for even coverage
- Two independent switches for precise control
- Each socket supports up to 160W lamps

REPTIDLDB 8W T5 10.0 UVB Reptile Light Fixture 12″
The REPTIDLDB T5 fixture includes a UVB 10.0 bulb kit, delivering 10% UVB and 30% UVA output for a balanced daylight-like spectrum. The unit emphasizes minimal heat emission, reducing the risk of overheating while maintaining a bright, natural-looking environment. The UVB bulb is replaceable to preserve consistent radiation levels over time. An alloy reflective layer enhances UVB output, and the fixture is designed for 12-inch terrariums, offering a compact yet powerful lighting solution for bearded dragons and other desert and tropical reptiles.
- UVB 10.0 output supports calcium synthesis
- Low heat emission for safer basking zones
- Replaceable UVB bulb with durable reflector
- 12-inch fixture ideal for small to mid-size tanks
ReptiKing Basking Light for Reptiles, 2-Pack 100W
The ReptiKing basking bulbs provide an intense, targeted beam that creates a defined hot zone in the terrarium. This helps thermoregulation by creating a clear hot and cool gradient, enabling natural ecological behaviors. While the bulbs deliver UVA warmth, be mindful that these are primarily heat sources and may not provide UVB radiation by themselves. They pair well with UVB fixtures to maintain a robust daytime photoperiod and can be used in a 24-hour cycle when combined with other heating elements.
- 2-pack 100W basking bulbs for strong thermoregulation
- Narrow, intense beam to form a distinct basking zone
- UVA warmth supports activity and appetite
- Pair with UVB sources for a complete setup
Buying Guide
Key considerations for bearded dragon lighting
Bearded dragons require a careful balance of heat and UVB to support digestion, bone health, and overall vitality. The right setup combines a basking heat source with UVB exposure that falls within the recommended spectrum for desert-dwelling reptiles. Selecting fixtures that fit your enclosure dimensions, safety needs, and energy preferences will help you maintain a stable day-night cycle and minimize stress for your pet.
UVB vs Heat: how to balance
UVB exposure supports calcium absorption, while heat drives digestion and metabolic rate. For many setups, a basking lamp paired with a UVB fixture is ideal. If you choose a single fixture, ensure it provides both light and UVB, or install two separate sources with appropriate spacing. Regularly monitor temperatures with a reliable thermometer and use a thermostat or dimming controller to maintain stable basking temperatures without overheating.
Fixture types and enclosure compatibility
Heat lamps (often in the 60–150W range) create a warm basking spot, while UVB fixtures (T5 or LED-based) deliver essential ultraviolet radiation. T5 UVB tubes are efficient for mid-to-large enclosures, while compact LED UVB options suit smaller tanks. Check lamp dimensions and cord length to fit your terrarium and ensure compatibility with your reflector and hood. Durability and heat dissipation are important for long-term use in hot reptile environments.
Distance, placement, and safety
Position basking lamps 8–12 inches from the hottest spot, adjusting based on enclosure height and temperature readings. UVB fixtures should cover as much of the basking area as possible without creating excessive heat, often mounted above or at the side of the basking zone. Always provide a cool zone and a gradient for thermoregulation, and avoid placing lights directly over water or sensitive electronics. Regularly replace UVB bulbs according to manufacturer guidance to maintain effective radiation levels.
Durability, energy use, and maintenance
Look for fixtures with robust housings and good heat dissipation to extend service life in hot terrarium environments. Higher UVB output is beneficial, but efficiency matters for ongoing energy costs. Replace UVB bulbs on a schedule to prevent diminishing output, and inspect cords and mounting hardware for wear. A well-installed setup reduces maintenance while keeping your bearded dragon happy and healthy.
Comparison snapshot
| Product | UVB | Heat Source | Best For |
|---|---|---|---|
| REPTI HOME 100W Reptile Heat Lamp Bulbs | Not specified | Heat lamp | Basic basking heat for larger enclosures |
| Hygger zoo T5 UVB Reptile Light Fixture | UVB 10.0 | Heat via separate fixtures possible | Strong UVB for vitamin D3 synthesis in small-to-mid tanks |
| REPTITRIP Dual Reptile Light Fixture | Yes (UVB) | Heat and UVB separated with two switches | Flexible control for precise bearded dragon lighting |
| REPTIDLDB 8W T5 10.0 UVB Fixture | UVB 10.0 | Low heat emission | Efficient UVB in compact 12″ form |
| ReptiKing Basking Light | UVA (not UVB) | Heat only | Strong basking heat in a two-bulb setup |
Choosing the right combination depends on your tank size, bearded dragon’s age and activity level, and your preferred maintenance and energy costs. For many hobbyists, pairing a high-UVB fixture with a separate basking heat lamp delivers the most reliable, adjustable environment. If you have a smaller enclosure, compact T5 or LED UVB options paired with a dedicated basking lamp can minimize heat spikes while ensuring adequate exposure. Always monitor the habitat with thermometers and adjust placement as the dragon grows or the enclosure changes.
