Overview of ReptiZoo 5.0 Reptile Heat Lamp
As a long-time reptile enthusiast and owner of several exotic pets like chameleons, leopard geckos, and crested geckos, proper reptile housing and heating is incredibly important for their health and wellbeing.
After extensive research, I decided to try out the ReptiZoo 5.0 reptile heat lamp based on the stellar online reviews and recommendations from fellow reptile owners on forums.

1. Brief Description and Key Features
The ReptiZoo 5.0 is a self-ballasted mercury vapor bulb that provides both heat and UVA/UVB light in one convenient bulb. The spiral compact bulb design produces focused directional lighting, unlike diffuse heat emitters.
The key features include:
- UVA/UVB light spectrum ideal for reptiles
- Powerful 125W output for basking temps up to 110°F
- Energy efficient, only uses 125W of electricity
- Lasts up to 6 months of continuous use
- Safe for use in glass terrariums or wire cages
2. Different Models and Wattages
ReptiZoo offers these heat lamps in a variety of wattages depending on your reptile’s size and heating needs:
- 75W for small terrariums up to 20 gallons
- 100W for medium terrariums 20-40 gallons
- 125W for large terrariums over 40 gallons
- Flood light models available for extra wide heat coverage
I chose the 125W model for my 40 gallon chameleon terrarium since Bert needs high basking temps up to 110°F. The higher wattage allowed me to achieve an ideal thermal gradient.
3. Benefits of Reptile Heat Lamps
Unlike heat mats or ceramic bulbs, heat lamps like the ReptiZoo 5.0 provide more natural heating that reptiles instinctively bask under. The bright light and warmth mimics the sun, allowing for:
- Proper vitamin D3 synthesis from UVB rays
- Adequate digestion and feeding
- Increased activity levels and health
- Thermoregulation and prevention of metabolic issues
For many reptiles, heat lamps are an absolute necessity. The ReptiZoo 5.0 heat lamp offers the full benefits of heat and light in a quality bulb.
4. Proper Reptile Heating
As reptiles are cold-blooded, they rely on external heat sources to maintain their body temperature. Each species requires different optimal temperature gradients with a hot basking area and cooler hide.
Having the wrong heat gradient can lead to:
- Digestive problems and appetite issues
- Thermoregulation difficulties and illness
- Lethargy, stress, and poor activity
Proper wattage selection for your ReptiZoo heat lamp helps ensure your chameleon enclosure has an appropriate hot zone for healthy function.
5. Reptiles Requiring Heat Lamps
Nearly all diurnal lizards and some nocturnal geckos require specialized overhead heating from lamps like the ReptiZoo 5.0. Common species include:
- Bearded dragons
- Leopard geckos
- Crested geckos
- Blue-tongued skinks
- Uromastyx
- Anoles
- Chameleons
- Iguanas
Even small tropical geckos benefit from a low wattage directional basking light for proper health and activity.

In-Depth Review of ReptiZoo 5.0 Reptile Heat Lamp Features
After installing the ReptiZoo 5.0 in my bearded dragon’s 40-gallon terrarium, I carefully tested all of the key features and performance metrics over a two month period. Here is my detailed review:

UVA/UVB Light Spectrum
The light spectrum plays a crucial role in a reptile’s health. The ReptiZoo 5.0 produces:
- 5% UVA for natural visible light
- 5% UVB for vitamin D3 and calcium metabolism
- 90% infrared heat
I tested the UVB output using a SolarMeter 6.5R. The UV index measured 0.5-2.0 in the basking zone – perfect for a bearded dragon’s needs.
Heat Output and Temperature Regulation
With the 125W lamp, the basking area reached 105-110°F, creating an ideal 95-110°F gradient in a 4 ft long terrarium. The temperature can be easily adjusted by raising or lowering the dome fixture height.
The lamp took only minutes to heat up to full brightness and maintained a consistent temperature throughout the day without annoying fluctuations.
Bulb and Housing Durability
The compact spiral bulb design allows for safe handling – an improvement over fragile wire coil bulbs. The thick glass housing also protects the inner components well.
After 8 weeks of use for 12 hours daily, my 5.0 bulb still looks and functions like new. I expect to easily get the full 6 month lifespan.
Energy Efficiency
Despite the high 125W output, the ReptiZoo 5.0 uses less electricity than typical incandescent heat lamps. The average monthly cost for daily use was only $3-5.
The directional light focuses heat right where needed instead of wastefully heating the entire room. It’s an energy-efficient choice.
Safety Features and Certifications
Importantly, the ReptiZoo heat lamp is ETL certified to meet the latest safety standards in the US and Canada. The housing stayed cool enough to touch.
The included warnings ensured I took precautions like proper fixtures and positioning. Used correctly, it’s safe for unattended operation.
Next I’ll go over the ideal setup and usage tips for the ReptiZoo 5.0 reptile heat lamp…
Using the ReptiZoo 5.0 Reptile Heat Lamp
Based on my experience using the ReptiZoo 5.0 bulb for my bearded dragon’s terrarium, here are my top tips for setup and usage:

1. Lamp Setup and Positioning
The 5.0 bulb should only be used in a dome lamp fixture rated for at least 150W bulbs. Position it at one end of the tank to create a thermal gradient. For bearded dragons, place it around 8-10 inches above the basking area.
2. Temperature Monitoring and Adjustment
Use a digital thermometer to monitor basking area temps. If needed, adjust the fixture height to fine-tune the temperature to the ideal range for your reptile species. Unplug the lamp if the area exceeds 110°F.
3. Compatible ReptiZoo Products
The 5.0 bulb works great paired with ReptiZoo’s line of glass terrariums and screen cages. For large tanks, use their high quality ceramic dome fixtures. Their dimmable thermostats allow automated temperature control.
4. Species Heating Requirements
Always research your specific reptile’s ideal heat range. The 125W ReptiZoo bulb works well for species needing a 100°F+ basking area, like bearded dragons and leopard geckos. Lower wattages may be better for smaller cold-blooded pets.
5. Safety Precautions
- Never touch bulb or fixture with bare hands while hot
- Check wire insulation; stop using if damaged
- Place lamp out of reach of children and pets
- Avoid combustible materials nearby
- Plug into a surge protector, not an extension cord
