Arcadia D3+ Compact Reptile Lamp 23W 12.0 UVB
Arcadia D3+ Compact Reptile Lamp 23W 12.0 UVB is a powerful compact UVB bulb designed primarily for sun-loving reptile species with higher requirements for ultraviolet radiation, such as bearded dragons, spiny-tailed lizards, monitors, or terrestrial tortoises. It provides 12% UVB and 30% UVA radiation, which supports natural visual perception and enables vitamin D3 synthesis, essential for proper calcium metabolism. With a power consumption of 23 W, color temperature of 7000 K, and compact dimensions, it represents a practical UVB radiation source for smaller terrariums or supplementary lighting for larger enclosures. It does not require an external ballast and can be easily installed into a compatible socket. For optimal light and UV radiation utilization, we recommend using a reflector and replacing the bulb no later than after 12 months of operation. The appropriate distance from animals must be adjusted according to their UV radiation requirements.

Product description
Arcadia D3+ Compact Reptile Lamp 23W 12.0 UVB – Compact UVB Bulb for Sun-Loving Reptiles
Arcadia D3+ Compact Reptile Lamp 23W 12.0 UVB is a powerful compact UVB bulb designed primarily for reptiles with higher requirements for ultraviolet radiation. It provides 12% UVB and 30% UVA radiation, which supports natural visual perception and enables vitamin D3 synthesis, essential for proper calcium metabolism and healthy bone development.
With a power consumption of 23 W, compact dimensions, and simple installation, it represents a practical solution for terrariums where it is not possible to use a linear UVB bulb. The color temperature of 7000 K provides clear white light resembling natural daylight.
Who is the bulb suitable for?
Arcadia D3+ Compact 12.0 UVB is designed primarily for diurnal reptile species inhabiting open and intensively sun-exposed habitats, such as deserts, semi-deserts, and savannas.
It can be used for breeding:
Bearded dragons (Pogona vitticeps)
Frilled lizards (Chlamydosaurus kingii)
Spiny-tailed lizards (Uromastyx)
Selected monitor lizard species
Terrestrial tortoises
Other diurnal reptiles with higher UVB radiation requirements
UVB radiation enables vitamin D3 synthesis in the skin, which is essential for proper calcium utilization. UVA radiation is involved in visual perception in many diurnal reptiles and can influence their natural behavior.
However, the designation 12.0 UVB alone does not determine the suitability of the bulb for a specific species. The actual intensity of UV radiation at the location where the animal is located is decisive.
Main advantages
12% UVB radiation: A variant designed for reptiles with higher ultraviolet radiation requirements.
30% UVA radiation: Supports natural visual perception and behavior of diurnal reptiles.
Support for vitamin D3 synthesis: UVB radiation enables its synthesis in the skin.
Power consumption of 23 W: Compact and energy-efficient UVB radiation source.
Daylight white light: Color temperature of 7000 K.
Simple installation: Integrated electronics allow operation without an external ballast.
Compact dimensions: Suitable where there is no space for a linear UVB bulb.
Possibility of using a reflector: Helps direct light and UV radiation to the desired part of the terrarium.
Recommended replacement: No later than after 12 months of use.
Proper placement and use
For safe and effective UVB radiation utilization, proper placement of the bulb in relation to the reptiles is important.
The appropriate distance depends on the specific species, its biological requirements, and the actual UV radiation intensity. For precise adjustment, we recommend measuring the UV index (UVI) with an appropriate measuring device.
We recommend installing the bulb into a suitable reflector, which helps direct light and ultraviolet radiation to a defined space.
During installation, it is also necessary to consider any obstacles between the source and the animal. Common glass blocks most UVB radiation and mesh can reduce its intensity.
The terrarium must always provide both lit and shaded areas, allowing animals to regulate their UV radiation exposure according to their needs.
Combination with daylight and heat source
Compact UVB bulbs provide only limited heat and their visible light intensity is usually insufficient for adequate lighting of terrariums with sun-loving reptile species.
We therefore recommend combining Arcadia D3+ Compact 23W 12.0 UVB with other light and heat sources according to the needs of the species being kept.
Suitable supplements may include:
LED lighting: To ensure intense daylight.
Heat lamp: To create a local basking area.
Linear UVB bulb: If the size of the terrarium and the requirements of the species require a wider area of UVB lighting.
The compact bulb is particularly useful where it is not possible to install a linear UVB bulb or where UVB radiation needs to be supplemented in a specific part of the terrarium.

Lifespan and recommended replacement
When using UVB bulbs, there is a gradual decrease in the intensity of ultraviolet radiation, although the source may continue to provide visible light.
To maintain suitable husbandry conditions, we recommend replacing the bulb no later than after 12 months of use. Actual efficiency can be checked by regularly measuring the UV index.
Arcadia D3+ Compact Reptile Lamp 23W 12.0 UVB represents a practical source of ultraviolet radiation for sun-loving reptile species. Due to its compact dimensions, simple installation, and the possibility of using a reflector, it is particularly suitable as a supplementary UVB source or for smaller terrariums where appropriate UV radiation intensity and safe distance from animals can be maintained.
