Our Specialized Items

Pro T5 UVB Kit

HO T5 UV-B Lighting Kit


ProT5 is a highly adaptable lighting kit with high quality internal electronics, a high effective but removable reflector, power cable, fittings kit, free link cable and choice of Arcadia Reptile HO-T5

UV-B lamp.


ProT5 uses the very finest electrical components to ensure safe running and long lamp life. Each bar has inbuilt over-voltage, over current, over heating and short circuit protection. ProT5 is Teflon free and free from any reflector coatings that absorb UV.

Heating

Our specialist lamps have been created to mostly emit Infra-Red energy (mostly IR-A). These are the wavelengths that allow reptiles to thrive.

 

These lamps are not designed to emit visible light and must not be used to illuminate buildings. For use with Reptiles, Amphibians, inverts and Plants only.

If an animal obtains everything it needs to thrive from its environment, it would only be right to mimic this in a natural way. We needed to ensure that any ingredients were safe, powerful and ethical. It is vital that we view the feeding of captive exotics at a multi-level approach. We believe in Wild Re-Creation and its positive effects upon captive animals.

We also know that a whole food for life simply cannot exist. No, we take cues for biological provision from nature and replicate that in a safe and in a measured way.

This theory is called ‘Wild-RecreationTM’ and within its parameters, are hidden all the secrets of fantastic animal care.

Fire, the Sun & Its Replication in Reptile Keeping

Did you know that light is as much a part of amphibian nutrition as water? Understand the importance of heating and how UV-B is converted to usable vitamin D3.

Discover how a lamp actually works and how to get the very best out of it. See your own animals thrive in your care.

This easy-to-understand guide, the first in a brand new series will explain everything that you need to know to go on to further investigate and understand ‘overall nutrition’. while expanding on the ‘Theory of Wild Re-Creation™’.

Topics covered include: how the sun provides us with energy; how lamps work, UV, infrared, light meters, LEDs, PAR, PUR, CRI, Kelvin, habitats, ‘Light & Shade’, MBD, basking and much more.
The Arcadia Guide to MBD and its elimination in captivity

Metabolic bone disease (MBD) is a killer of captive reptiles. These three letters strike fear into the heart of every reptile keeper and rightly so. MBD is a painful but avoidable condition that can effect captive reptiles and amphibians.

In this full colour guide you will not only learn what MBD is and its causes but you will also find a clear and up to date solution that can be applied in the home.

This title covers MBD as a disease, diet, hydration and new technology. Written by the experts from Arcadia reptile the worlds number name in reptile science this is a practical and easy to understand guide to MBD and our ultimate goal of its total eradication in captive animals.

The Light and Shade Method

🌡️ The Light and Shade Method

Reptiles rely on a thermal gradient to regulate their body temperature, and this method provides a practical way to create that gradient inside an enclosure. The foundation of proper reptile care is maintaining a warmer zone at one end of the vivarium and a cooler zone at the opposite end. The Light and Shade Method builds on this by ensuring that the warm end also includes the correct amount of full‑spectrum + UVB light, creating natural zones that range from “heat and light” to “cool and shade.”
 

☀️ Why Heat and Light Must Stay Together

The sun delivers all terrestrial wavelengths—from UVB to Infrared‑B—as a single, unified source of energy. It provides heat, visible light, and UV simultaneously. Because of this, it’s important not to separate heat and light sources in captivity.

Heating and lighting equipment should be positioned close together and safely directed onto the basking area. This allows the reptile to use the energy naturally and regulate its exposure just as it would outdoors.
 

🏜️ Creating Functional Zones

Once the basking area is established, the warmer, brighter zone should be separated from the cooler, more humid end of the enclosure. Proper zoning is essential for recreating terrestrial light conditions. It enables the reptile to self‑select and self‑regulate its exposure to heat, full‑spectrum light, or shade according to its biological needs.
 

🌿 Supporting Natural Behaviour

When the Light and Shade Method is used together with plenty of hiding places, the reptile can move freely through the enclosure and choose where to bask or retreat. This approach forms the basis of Wild Re‑creation®, allowing the animal to behave as naturally as possible within a captive environment.

The D3 Cycle

D3 Cycle description

Reptiles depend on heat, visible light, UV‑A/UV‑B, food, and water to survive and to successfully reproduce. Responsible keepers aim to replicate these natural environmental cues as closely as modern technology allows. The D3 cycle is one of the most important biological processes influenced by these factors, relying on access to natural light, warmth, cooler resting areas, and periods of recovery.
 

How Vitamin D3 Production Begins

Reptiles produce a natural cholesterol in the skin called pro‑vitamin D (7DHC), the same precursor found in humans. When this compound is exposed to natural sunlight—specifically UV‑B wavelengths between 290–315 nm—it is converted within the skin membrane into pre‑vitamin D.
 

Warmth then triggers the next step: pre‑vitamin D transforms into vitamin D3 within the skin. This vitamin D3 enters the bloodstream and binds to a vitamin D binding protein, which transports it to the liver.
 

Conversion Into Essential Hormones

Inside the liver, vitamin D3 is converted into calcediol (25‑hydroxy vitamin D3). This hormone circulates through the bloodstream and reaches the kidneys, where part of it is converted into calcitriol.
 

Calcitriol is vital for:

  • Regulating blood calcium levels and supporting calcium metabolism

  • Strengthening the immune system

  • Supporting cardiovascular health

  • Reducing the risk of certain cancers, including skin cancers
     

Why Completing the Cycle Matters

Sunlight exposure is only the first step in this complex process. If any part of the D3 cycle is interrupted, the chain cannot be completed. This leads to reduced production of essential vitamins and hormones. If supplementation was not used, a calcium crash could happen.
 

UV Light Beyond the D3 Cycle

While UV exposure is essential for vitamin D3 production, its influence extends far beyond this single process. UV light also affects:

  • Vision and colour perception

  • Breeding behaviour

  • Mental and behavioral well‑being

These additional roles are well documented and continue to be explored through ongoing research.
