UVB T5 Bulbs
Manufactured in Germany to the highest quality standards, these durable Very High Output (VHO) UVA & UVB bulbs deliver exceptional performance. Their specialized phosphor blend closely replicates the sun’s UVB and UVA rays, helping to prevent metabolic bone disease by supporting healthy vitamin D3 production and improving calcium absorption. Additionally, the sun-like UVA and UVB light stimulates appetite, activity, and reproductive behavior in reptiles. Designed to mimic key parts of the sunlight spectrum, these bulbs offer excellent UVB penetration, making them ideal for use in tall terrariums. When paired with the T5 Terrarium Top, they ensure your reptiles receive the essential benefits of natural sunlight.

A Beacon of Life
Sunlight arrives at the top of the earth's atmosphere at a power level of about one kilowatt per square meter. It is by this energy that all life-processes on earth are ultimately driven. Without the sun's constant energy input our planet would quickly radiate away its own energy in short order, making all life extinct.
Vitamin D3 and Reptiles: A Vital Connection
Vitamin D3 plays a vital role in the health and well-being of reptiles, much like it does in other animals. This hormone is integral to mineral metabolism and bone development in reptiles. One of its most significant roles is to enhance calcium absorption from the intestines. Without sufficient vitamin D3, reptiles couldn’t absorb dietary calcium efficiently, which is crucial for their skeletal health and overall well-being.
The Myth of Nocturnal Creatures and UVB Light
The belief that nocturnal animals don't require UVB exposure has been a long-standing one in the world of reptile and amphibian care. The argument, "It’s nocturnal—it doesn’t need UVB," has been a staple for many enthusiasts and breeders. However, recent scientific studies have begun to challenge this age-old notion, shedding light on the importance of UVB for all creatures, regardless of their diurnal patterns.
Understanding Ferguson Zones
The Ferguson Zones were developed in 2010 by Professor Gary Ferguson of the Texas Christian University. Ferguson and his team of herpetologists gathered data of the daily UV exposure of 15 species of reptiles. In the publication that followed, these 15 species were divided into four groups according to their thermoregulatory behaviour (daily sun exposure) and microhabitat preferences: the "Ferguson Zones". The corresponding UV guidelines were based on the average irradiance of randomly encountered wild specimens: Zone 1 with the least, to Zone 4 with the highest exposure.
What is UV-B?
UV-B stands for Ultraviolet B radiation, which is a type of ultraviolet radiation present in sunlight. Ultraviolet or UV light is a high energy portion of the electromagnetic spectrum, just beyond visible light. The UV-spectrum is divided into three wavelength groups.
