REPTILE LIGHTING
ARTIFICIAL LIGHT. When keeping Reptiles in captive
environments we need to provide artificial sunlight. Not any old light will
do!!! There are specific Reptile lights sold by Pet Shops. Some are different
shapes and come in many different sizes. Every keeper needs to be made aware of what light
is right for their Reptiles well being. So here we go, and I hope that what you are about
to learn is not too confusing.
UVA / UVB. What does all this
mean??? The UV spectrum is broken up into three parts: UVA,
UVB and UVC, all of which are present in natural sunlight. UVA
and UVB are essential for Reptiles wellbeing. UVA is the
visible light range, and is responsible for normal behaviours such as feeding and
activity. UVB is a non-visible wavelength, and allows the synthesis of
vitamin D3, which helps process calcium and prevent Soft Shell in Turtles and
Metabolic Bone Disease in Lizards. (Metabolic Bone Disease is particularly common
with Bearded Dragons and Eastern Water Dragons that have incorrect lighting)
WHICH IS THE RIGHT LIGHT FOR MY REPTILE??? "Sun-worshippers".
Some Reptiles are described as "Sun-worshippers", including Bearded
Dragons, Eastern Water Dragons and many species of Turtles especially Red-eared Turtles.
In the wild these Reptiles spend many hours a day exposed to the sun and high UVB
levels. They require high levels of UVB!! If you keep any Reptile in
captivity in New Zealand, you are bound to have a "Sun-worshipper",
therefore it is imperative that you purchase a Reptile specific light with the highest
possible UVB output. The Florescent Tubes that you will find for
sale in New Zealand currently range from 2.0, 5.0, 8.0, and 10.0. These
numbers represent the percentage of UVB wavelengths that they give. The
higher the number the higher the percentage of UVB, the better that light
is for the wellbeing of your Reptile. We at Hot House Turtles
recommend no matter what Reptile is kept, that you use the higher UVB
percentage bulbs or tubes, either an 8.0 or 10.0.
Some of the Compact UVA / UVB Low-energy
Bulbs come with a percentage of UVB and some do not. I personally use Lucky-Reptile
Compact UVA / UVB. They don't claim a percentage of UVB given off, but I
have trialed these and find them to be brilliant. (These have also been tested by
www.uvguide.co.uk and come out with a glowing report.) They are the only UVB light that
has an effective range of up to 50cm from your basking Reptile,
so are ideal for deeper enclosures. These are the lights that are best
for the "Sun-worshippers" kept as Pets in New Zealand.
To us there is no compromise!!
INTENSITY OF LIGHT. Glass filters 95% of UVB.
Fly mesh filters 30% of UVB. It is best to have no lids
on your Turtle tanks, and to mount the light on the inside of your
Lizards environment. This will then ensure that your Reptile is going to get the full
benefit from the UVB given off. There are two types of Reptile bulbs
available, UVA / UVB Fluorescent Tubes and Compact UVA / UVB
Low-energy Bulbs. In order for your Reptile to gain the highest possible UVB%
from your bulb, the distance between your Reptiles sunning area and the UV bulb
must not exceed 300mm (unless you are using a Lucky Reptile Compact in which case you can
have your basking distance of upto 50cm). The further your Reptile is from the
light, the UV light levels are greatly reduced. Also note
that the Florescent Tubes and Compact Bulbs need to be changed as per the
manufacturers recommendations. Usually annually, as the UVA / UVB output
is reduced over time. Even though the light still goes, they are of no
benefit to your Reptile at all!!

AMOUNT OF LIGHT. 10 hours of artificial light is the minimum per day.
An easier way to make sure that your Reptile is getting enough UVB is to turn the lights
on when you get up in the morning and off when you go to bed.
