best reptile light fixtures

Light is a very important part of reptiles and it helps in physical growth and psychological development.

Human activities are dictated by the position of the sun and this also is the case with animals.

As they do not have clocks to tell the time, they rely solely on the amount of light they get to be active or rest.

Keeping your pet reptile indoors means it will be denied of the natural day and night cycle and so you have to make up for this.

The best way to provide proper lighting for your pet reptile is with the use of the best reptile light fixture.

The circadian rhythm is very important and light and heat are essential in dictating this.

Without a proper rhythm, your pet’s behavior will not be healthy as it won’t know when to eat or sleep. Stress on your reptile friend will be increased and its health quality will drop.

UVA and UVB are very necessary for the health of your reptile pal and they get these from the sun while in the wild. UVA is necessary for the regulation of behaviors like mating, diurnal movement, feeding, and the like.

While UVB is necessary for vitamin D3 synthesis for calcium absorption. Without a source of UVB your pet will develop metabolic bone disease, and weak shell (for tortoise and turtles).

A lot of light fixtures are in the market and all promise quality performance but is this always the case?

In this article, we will show you our top picks based on performance, and give you a guide on making the best choice for you.

After seeing numerous light fixtures, we have a pretty solid idea of what characteristics make the best light fixture for reptiles, and the Fluker’s Repta-Clamp Lamp it’s our top choice.

  • Works best for all types of enclosure
  • All sizes feature safety clamp

Reptile UVB Lighting Guide

Reptiles have a great need for proper lighting and it is important that this is included in your pet’s enclosure.

Being cold-blooded, reptiles cannot regulate their own core temperature and so depend on external heat to keep warm.

This, together with their need for vitamin D3 for calcium absorption makes the presence of light and heat very necessary in their enclosure.

Not all bulbs are sources of UVB, only UVB lights emit UVB so take note of this. Exposure to UVB allows reptiles to synthesize vitamin D3 that is necessary for calcium absorption.

Lack of UVB can cause health issues like metabolic bone disease, soft bones, and deformation, as well as other bone-related diseases.

UV Index

The UV index is a measure of ultraviolet radiation. The UV wavelengths measured here are those that contribute to a reptile’s manufacture of vitamin D3.

Not all UVB wavelengths are equal in their roles for vitamin D3 synthesis and with the UV index, you can measure the amount of useful UVB emitted.

Safe Use of UV Lights

It is not all about making the right purchase as less than optimum performance can also be gotten from the best products if used wrongly.

UV lights are not like regular lights and so to get the most out of them, they have to be used correctly.

Most times each product comes with its own instruction from the manufacturer which you have to follow, but these guidelines are going to help you care for your pet better:

  • While creating a hot zone for your reptile to bask on, it is important to note that the use of highly focused lights is not the best to achieve this. Make use of lights whose field covers the entire body of your animal rather than heating up one small spot.
  • Do not place UV light fixtures at the side of your pet’s enclosure. Most reptiles have developed thick ridges above their eyelids to protect their eyes from the sun above. And so placing the light fixtures at the side allows glare into their eyes directly and it can be harmful.
  • Ensure that you maintain an appropriate distance between your reptile and light fixture. At least 6 inches and no more than 18 inches is good enough to prevent burns and reduced UVB respectively. The best practice is to maintain a 12-inch gap between both reptile and light fixtures.
  • Avoid direct eye contact with the UV light. Ensure that the light is kept out of direct eyesight from yourself, children and your pet reptile also.
  • UV lights produce diminishing amounts of UVB over time and will need to be replaced. Most manufacturers recommend a change at 6 or 12 months.
  • Do not fill the entire enclosure with UVB. Provide a kind of shade under which your pet can stay away from the UVB light if it so desires. Also, endeavor to maintain a 12-hour cycle of day and night.

How to Choose the Best Reptile Light Fixture

Even though the majority of reptiles have the need for UVB and an external source of heat, their requirements vary and it depends on the species you have.

So before you make any purchase, it is important that you know the UVB needs of your pet so it doesn’t suffer from deficiencies.

Pets with a low need for UVB and heat can make do with regular UVB lights, but those with a higher need (like the turtle, bearded dragon, tortoise, iguana, chameleon, etc.) will need you to get a specific UVB bulb.

The light fixture should be able to provide light during the day and stay off at night so as to maintain a healthy cycle for your pet.

Not all light fixtures can handle high amounts of heat and so be sure that if your pet needs much heat and UVB, the light fixture is able to withstand it.

Commonly Asked Questions About Light Fixtures

Q: What Is UVB?

UVB is part of the sun’s spectrum that is necessary for reptiles to be able to produce vitamin D3. You need to make this available for your pet in its enclosure to prevent bone diseases from occurring. 

Q: Can Reptiles Get Too Much UVB?

Yes, they can and that is why they regulate their intake of it. When setting up their enclosure, do not have the whole space under UVB, but provide shades where they can hide under when they need a break from the radiation. 

Q: Are Red Lights Bad For Bearded Dragon?

You should avoid the use of red lights at night with your bearded dragon. Unlike most reptiles, bearded dragons can see the red light at night and their sleep disturbed.

Q: Do Halogens Give Off UVB?

Halogens are known to emit higher levels of UVB together with mercury vapor bulbs. They also give off heat and so their use can save you the need for an additional source of heat within the enclosure, depending on your poet’s needs.
