Best UVB bulbs for tortoises Reviewed

Indoor housed tortoises have very different kinds of needs as compared to the ones that are found in the wild. They not only depend on you for food but also other things that you might not know about. This means finding one of the best UVB bulbs for tortoises is an important factor in owning a tortoise.


As they live in a tank all-day that has a very different environment as compared to their natural habitat, they miss out on a lot of essential things that are necessary for their overall development. A UVB light is the most important one among them. 
In the wild, tortoises get UVB light directly from the sun that provides the vitamins and heat needed for bodily functions. Tortoise owners think keeping the tank near the window is a viable solution to this problem; it is not. 
Sunlight that falls on the tanks or the enclosures heats the tank, which is partially beneficial. The glass and other materials block the vitamin D3 that tortoises need for bone development. Without it, tortoises develop bone disorders such as metabolic bone disease which can be life-threatening. 
Now that you know the importance of a UVB light, it would be better if you purchase one for your terrapin’s terrarium. To help you out, we have prepared a list of the best UVB bulbs for tortoises that can help your pet terrapin to a great extent.

Here are the answers to some of the common dilemmas faced by people when buying a UVB bulb for their pet tortoise. 

Do I Need UVB Lighting for My Tortoise or Turtle?

Many people opt out of buying a UVA and UVB light when purchasing essentials for their pets. It is not that these people lack affection towards their terrapin friends, but they rely on the store associate’s advice who tells them UVB lighting is not necessary. 
The absence of UVB lighting puts your tortoise at the risk of developing metabolic bone disease, becoming unable to synthesize Vitamin D, get lethargic, and lack of appetite.

How much light, heat, and UVB does a tortoise need?

Tortoises need three essential things to have a healthy life such as light, heat, and UVB. Depending on the species and their origins, the quantity of these three things varies massively. For instance, European tortoises that originate from temperate climates need less heat as compared to Mediterranean or tropical tortoises that are familiar to a much warmer temperature. To help you understand better, we have categorized some common tortoise breeds by common setups. 

European Tortoises: 

They are most comfortable outdoors, the European tortoises like Horsfield and Russian prefer a temperate climate. You can get a UVB lamp that provides around 10% to 12% UVB light, and set the heating around 34 degrees as the basking temperature. 

Mediterranean Tortoises: 

These tortoises prefer warmer temperatures, species like Marginated, Greek, and Leopard tortoises need 12% UVB for vitamin D3 synthesis, and the basking temperature set to 34 degrees celsius at the hot end. 

Tropical Tortoises: 

Since they originate from tropical regions, they prefer hotter temperatures for metabolic function such as 34 degrees Celsius or more. Tortoises like Redfoots get little UV in comparison due to the rainforest canopy; you can get a UV bulb of 5/6 percent that are suitable. 

What are the UVA light options for tortoises?

There are many light options available for tortoises these days, but the most traditional type of UVB light is the fluorescent strip light. This bulb looks like any other bulbs that are seen on the ceilings of most schools or places of business.Compact fluorescent UVB bulbs have a similar appearance like that of a corkscrew and have small fluorescent tubes that make the bulb. You can opt for this bulb if you have an extra clamp light laying around. The only problem with these bulbs is they cover a small area. 
Mercury vapor bulbs are quite expensive, but they are more durable as compared to the other options. These bulbs are more powerful than other UVB bulbs and also emit heat. They make an optimal alternative for large enclosures or rooms that house bigger tortoises. 

Conclusion Best UVB Bulbs For Tortoises 

It is common to develop a notion that tortoises are tough creatures, which is true; but only when they are in the wild. Housed tortoises don’t have the same immunity and strength and therefore depend on human interventions such as heaters, feeding dishes, and UVB bulbs.
