Top 10 Best UVB Light For Turtles with Buying Guide

I have to admit that creating a proper basking area for the turtles during the turtle tank setup was the most challenging part. I was lost among hundreds of choices for lights containing UVA and UVB rays, and every light seems to have claimed almost the same specifications, such as UV rating, 5.00 or 10.00UVB, and types of UV lights.

As I grew older as a pet turtle owner, I eventually found the best UVB light for turtles that suit their basking habit and don’t cost billions of dollars. Also, I learned which factors to consider for UVB light and which not to. Hence, I searched the internet to bring a comprehensive buying guide for the UVB light and suggestions for ten popular and reliable UVB lights for turtles.

Also, I will discuss the importance of UVB lights and the steps to set them up properly in a quick time for turtle owners’ convenience, especially if you are new in the turtle petting sector.

UVB Light Definition & Its Usefulness For Turtles

The UVB light is a specific portion found inside the UV-ray spectrum. The full range for the UV ray is 100-400nm.

Ideally, the UVB ray has a spectrum between 290nm-320nm. The UVB ray contains beneficial vitamin D3. Vitamin D3 is eventually necessary for the health of the turtles’ shells. When a turtle fails to absorb proper D3 vitamins, it fails to consume calcium adequately.

So, the shell and bone of the turtle start deteriorating, and eventually, the turtle will face an immature death.

So, mounting a UVB light with heat generation is a must for the proper basking of your favorite turtle. Also, it ensures the turtles’ metabolism remains satisfactory.

10 Best UVB Light For Turtles Reviews

Sun rays contain a UB spectrum that includes three different lights, such as UVA, UVB, and UVC. Among them, UVB rays are the most crucial for reptiles, especially turtles. It provides turtles with vitamin D3. Vitamin D3 helps turtles accumulate calcium, which is vital for their shell and bones. Lack of UVB light and basking will result in the immature death of turtles.

So, don’t ignore their importance. Read our full review of the 10 UVB lights and select which is your best alternative for a turtle tank setup.

UVB Light For Turtles: The Buying Guide

So, finally, you have decided to invest in a UVB light for your turtles’ health and happiness. I can’t step forward without congratulating you on such an excellent decision for turtles.

However, I must not forget that with tons of options choosing the most appropriate UVB light bulbs for terrariums isn’t an easy task. In fact, the selection of UVB light for turtles is pretty challenging with some technical terms and their misleading use by manufacturers. So, the following buying guide will help you get the best turtles’ UVB light with ease.

Full Spectrum

You will see that most manufacturers label their UVB lights with the term ‘full spectrum.’ So what does this means?

It implies that the light covers the entire 100-400 nanometer (nm) wavelengths for the bulbs. It means you get both UVA and UVB rays from the full spectrum lights. However, it brings a big issue in front of you.

The full spectrum also contains UVC rays, which are somewhat harmful to turtles and reptiles. So, we suggest you stop and think before making the final decision.

UVB Light Types

You will get three varieties of UVB rays generating bulbs when it comes to light sources. These are:

  • Strip fluorescent bulb: Much like traditional household fluorescent lights, it is the bulbs that we mostly use in our homes. It is designed for UVB generation for reptiles and turtles. However, its UVB generation isn’t very impressive.
  • Compact fluorescent bulbs: The compact fluorescent bulb has a corkscrew-like shape. The option is ideal for those who don’t have any particular light fixtures for the regular strip fluorescent lights. The compactness of the light limits its reaching capacity and is ideal for small tanks.
  • Mercury vapor lights: If you want a long-lasting light bulb for UVB rays and afford an expensive option, the mercury vapor light is your best buy. The heat generation will come as a bonus with these vapor bulbs. Also, it generates the most UVB light compared to the other two alternatives.

5.00 or 10.00 UVB lights

The UVB rating is another important consideration for turtles, first of remember that both UVB ratings will produce the same amount of light without any exception.

So, what does the UVB rate means?

Well, it speaks of the ability to produce the actual UVB rays compared to the spare capacity. Hence, 5.00UVB has half of the UVB production capacity compared to the 10.00UVB rating of the bulbs.

However, there’s no reason that you must yearn for the larger UVB rating. In fact, the 5.00UVB light is suitable for small tanks and terrariums. I want to recommend the 5.00UVB light for tortoises.

If you don’t have space constraints, the use of 10.00UVB is more suitable for your tank setup.

Wattage Capacity

If you are using a 2-in-1 lighting kit that includes both heat bulbs and UVB rays, the wattage capacity of the bulbs will be crucial. Ideally speaking, the higher the wattage capacity, the higher the heat or temperature production will be of the bulbs.

You will get 25W, 50W, 75W, and 100W lights mostly. The wattage is responsible for the temperature control inside the tank. If you have one or two turtles, getting a lower wattage of the bulb is acceptable.

However, if you have a large tank with multiple turtles, we recommend you get a 75W or 100W capacity for the bulbs.


Although the visible light of the bulbs may still be the same as the first day, the UVB ray generation will reduce over time. It brings the significance of the UVB light lifespan into consideration.

Ideally, most lights will degrade the UVB production after 6 months to 1-year. It will be labeled on the package in hours. So, before making the purchase, read on the label carefully to find out the running time for the UVB bulbs.

Night and Daytime Light

Just like humans, turtles are habituated to the circadian rhythm. So, the turtles have body clocks that regulate their waking and sleeping time.

Ideally, turtles need 10-12 hours of resting time. Henceforth, you need to balance the lighting time inside the turtle tank. The daytime light should be around 10 hours to 14 hours for a turtle inside the terrarium.

So, when you pick a UVB light, you must control the nighttime and daytime emission of the bulbs. I have seen that turtles won’t mind dim brightness even during their sleep time. So, you can choose T5, T8, or LED lights for the day and night light balancing.

Heating Necessity

When it comes to mounting a UVB light with heating capacity, you must know the temperature essential for turtles. At the various stage of turtle life, the adequate temperature will vary.

Turtle Age

Required Temperature

Baby Turtle


Juvenile Turtle


Adult Turtle


Tips on Setting Up the UVB Light

  • UV ray is harmful to human eyes. So, before you start mounting the UVB light in the terrarium, avoid direct eye contact with the light. Alternatively, you can wear protective goggles.
  • When you mount the light, the connection of the socket and lamp must be secure. So, make sure the attachment is tight enough to prevent sticking out of the bulbs.
  • The ideal spot for installing the UVB light is right on the basking spot.
  • Also, make sure the tank is void of any electric connections to avoid any electric shocks.

Frequently Asked Questions (FAQ)

1. What Is The Ideal Light Wattage For The Best Turtle UVB Lights?

You can choose between 50W, 75W, and 100W for the basking light for turtles. The wattage will ardently depend on the tank size mostly. Also, for basking lights, the most crucial consideration is the temperature inside the tank. It needs to be between 75°F-85°F.

2. Will All Turtles Need UVB Light?

Yes, every turtle species will require the right amount of UVB light for its health. The turtle will suffer from the lack of Vitamin D3 without the UVB light. However, not all turtles will require basking ads so, these don’t need heating lamps.

3. When Should I Replace The UVB Light?

Ideally, a UVB light remains efficient for 6 months, although some high-end bulbs may serve for 1-year. So, you need to replace them once every 6 months or 1-year.

Final Notes

The best UVB light for turtles in our review will perfectly meet up the requirements of Vitamin D3 production for turtles and reptiles. Some of these light bulbs even have a heating capacity, which is also suitable for the basking necessity of the turtle.

These light fixtures are durable and easy to install (most have a self-ballast) even for beginners.  With adequate UVB rating and efficiency, these lights will surely keep your turtle and reptile in a healthy and happy condition.
