      Best UVB Light for Turtles – FAQs

      What is the best UVB light for turtles?

      There are plenty of factors that go into deciding which the best UVB light for turtles is. The best one for you will depend on the size of your tank and how you’re going to be able to install it. All the lights we’ve looked at on this list are high quality and you can’t go wrong with any of them.

      What kind of UVB light do turtles need?

      Not all turtles are the same and some need more UVB light than others. Usually around 2.5% – 5% of UVB light for aquatic turtles. If you use a 10% UVB lamp then ensure it’s safe for your turtle and also keep it at the appropriate distance.

      Can turtles get too much UVB?

      You don’t want to overload them with UVB as it could then start to cause some skin issues. You can give them long breaks away from the UVB and also a shaded spot away from the light for when they don’t want to bask.

      How many hours of UVB do turtles need?

      You want your turtle to have a full day of sunshine. That means giving them up to 12 hours of UVB light. This is especially important if they aren’t getting much natural sunlight. This also means you can switch the light off for long periods.

      How many watts should a turtle light be?

      Wattage used to be a good measurement of light intensity but it’s less important now. For a traditional bulb in a large tank, 50w could be the perfect size but if you’re keeping your light close in a smaller tank then 25w may be all you need. LED bulbs, however, need a lot less power for the same performance and 3 watts may be all you need.

      Do you turn off UVB light at night?

      As we mentioned before, a turtle will need to be under a UVB light for around 12 hours in a day. Due to that, it makes sense for you to turn the light off at night time. This will have on electricity and prevent over exposure. Many people will use a timer to make light changes as simple as possible. 

      Do turtles need UVA or UVB?

      They will need both UVA and UVB light. As we mentioned, UVB is essential in the production of calcium and giving them the best bone and shell health. UVA is important at too as they will need this to stay active, improve their mood and eating habits. For reference, UVC is harmful to turtles and should not be used.

      Does a UVB light give off heat?

      Turtles need UVB and UVA light for their bodily functions but they also need to bask in heat to kill bacteria and dry out. Some UVB lights give off enough heat so that the turtle can bask in it comfortably. Other turtle owners prefer to get a separate basking light.
