How to make UV light for turtles?
Many reptiles require UV light to provide the necessary energy for their body. This is especially true for turtles because they are cold-blooded and need to be able to regulate their own temperature.
Reptiles should have access to UV light at all times. But if you do not have a window in your house or apartment that gets direct sunlight, there are other options available.
One way is to use lamps designed specifically for reptiles.
These lights usually produce 3 to 5 watts of UVB rays, which mimic the sun’s rays closely enough for many species of reptiles.
If you’re looking for something more permanent than these lamps, however, it may be easier and cheaper just to build your own lamp using fluorescent bulbs!

What Temperature Is Needed for Turtles?
The best temperature for a pet turtle is between 70 and 85 degrees. A good habitat will have a warm basking area along with a cooler, shaded area where the turtle can get away from the heat if needed.
Is it dangerous for a turtle tank to have only hot water?
No, it’s not dangerous.
Turtles are cold-blooded animals and this means they can’t regulate their own body temperature, so they always need to have a place where they find warmth.
If you keep your turtle tank at the correct temperature, then it’s fine for them to just sit in hot water. That will never harm them.
What Kind of Light Bulbs Do Turtles Need?
UV light for turtles is something that every turtle keeper should think about when they buy a UVB-emitting bulb.
Is it really essential? How hard can you go on wattage? What’s the best way to do it in your setup?
I have been through many of these questions myself, and I looked into what others think about this topic, and to make a long story short, I have created a few very simple, but pretty effective UVB-emitting lamps for my own turtles.
There is no perfect UVB bulb that works for every species and every turtle keeper under all conditions.
There are just too many variables to take into consideration, like differences in room temperature, the size of the terrarium, how much you can move your turtles around, how much time they spend outside the water, how many turtles you have, and so on.
There are, however, a few things that can be said about UVB light, based on years of studies by reptile experts.
First of all, it’s pretty clear that turtles need some form of UVB light to synthesize vitamin D3 efficiently. D3 is the preferred source of vitamin D for turtles, and some experts even say that it’s essential for them to maintain strong bones.
Vitamin D3 is derived from sunlight (UVB light), or more precisely, UVB light combined with dietary fat. Essential fatty acids are needed to transport the vitamin D once it has been synthesized in the skin.
What Will Happen If You Don’t Provide Turtles With UVB Light?
If you don’t provide UVB light, your turtle will not become sick in the sense that it will develop rickets or other bone problems.
However, if you want to keep your turtles in optimal health, UVB light is required for strong bones, healthy skin, and good immune function.
Turtles can synthesize vitamin D3 without any UVB light, but not very efficiently, and some experts say that they really need it. If your turtles don’t get any UVB light at all, their bones will be weaker than they should be.
Another thing to keep in mind is the fact that you don’t necessarily have to buy a commercial bulb for this purpose.
It’s always better to go for the real thing, but you don’t have to spend an arm and a leg either. A regular basking bulb can do the trick, too, as long as it emits UVB light. I will write more about that later on.
UVB light has another interesting property that’s very beneficial for your turtles: It helps to prevent a metabolic bone disease called pyramiding.
I think everyone who has had a basking turtle knows what this is, but for those that haven’t seen it before, pyramiding looks like little mountains on the shell of your basking turtles.
It happens when they spend too much time in the water and not enough time out of it.
Turtles are reptiles, and they need to dry off after every time they go for a swim. This is something that’s very important in order to prevent pyramiding.
The reason why turtles get pyramiding is that their shell grows slower than the rest of their body.
But since water actually weighs more than land, the end result is that land-based areas such as the plastron (bottom shell) and the back grow faster than their weight-bearing areas such as the carapace (top shell).
This causes mountains to develop between their scutes (the plates that make up the shell).
How to Make UV Light for Turtles?
So, how to make UV light for turtles? You need to get your priorities right when you’re lighting up your turtle tank from within.
The most important thing is the actual light output of your bulb.
It’s definitely irrelevant that the wattage matches the actual bulb size and that it’s a Reptisun, Vitalite, or whatever high-quality UVB-emitting brand you want to buy. This is not what makes your turtle healthy!
To be honest, if you just get an older type of fluorescent tube with some filter blue in them (this makes the light emissions bluer) and don’t care about how many watts your lamp emits, your turtle will still be fine.
Now, I’m not saying that you should buy an old-school CFL bulb with some filter blue in it.
While this makes the light emissions bluer, which turtles seem to like better than the natural yellowish sunlight, it’s not enough for turtle health.
I’m just saying that the wattage is not what makes your turtle healthy in the end, but you need to get that wattage right when buying a new lamp!
If you’re starting out with this lighting thing for turtles, always buy 10% more than the highest recommended value for your species of turtle.
To give you an example of that, for a red-eared slider, it would be about 10% over the 30W mark, maybe even 20W if you have some pretty big specimens.
I’ll go through the steps you should take when buying a UVB-emitting bulb. If you have enough lamps in your tank already for some reason, do not buy one light specifically for this!
This will create far too much of a temperature difference between the basking zone and everywhere else, which will give your turtles all sorts of health problems. However, if you already have the lights in your turtle tank, do not remove them!
Now, let’s say you want to buy a new UVB-emitting bulb, and we always want to aim for the highest wattage we can get.
There are 2 types of these bulbs: T8 and T5 lamps. The T stands for Tube and the number tells us how many times the diameter is cut in half (so a T8 has a diameter that is 8 times smaller than a T12 lamp, while the T5 has a 5 times smaller diameter). The T12 lamps are usually around 24 to 28W and the T8s are from 10 to 20W.
But these wattages can also be different if they’re older or newer lamps.
Conclusion
Finally, to make UV light for turtles, you will need a fluorescent or LED lamp. Place your lamp at one end of the enclosure and provide hiding places for the turtle to get away from it when they want to escape.
When designing an indoor setup, be sure that there is enough room in front of the heater so that the turtle can bask under its heat source without being too close to any other sources of warmth such as lights or filters.
After making these preparations, place your new pet in their habitat and enjoy watching them swim around!
