The Ultimate Bearded Dragon Lighting Guide

bearded dragon lightingSetting up a terrarium for your dragon can be very hard if you are a beginner. It is very important that you get the right bearded dragon lighting, but especially lighting is a very complicated topic for beginners. You need the right temperature, UV radiation and so on and so forth.

Before you start reading I want to point out that this is the lighting I recommend, I do not say, that this is the best lighting in the world or whatever. All I say is, that I had a positive experience with the lights I recommend.

What you are going to learn from this article

  • How to choose the right light for your dragon.
  • How to get the right temperature.
  • How to choose the right UV Lighting
  • Further I am going to show you what lighting I use and where you can buy it.
  • What you should not do!

You need light!

There is one mistake most people make when it comes to reptile lighting: They think that that every lighting will spend light and warmth. However that is not the case. Not every lamp will provide warmth and a lot of lamps which provide warmth do not really provide enough light.

However it is extremely important for bearded dragons to get enough light. Why? Well they are from Australia, they are used to get a lot of light and you should always try to create a habitat which is very close to their natural habitat in Australia.

Light stimulates their appetite and it is very important for their mental well-being. Further it should be white light, since bearded dragons do not so well with other types of light. I will show you below which light I use for that.

So other than Hugh Jackman, bearded dragons can´t get too much light.

Get the right UVB Lighting!

Okay I do not want to go too deep into this topic, because in my opinion this can be a very dry subject.

However you should know that bearded dragons need UV lighting to stay healthy. If they do not get UV lighting it will have an huge impact on their behavior and on their mental well-being and they will get sick.

Providing the right UV light prevents metabolic bone disease. It promotes the synthesis of Vitamin D3. Without that, their bones will become soft and that will cause deformation of the bones and so on and so forth.

Sounds ugly, huh? It is!

So here is the lighting I recommend for that plus the fixing, which you are also going to need.

This lighting does not only provide UVB, it also provides a good looking white light and as I said, you wanna make sure that your bearded dragon gets enough light.

And I am not the only one who thinks that the Repti Sun is awesome. This product has 121 customer reviews on Amazon and it has a rating of 4.5 out of 5 stars. Do I need to say more?

This is one of the few UVB lights I really recommend. I would not go with another light than this. The reason for that is very simple. There are UVB lights which cause I problems on bearded dragons, needless to say, that I would never recommend those lights. I do not want to tell you the name of the manufacturer here, because I do not want to get in trouble.

Simply get the Repti Sun, it is a really good UVB light and it is very cheap in my opinion. There are other UVB lights which cost $50 or more, the Repti Sun is much cheaper.

Get the right temperature!

If you want to get the right temperature, you have to know what temperature is good for your dragon. The average temperature in your tank should be around 78-88°F during the day and around 70°F at night.

Besides that you need some very hot spots. Bearded dragons like to lie in the sun on huge stones. Especially in the morning, since they need to get the right body temperature. Those hot spots should have around 95°F – 105°F …yepp that´s hot! Your bearded dragon is black all day? Your temperature might be too low!

You do not have to buy very expensive reptile heat lamps for that. In fact normal heat lamp from the DIY market is okay. I recommend to go with 100W, but it depends on your tank size. You can also regulate the temperature by hanging the heat lamp a little higher above the tank.

So you can simply use this normal 100W light bulb from Amazon here plus clamp lamp to place it on your terrarium and of course a thermometer so you can see if you get the right temperature. I recommend to go with the ReptiTemp here. Simply point and click to check the temperature 🙂

Beside warmth, the light bulb also provides a lot of white light, which is excellent. Besides that it is very cheap.

Why I do not use any reptile heat lamps

There are some good reasons to not use all the reptile heat lamps out there. If you search heating lamps for reptiles in Amazon, you are going to get tons of results for that.

In my opinion, most of those lamps are very bad. First of all they are really expensive. Especially beginners are afraid of doing something wrong and rather take a reptile heat lamp than a normal 100W light bulb. Do not spend your hard earned money on overpriced products like those reptile heat lamps.

Secondly those heat lamps are known for being very short-lived. Many people on Amazon say that those lamps only last a few weeks. I think that is ridiculous.

So, don´t be afraid, just take the normal 100W light bulb with the clamp lamp and everything is going to be alright 🙂

What you should know

Bearded Dragon Lighting Facts - More Info On BeardedDragonTank.comThe UVB output of those lamps will decrease over time. I recommend to change the UVB lights every 6 months.

Dragons need 12 hours of light

Bearded dragons need light for around 12 hours, turn the lights off at night. Please make sure that the temperature at night is not below 65°F. That could cause health problems.

Do not use coil lamps

I do not recommend that you use any coil lamps for your terrarium. It is known that those coil lamps cause eye problems for example. I stay away from that completely, no matter if it is a heating lamp, or if it is a UVB lamp.

i have a 40 gallon tank so what size reptisun light do i need and should it be a 10,0 or a 5.0? Ty.

    Pierre

    Hey Sharon,

    it always depends on the length of your tank. Since you have a 40 Gallon tank, you should definitely go with a slightly longer bulb.

    Try the lighting bulb in this article here: Lighting for a bigger tank.
    Simply scroll down a little bit, you will see a 10.0 with a different length I recommend there.

    If that´s too long for your tank, you can also simply use the bulb I recommend in this lighting guide.

    Hope this helps Sharon!

    All the best,

    Pierre

So my son and I have gone for all of your recommendations and are upgrading to the kit you recommended. I have a couple of questions: do you not use the purple light at night? How do you keep the tank at 65 degrees at night – just keep the room that he is in at that temp? How do you clean the substrate?

Thanks!

    Pierre

    Hey Beth,

    a lot of people use infrared lights or something like this at night, but I do not really like that. It is not only that I do not like infrared lights for my beardies, I am also worried about the electricity bill.
    Yes I keep the room where the tank is in at 65 degrees at night. For me it´s easy to do.

    Regarding the substrate… it depends on which substrate you have. Do you have the substrate from my substrate article? Then it is easy, simply take a shovel and remove the poop. Sometimes I take a toothbrush with a little bit of water and clean the remaining dirt.

    If you have loose substrate (which I do not recommend!!), removing the poop with the shovel will do the job.

    If you have the reptile carpet, remove the poop with a shovel. Further you should wash the carpet with warm water and a little bit of soap. Do this one time per week or two time per week. It always depends on how much your dragon poops. 🙂
    Please make sure that you wash out the soap completely!

    Let me know if this helps, Beth 🙂

    Cheers,

    Pierre

Beth

Thanks Pierre. I got the substrate you recommended in the article. This is our first dragon and I want him to be happy.

    Pierre

    Hey Beth,

    good to hear that, with that substrate you can build your dragon a really good looking and a very natural home.
    Ah the first one is always special. If you have any questions or any problems with your dragon, just comment here on my website and I will be there for you, Beth!

    Have fun 🙂

Hello,
i have a 30″ long 18″ tall tank. I ordered the Zoo Med T5 HO Reptisun Terrarium Hood 24″, but im still looking around for a cheaper alternative. Could i use a regular light fixture like the one you have listed for a T5? And what length do you think i should get? Thanks!!

    Pierre

    Hey Jaime,

    for your tank size you can use the exact lighting + fixture that I recommend in this article. The bulb is 18″ and the fixture is 21″ in total, which means you still have enough space to also put a heat bulb on top of your tank.
    You can use the fixture for a regular T8 🙂

    Hope this helps Jaime!
    If you have any further question, just leave me a comment and I will be there for you.

    Cheers,

    Pierre

      Jaime

      Thanks! So i would have to mount it inside of the cage, yes? And the fixture says its 18″ or 22″, so i should go for the bigger one?

        Pierre

        No problem at all Jaime 🙂 You are very welcome!

        I would suggest to mount it on top of the cage. Do you have a screencover for your tank?

        Sorry Jaime, I had a closer look at the fixture I recommend above and it is actually a fixture for T8 bulbs. So you can absolutely use this fixture above if you buy it together with the Repti Sun 10.0 which I recommend above. This Repti Sun is an 18″ bulb which is absolutely fine for your tank size.

        So at the moment your fixture is longer and it fits the 24″ bulbs. If you really want to switch to the less expensive fixture, you´d have to buy the smaller 18″ bulb also.

        However I have to say that all of those articles are the best when it comes to reptile lighting, so you can´t really make a mistake here.

        So it is totally up to you, switch to a shorter bulb with a less expensive fixture and you will be fine.
        Or stick with your more expensive fixture and the longer bulb which is also absolutely fine 🙂

        I hope this helps Jaime and I hope I did not confuse you now. If I did, please let me know and I´ll explain it again 🙂

        Cheers,

        Pierre

Danielle

We have a 40 gallon tank. Would you recommend mounting the reptisun inside the tank, hang from the top of the lid along with the basking light or is it better to have on top of the cover? We have other pets that I worry may knock off the lights if on top. What size lights should we get for a 40 gallon tank? Obviously we are new to this and the lighting seems to be very important so I want to get it right. Also, at what age do you introduce the clay that you have in your articles?

    Pierre

    Hey Danielle,

    lighting is definitely very important!

    The UVB bulb might be too near to your bearded dragon then, so I would not recommend it.

    For a 40 gallon tank, I recommend to use the lighting in this article.

    Cheers,

    Pierre

Samantha

Hi, I have a 36″ x 18″ x 18″ terrarium. I was wondering if the 36″ Reptisun T5HO tube would be okay for my bearded dragon? I keep getting mixed responses, some say it should be 2/3 and some say should cover the length of the terrarium. I am just confused because there is a lot of biased information out on the web. What is right light to get? :O

    Pierre

    Hey Samantha,

    sorry for my late reply, I was on vacation.
    If you have a 36″ tank and your uvb bulb is 36″ as well, the fixture for that bulb is going to be bigger than 36″ and that might look a little bit weird on your tank.

    Regarding your mixed responses about the length of the uvb bulb: 2/3 is fine, however the full length of the tank is okay as well. You just have to make sure that the UVB bulb has enough distance from your beardie. Further you should have 1-2 hides for your little dragon.

    Personally, I use a bulb that is around 2/3 of the tank.

    Cheers,

    Pierre

Hi. I live in Arizona. It’s summer and 110 dregrees outside. Do i need to use a heat lamp uva if i dont air condition my the dragons room? What is the red light for? And i do need the uvb on the day, right? Hes by a window. Im going away for 10 days and he’ll be babysat. How do i instruct the babysitter when I’m so unsure myself. The adult dargon was recently given to us with all the lights.

    Pierre

    Hey Sara,

    wow, that is hot!
    You should have a basking spot, but you probably can choose a lower wattage to get the right temperature.
    The red light can hurt your bearded dragon, so I would not recommend to use it.

    I would not place the tank in a spot with direct sunlight. The tank can overheat and your dragon could die.
    Further it makes no sense, since the UVB can´t get through glass anyway.

    Hm the question is: Do you have the right lighting? Do you have a time switch so that the babysitter doesn´t have to take care of that?
    You should take care of that first. This article will help you with that. Keep in mind that your beardie should get 12 hours of sunlight.

    If you have that, you only have to tell your babysitter to feed your dragon correctly. My Beardie Care Guide will help you as well.

    Regards,

    Pierre

I can’t tell if your UVB light is 5.0
or 10.0. What do you recommend for a 40 gallon tank putting the light in top of the screen?
Thank you,
Tiffany

    Pierre

    Hey Tiffany,

    it is a 5.0. The bulb I recommend in this article should be absolutely fine for your tank 🙂
    Cheers,

    Pierre

Renee Killis

I will be away from my Beards for 5 days. I will leave food and water for them. I have a 40 gallon tank and I keep the white light on the far left side. Would it be ok to leave the light on for 5 days? The Beards go to the other side and hang out there where it is dark. Is it necessary to turn off the white UV light and turn on the red light daily? The Beards are 6 months old. Their light is on top of the screen. It is a round light. Thanks!

    Pierre

    Hey Renee,

    sorry for my late reply, I was on vacation.

    I hope that you did not let your bearded dragon alone for 5 days 🙁
    Beardies have normal day/ night cycles like we do. Leaving the light on permanently will kill your dragon 🙁

    Keep the lights on for 12 hours a day.

    Hope your dragon is okay!

    Pierre
