Our List Of The Best UVB Lights For Your Bearded Dragon
Fortunately, a lot of the best UVB lights are well-known in the herp community. We’ve actually crossed paths with many of the ones below before we started to do research for this list!
With that being said, we still approached the research process from square one. We challenged our assumptions about bulbs we liked, and entertained products we hadn’t used before.
We also sourced great feedback from the community to help pull in even more information!
After a while, the clear winners emerged. We’re quite happy with our list of recommended UVB lights below, and think you’ll find great success with them!
1. UVB High-Intensity Self-Ballasted Light For Bearded Dragons By TEKIZOO
Right off the bat, we have a great UVB light that’s been around for quite a while. The manufacturer has a great track record, and we’ve used their products before.
- Provides strong and consistent UVB and UVA for reptiles
- Bulb is compatible with a variety of enclosures
- Compact size of 6.3 x 4.5 inches
- Bulb undergoes strict testing before being packaged
The nice thing about this bulb is that it’s UVB as well as UVA. This allows you to cover all your bases with a single bulb. Your bearded dragon will receive all the benefits of natural sunlight!
One of the things we really like about this light is how versatile it is. You can use it with a wide variety of enclosures (tanks, vivariums, cages, terrariums, etc.) which means you don’t need to worry before buying it. Some lights need a very specific mount in order to work, but that’s not an issue here.
The reviews of this UVB light are great and plenty of owners vouch for the reliability and safety factor. This is an area we take very seriously, so it’s been great to see that we’re not the only ones with this opinion.
The dimensions of this lamp are 4.5 inches wide and 6.3 inches long. This is relatively compact which is partly why it can be used with so many different setups.
- Both UVB and UVA
- Can be used in a variety of enclosures
- Fantastic build quality
- Needs very specific positioning in order to spread light
2. Reptisun 10.0 UVB Compact Fluorescent By Zoo Med
This is, without a doubt, one of the most popular UVB light options for bearded dragons. Zoo Med is a company that’s been in the game for a while and has a reputation for making high-quality products.
- 10% UVB output & 30% UVA output
- Uses a special UVB transmitting quartz glass for maximum UVB penetration
- Can be oriented either vertically or horizontally
- Perfect for all desert and basking reptiles
The Reptisun was actually the first UVB light we got for our bearded dragon. While there are a couple different variations of this fluorescent lamp, we decided to review the compact version due to the flexibility it affords.
With the compact build, you can make it work no matter what kind of habitat setup you’ve created. They’re only 6 x 2.6 inches, which gives you some options. You can even use a few of them if you have a really large space (although their larger version would work as well).
These lights are built quite well and feel well-made when you handle them. They have quartz glass which aids the process of UVB penetration quite well, and won’t easily break.
You should get a lot of use out of them (around 4-6 months) which is not bad at all. This is especially true when you consider that you’ll likely be changing them out around this time regardless if they’re still working or not (more on that later).
- Well-designed compact build
- Reliable and durable
- Great UVB output
- It’s best to go with their larger version if you have a big tank
3. Compact 70 Watt Mercury Vapor Bulb By Mega-Ray
Even though this is one of the best UVB lights for bearded dragons, we think it doesn’t get the attention it deserves. While the other products on our list are obviously great choices, the lack of interest in this product by Mega-Ray is a bit confusing.
Pound for pound, we think this is one of the most efficient and powerful bulbs you can get. It’s only 4 x 4 inches and weighs just under 5 ounces!
- Bulb offers best in class lifespan
- Smallest and most compact design on the market
- Provides essential UVA and UVB light
- 100% satisfaction guarantee
But despite that, it just works. This light has great UVB output (it handles UVA as well) as long as you place it in the optimal position.
Tons of owners have reported a noticeable improvement in the health and activity of their bearded dragons when using this light. Many we spoke to swear they’ll never use another UVB bulb again!
The one downside to this bulb is it doesn’t seem to be as durable as some of the other options out there. While we think the positives outweigh the negatives, it’s worth considering if you don’t want to risk replacing them.
As long as you read the instructions and install it at the right distance/position, we think you’ll be very happy with this light.
- Best pound for pound output
- Compact design allows you to use it in many different ways
- Not as durable as some of the other bulbs on our list
- A bit more expensive
4. Bearded Dragon UVB Fluorescent Bulb 18 Inch By Zilla
This is a great longer-style UVB light for your bearded dragon. In our opinion, this should be one of the bulbs you consider if you don’t want one with a compact design.
- Provides powerful and consistent UVB/UVA lighting
- Full spectrum lighting enhances natural colors of the animal and environment
- Bulbs designed to fit most major fluorescent fixture types
- Designed for 3500 hours of use
This product has a great light output that you can rely on. It also provides full-spectrum lighting that helps bring out the colors of your bearded dragon and the rest of its habitat.
The amount of use you can get out of this bulb is really impressive as well. It’s definitely one of the longer-lasting lights on our list, with the company claiming you’ll only have to replace this every 12 months!
During our research process, we found a variety of longevity claims from owners, but they average out to be quite long (much longer than 6 months).
You can fit this light in most of the major fluorescent fixtures, so the main factor to consider is the size of your tank. If you have a tiny tank then you’re probably better off with one of the compact options just for the sake of convenience.
Many owners have reported that using this UVB light has brought out a whole new level of activity in their bearded dragons. We didn’t notice this as much, but that’s likely because the lighting situation before was pretty solid.
- Best long bulb on the market
- Great for enhancing colors
- Length limits the kind of tank you can conveniently use it with
5. 100 Watt UVA/UVB Mercury Vapor Bulb For Reptiles By Evergreen Pet Supplies
If you’re looking for a high-quality UVB light that your bearded dragon will thrive in, this bulb by Evergreen Pet Supplies is a great choice. Out of all the lights on our list, this one had the most feedback (and it’s great).
- Powerful and effective source of UVA/UVB/visible light
- Completely self-ballasted

- 3-step test conducted on each light to ensure proper working condition before shipment
This is a dual-threat light that covers your UVB and UVA requirements. It will do a fantastic job of keeping your bearded dragon healthy and enriched with the necessary vitamins they need to stay healthy.
One of the nice things about this bulb is that it can be used with a wide range of different enclosures. It doesn’t matter if you’re using a tank, vivarium, terrarium, or any other option. This bulb can be mounted without any problems.
We really like the reliability background that this light has. Evergreen does a great job with this by running a handful of tests on each of these lights before they ship. This weeds out any potential defects or safety issues. They also make sure it’s backed up with a top-notch warranty in case you run into any issues later on.
- Reliable and safe
- UVB and UVA
- Compatible with many different enclosures
- Not quite as compact as some of the others
The Importance Of UVB Light For Bearded Dragons
Before we jump into the list, it’s important to explain the importance of having a UVB light if you have a bearded dragon. In our experience, many new owners know they should get a UVB bulb, but they’re not sure why.
Here it is:
UVB light helps your bearded dragon synthesize vitamin D3 from vitamin D. By doing this they’re able to absorb calcium and maintain their bone health.
If your bearded dragon doesn’t get enough UVB light each day, their health will ultimately fail. It can even lead to other conditions like tail rot.
Unlike UVA light that is emitted from basically all standard bulbs, UVB needs a specialized source of output. That’s where the UVB bulb/lamp comes in.
Because this kind of light is so important, you want to make sure you’re using a trusted and reliable bulb. Low-quality bulbs will generate an inconsistent or inaccurate amount of UVB light, making it harder to maintain the health of your bearded dragon.
Now that you know what the best UVB lights for bearded dragons are, it’s time to dig into the details a bit. You see, there are a few things you need to know about proper UVB usage to ensure your pet fully benefits.
Create A Schedule For How Much UVB Time Your Bearded Dragon Gets
This is a question we receive a lot from new owners purchasing their first UVB light. They know their bearded dragon needs it, but they’re not sure how much light they should actually give them!
Fortunately, the answer is pretty simple.
Since bearded dragons don’t need this light at night, you can turn it off when it’s time to go to bed. Aim for 12-14 hours per day with the light on, and the remaining time with it off.
Pretty easy huh?
The most important thing to do is to make sure they have some room in their enclosure where they can get out of the light if they choose. As long as you position the light properly and give them a shady spot, you’ll be just fine.
Figure Out The Ideal Wattage
As you probably saw, there are a few common options for wattage when it comes to picking a UVB light for your bearded dragon.
This might cause some confusion if you’ve never purchased one of these before (or if you’re a new owner in general). But thankfully, the solution to this problem is actually quite painless.
While wattage obviously impacts the strength of the light, it’s actually the least impactful factor! Instead, focus on getting a bulb that fits your enclosure.
The things that impact how powerful the light shines on your bearded dragon are placement (how far away it is from them), if there are any objects or screens in front of the bulb, and if you’re using any reflectors.
Set Up The Light Properly
As we hinted to above, the placement of your UVB light is by far the biggest influencer in how much light your bearded dragon received on a daily basis.
The general rule of thumb if you’re using a standard bulb is to find a mounting spot 7 to 10 inches away from the basking area your pet will be using. It’s important to be providing enough light when your bearded dragon wants it, but also give them a shady spot to hide if they need a break.
If you’re using a mercury vapor bulb you need to take a different approach. Normal strength mercury vapor bulbs should actually be on the outside of the enclosure (roughly 3-4 inches away from the cover).
If the mercury vapor UVB bulb you’re using is quite powerful then you’ll need to increase the distance between it and the cover of the enclosure.
The number of times you need to replace your bulb is obviously quite important since it will impact overall cost and convenience.
Most reliable UVB lights that you’ll be using for your bearded dragon will get anywhere between 5 and 12 months of use before they stop working.
However, we recommend that you swap them out twice a year anyway. Even though some bulbs can last longer than that, their efficiency and output will often start to suffer after this point.
Instead of risking the health of your bearded dragon, stick to a schedule of changing them out before they become a problem.
Why You Should Stay Away From Coil UVB Bulbs
While it’s not common, we sometimes get questions about coil UVB products from new owners. They’re not found or recommended often (for good reason), but you will bump into them from time to time.
But you should stay far away from them.
The reason they’re not ideal for a bearded dragon is these bulbs have a very high output. Not only are they too powerful, but the output can also be inconsistent.
This can cause serious health complications for your bearded dragon. Damaged vision is most common, but there are other problems that can manifest when given enough time as well.
Simply put, stay clear of coil bulbs and stick with the lights we included on our list.
It’s Time To Pick One Up
Now that you know a bit about each of the best UVB lights for bearded dragons, all that’s left is to pick your favorite!
No matter what kind of enclosure you have, at least one of the products above will fit your requirements.
Remember to think about convenience, reliability, and safety above all else. Also please follow the included instructions to ensure that everything is mounted properly (you don’t want any accidents).
UVB light is one of the most important pieces of the lighting puzzle when it comes to this animal. Take this purchasing process seriously, and your bearded dragon will thank you for it!
