Chameleons are some of the most amazing reptiles, between their vibrant colors, unusual eyes and adorable feet; however, they are some of the most challenging reptiles to care for properly.

They should be considered advanced reptiles and should be adopted by people who have a good deal of experience caring for other reptiles.

One aspect of chameleon care that can be particularly tricky is finding the right lighting. Chameleons need both UVA and UVB light. UVA is within their visible light range and without lighting in that range, they may have effects to their normal behavior and physiology.

UVB is vitally important for normal production of vitamin D3. Without D3, they are unable to properly absorb and utilize calcium, a mineral essential to good muscle function, bone strength, proper nerve function, and a healthy immune system.

What To Look For In UVB Bulbs For Chameleons

Choosing the right cage for your chameleon is important because these reptiles have specific needs. Because they are arboreal, they need lots of vertical space to climb.

On top of that, they need proper heat, humidity, and lighting. When it comes to lighting your chameleon cage, you’ll need to include UVB lighting and that requires a special bulb.

Here are some important things to look for in chameleon UVB bulbs:

  • Type – There are many different types of lighting available for pets. The balance is found between cost, size, and light output. Some will also provide heat, while others require a second source for heat.
  • Fixture – When shopping for UVB bulbs, consider the type of fixture required and purchase according to the type of lighting that’s best for your cage setup.
  • Rating – Light bulbs for reptiles are rated for the percentage of radiation emitted in the UVB range. The rating system varies by company. Generally for chameleons, the UV rating should be in the middle range. Most companies have guides to help you select the proper bulb and the distance it should be from the basking site.
  • Size – On top of choosing the right percentage rating for your chameleon cage, you’ll also need to choose a bulb the right size. Consider the type of fixture you have and the type of cage you have to determine where you can mount the fixture for the greatest benefit.

Now that you have a better idea what to look for in a chameleon UVB bulb, it’s time to start shopping! Keep reading to see our top 5 picks for the best chameleon UVB bulbs.

Tips For Lighting A Chameleon Cage

Chameleons are arboreal creatures, so they require a cage that is taller than it is wide to accommodate branches for climbing. They also need the cage to be kept warm and humid with several areas for basking.

On top of heat, humidity, and basking areas, you also need to provide the right lighting. Chameleons require proper lighting to be able to absorb the calcium that keeps their bones strong.

Here are some simple tips for lighting a chameleon cage:

  • Choose a fluorescent bulb that provides both UVA and UVB light – keep in mind that most broad-spectrum bulbs do not produce UVB light.
  • Consider which type of lighting to choose. Fluorescent lights don’t produce heat, so they can’t also function as a basking lamp. Mercury vapor bulbs do, but they are more expensive.
  • Place the lighting in a way that your chameleon will get the exposure it needs at the top of the cage in a comfortable basking area.
  • Keep the lighting system on a cycle with 10 to 12 hours of exposure per day.
  • Pay attention to the lifetime of the bulbs you purchase – they may lose strength over time, so swap them out every 6 months or monitor the strength of the bulb with a UV light meter for guidance. The UVB spectrum will taper before the light stops coming on.

To determine the best lighting system for your chameleon, you need to research the species you plan to keep and find out the specific requirements. The companies listed above have helpful charts on their websites to determine how far above the basking area to mount your bulb for the species.

Now that you understand the basics of lighting a chameleon cage, you can see how UVB lighting fits in. Choosing the right UVB bulb is important because your chameleon won’t get what it needs without one.

Final Remarks

Chameleons make wonderful pets, but they can also be fairly challenging to keep. On top of choosing a cage with the right dimensions, you also need to provide for your chameleon’s needs for proper temperature, humidity, and lighting. When all of these things come together, you’ll have a happy and healthy chameleon. Don’t forget about UVB lighting!
