Best Basking Bulb For Chameleons

Do you want to set up your Chameleons habitat just right so it lives a healthy life?

Are you worried about keeping your Chameleon’s cage warm enough?

As we all know, the correct habitat set up is key for Chameleons health.

One of the important parts of this set up is the basking spot.

The correct temperature for this spot is essential for the cold-blooded reptile to help regulate body temperature.

With so many options out there, it’s hard to find the best basking bulb for a Chameleon.

Good basking bulbs should be at least 75 W and produce enough heat to get the basking spot up towards 95° degrees Fahrenheit (35° C). Our picks for the best basking bulbs are:

Check out the rest of the article for more details.

What Is A Basking Spot?

A basking spot, when it comes to reptiles, is a place in the cage where the reptile will go to raise its body temperature and soak in extra UVB radiation.

Cold-blooded reptiles, such as the Chameleon, don’t regulate their body temperature internally as we warm-blooded creatures do.

They need external forces to help them heat up and cool down.

The heating up is especially important.

Higher temperatures help with digestion, activity levels, and overall health.

For this reason, you must have the correct set up for a basking spot.

What Makes A Good Basking Spot For Chameleons?

The exact requirements depend on your species of Chameleon, but there are some general guidelines you may follow.

The basking spot temperature should be kept between 85° to 95° degrees Fahrenheit (29° – 35° C) in the daytime.

There needs to be a single heating lamp pointed at this spot.

6″ to 7″ inches (17.78 cm) above the spot is a good goal for placing the basketball.

The temperature of the spot should be checked with a general thermometer or, better yet, using an infrared spa checking thermometer such as this one by Etekcity.

The reviews below focus on the basking heating bulb.

However, there also needs to be UVB lighting at the basking spot.

UVB lights provide radiation similar to the sun which provides the Chameleon vitamin D.

This vitamin B is needed to help absorb calcium.

In captivity, Chameleons need calcium in order to avoid diseases such as metabolic bone disease.

A good UVB bulb should provide 5 to 10% output and reach at least 12″ inches (30.48 cm) in its penetration.

In some cases, such as with mercury vapor lights, the lamps may provide both heat and UVB.

These bulbs will save you effort, but they often cost more and have shorter lifespans.

Wattage/Heat Output

The first and most important element of a basking bulb is how much heat is put out.

Know the wattage required depends on the type of bulb you are using.

A good rule of thumb is to look for a basking bulb at least at 75 W.

Getting a bulb with these specifications will provide enough heat for the basking spot.

Less than 75 W and your light won’t produce enough heat to get the basking spot up to the required Temperature.

Higher than 175 W, and the basking bulb will provide too much heat and could burn your pet.

The exception is with the double duty mercury vapor bulbs.

They need a higher wattage to provide both UVB and heat.

With these, it’s OK to go up higher.

Just make sure you spot check the temperature with this bulb as well.

Heat Range

In most cases, basking bulbs either provide a spot of heat or general heat.

Either one works just fine for a basking spot, but those which provide a wider range of heat may also heat your cage up to the appropriate amount.

On the downside with these wide range ones, they sometimes won’t provide enough heat at the specific spot.

Always make sure to check the temperature with any bulb you buy.

Whichever type you buy and whatever range they have, make sure the bulb’s placed 6″ to 7″ inches (17.78 cm) above where the basking spot is.

Any closer and you could run into some problems.

The Chameleon may end up touching the bulb and get burned, or the heat is just too close to the basking spot in your Chameleon will get overheated.


Lights, whether UVB or heating, are one of the recurring costs of owning a Chameleon.

Heating lights, such as those used in basking spots, tend to have a shorter lifespan.

In the worst cases, the last about two weeks.

In general, the best basking bulbs may last up to two months.

When you read the reviews below, check out how long each bulb lasts and balance it with the cost.

Socket Requirement

Since heating lights provide a lot of heat, they also store a lot of heat in their bulbs.

Where they connect to a socket can get really hot depending on the brand and design of the bulb.

Be sure to check what the manufacturer says the bulb needs for a socket.

In many cases, a heating bulb will need a ceramic socket to connect to.

The ceramic handles the higher heat better without cracking or melting.

Porcelain is another common option, but this one doesn’t tend to work out as well.

Some bulbs are self-ballasted which means they provide an extra piece to absorb the heat between the bulb in the socket.

This doesn’t always work effectively, so make sure to check with actual users who have said in their experience.

Fluker’s Basking Spotlight Bulb 100W

Fluker's Basking Spotlight Bulbs for Reptiles,100...
  • Directs heat and light toward a specific area for basking reptiles
  • Package Dimensions: 14.224 H x 4.572 L x 7.874 W (centimetres)
  • Package Weight: 0.018 kilograms

Fluker’s is a well-respected brand in the reptile world.

This affordable bulb comes in a variety of sizes to meet the needs of different reptile cages.

Look for different bundles including the following:

  • 2 pack
  • 60 W
  • 75 W
  • 100 W
  • 150 W

For Chameleons, the best choices are 75 W and 100 W.

This will heat up the basking spot and much of the rest of the cage also.

Higher than this is also an option.

A higher wattage will heat the whole cage and save you some time, but you increase the risk of burning or overheating.

However, keeping the lamp outside the cage pointing in and moving the bulb a little farther away should go a long way in fixing this problem.

Fluker’s light here is a spotlight option. It directs most of its energy and heat in a narrow path.

This keeps your basking spot right where it needs to be without losing its efficiency.

The light is bright, but the color of the light is warm, so you won’t be blinding when looking at your pet.

Depending on the wattage selected, expect to use a ceramic socket to avoid burning out the lamp it’s in.

The light heats through infrared heating which is usually more efficient and effective at heating up reptiles.

Pros For This Product:

  • Great value
  • Lasts for 1-2 months
  • Different wattage options to meet your tank needs

Cons For This Product:

  • May arrive broken (but is quickly replaced)
  • Bulb gets quite hot

Zoo Med Repti Basking Spot Lamp 150W

Zoo Med’s medium-priced spot lamp 150 W option is perfect for those who want to make sure the basking spot gets to the right temperature or has a larger cage.

This 2-pack actually comes in at a medium price per bulb.

This bulb was designed with desert and tropical reptiles alike.

Hailing from the tropical rainforest as Chameleons do, this makes it a solid choice for your pet.

Zoo Med uses its special double-reflector design in this bulb.

This increases the heat on point and energy-efficiency of the bulb beyond other comparable bulbs.

The company claims a 35% increase over its competition.

While we haven’t measured the exact energy-levels, we’ve seen efficient heating with this powerful 150W bulb.

This bulb may be placed outside the Chameleon cage pointing in and still be powerful enough to work.

As a plus, this light is also powerful enough to use with other reptiles such as bearded dragons who require an even higher temperature.

You’ll definitely need a ceramic socket with this higher energy bulb.

Anything less will burn out your lamp.

Pros For This Product:

  • Good value
  • Powerful heat
  • Energy efficient
  • Lasts for 1-2 months

Cons For This Product:

  • Hard on sockets
  • More likely to blow when handled by bare skin (use rubber gloves to avoid oils from your skin)

Zoo Med Repti Basking Lamps 75W

Zoo Med Repti Basking Lamps 75 Watt (4 Pack)
  • Spotlight lamp for focus on defined areas
  • The Reptile Basking Spot Lamps have a unique patented double reflector
  • UVA output

This is a more moderator (and affordable) bulb option for Chameleons.

Basically, Zoo Med took the same double-reflector design from above and lessened the wattage.

With this bundle, you get 4 bulbs at a much lower price per bulb than either product on our list.

75 W is more in line with what a standard size Chameleon cage will need.

This wattage will heat the basking spot well when placed 6″ – 7″ inches (17.78 cm) above the spot.

Unfortunately, it likely won’t also heat the rest of the cage enough.

You may need to look into an additional heating element such as a heating pad or heating rock.

At lower power, this bulb doesn’t get as hot and won’t require as much of a special lamp to use as the higher wattage options.

The life of these bulbs tends to be higher than other, more powerful, options.

While 1-2 months is a good range, this one definitely sticks close to the 2 months (or a little longer) mark much more consistently.

Pros For This Product:

  • Excellent value
  • Provides enough heat for basking spot
  • Lasts 2+ months
  • Not hard on the lamp sockets

Cons For This Product:

  • Won’t heat the rest of the cage as well

Commonly Asked Questions

Can I use a regular bulb as a basking light? – No, these lights won’t produce enough heat directed at a single spot to get the spot up to 95° degrees Fahrenheit (35° C).

How many watts does a Chameleon need? – 75 W is the baseline for heating the basking spot.

If you want to heat the whole cage or just keep the heat more consistent, a 100 W or even 150 W bulb will do.

How does a 100W bulb get? – Typically, the 100W produces enough heat to get a basking spot up to 95° degrees Fahrenheit (35° C).

The surface of the bulb gets up to 250° degrees Fahrenheit (121° C) which is why you need to keep the bulb itself far from the reptile.

Should I turn my Chameleon light off at night? – Yes. Turning the light off lowers the temperature and lessens the brightness of the cage.

This allows the Chameleon to follow a natural day-night cycle.
