REPTI ZOO Terrarium Light Day And Night

  • Touch-type light control switches can control light intensity and brightness at different levels.
  • The led reptile light provides ultra-long life about 20000 hours.
  • The led terrarium light has memory function when power off.

This lighting system is one of the best choices for LED lighting for a crested gecko tank. It emits 6500K natural white light.

Why you should get it for your crested gecko?

  1. Being LED, it does not emit heat.
  2. It has a dimmable switch. You can control the intensity and brightness of the light.
  3. It has 3 colors: white, white/blue mix, and all blue. The blue light is dim and can be used as a night light if needed – the dim blue light will not disrupt the normal circadian cycle of your crested gecko.


Since this light is meant for roof fitting, it won’t be effective in terrariums with very high ceilings.

Exo Terra PT2335

Exo Terra PT2335
  • Convenient and energy-efficient day & night lighting
  • Ideal for reptiles and amphibians with NO UVB-requirements
  • Allows natural nighttime temperature drops

This is another day/night LED light that will provide lighting without heating the enclosure.

Why you should get it for your crested gecko?

  1. The bright white light of the LED creates natural daylight. The blue light is dim and mimics moonlight. It does not disrupt the sleep cycle of your crested gecko.
  2. It is pretty energy efficient and won’t show up significantly on your electricity bill.


  1. It does not have a hook or fixture to attach to the enclosure. Instead, it uses adhesive. This makes it unreliable in terms of staying up on the wall. Especially after misting, sometimes, this light may fall off.
  2. It is not suitable for bigger and more spacious terrariums.

Do Crested Need Light In Captivity?

Crested geckos don’t necessarily need artificial light in captivity.

If you can place your crested gecko enclosure in a room where there is ample natural sunlight, you don’t need to include an artificial lighting system.

In fact, in that case, you should avoid using a lighting system.

The natural sunlight will maintain the circadian cycle of your crested gecko.

However, if your enclosure room does not have ample sunlight, you should consider getting a lighting system.

Not only is the light necessary to mimic the day/night cycle, but it is important to find a light source that mimics natural sunlight to ensure the absorption of calcium in your crested gecko.

The light source that you provide should provide UVB that is present in natural sunlight because UVB rays promote the absorption of calcium in the body.

Is Lighting Necessary In A Crested Gecko’s Habitat? (Benefits)

Lighting becomes necessary when the enclosure of the crested gecko does not have access to natural sunlight.

Crested geckos are nocturnal. So, if their enclosures don’t get enough light, it may disrupt their sleep cycle and make them tired and lethargic.

Moreover, natural sunlight promotes the absorption of calcium in the body.

With no lighting in the enclosure – natural or otherwise – your crested gecko will become prone to calcium deficiency.

The major benefits of lighting in case of the absence of natural sunlight are:

  • It promotes the natural sleep cycle. Your crested gecko will be well rested if it gets the daytime light needed for it to rest.
  • It promotes a healthy circadian cycle. Your crested gecko should get ample “night” time as well to get active.
  • It prevents metabolic bone disorder by promoting the absorption of calcium by the body.

Do Crested Geckos Need Light At Night?

No, crested geckos do not need light at night. Any lighting system should be dimmed or turned off during the night.

Crested geckos are nocturnal. So, when they see light, they feel it is daytime. They will choose to rest during that time.

It is at night, after dark, that they become very active.

So, at night, there should be no light in the enclosure.

If you can maintain it, you should try adding just enough light that mimics the moonlight during the night – it will add more of a natural atmosphere.

Types Of Crested Gecko Lighting

Usually, any simple fluorescent lighting works just fine.

But given the plethora of choices available in the market, it can get difficult or overwhelming to make a choice.

The importance, benefits, and harms of different kinds of lighting have been given below to help you make an informed choice.


An LED bulb is good for when you want your lighting system to just give light – not heat. It is common knowledge that bulbs and most light sources emit heat.

This can sometimes dysregulate the temperature condition of the enclosure and make your crested gecko uncomfortable.

An LED light will prevent such occurrence as it only emits light, it does not heat up.


UVA light mimics the natural lighting of a crested gecko’s habitat. It aids in behavior regulation and promotes natural behaviors in crested geckos.

This keeps the crested gecko physically, mentally, and behaviorally healthy.


UVB light has been a point of controversy among breeders and crested gecko owners.

Some believe that UVB is not needed while others believe that UVB is essential for health purposes as it promotes the absorption of calcium by aiding in the production of vitamin D3.

Here’s the thing – you can avoid UVB lighting if you provide vitamin D3-dusted insects to your crested gecko.

So, you don’t need it for the health of your crested gecko. But you also can get one if you want to. It won’t harm your crested gecko either.

As far as the UVB lighting is concerned, the ball is in your court. Just remember to not expose your crested gecko to UVB for more than 4 to 6 hours.


You should not expose your crested gecko to UVC lighting for prolonged times. It can get fatal.

So, you clearly should not be using it as a lighting system for your crested gecko tank.

UVC, however, does help in killing bacteria.

So, you can use it while deep cleaning the tank of your crested gecko.

Which Is Better – LED, UVA, UVB, And UVC?

UVA is very important for crested geckos.

But the catch is that almost all lights – LED, UVB, tanning bulbs, basking bulbs, incandescent, and fluorescent bulbs emit UVA in certain amounts.

So, you may or may not require specific UVA lighting inside the enclosure.

LED is a better choice than UVB and UVC if you already have a heating system.

UVB is completely based on your preference. UVC should be avoided completely.

Tips And Tricks Using Crested Gecko Lighting

  1. Don’t ever let your crested gecko enclosure be directly exposed to sunlight. Remember that crested geckos come from rainforests. With all that tree cover that exists in a rainforest, there is seldom a spot with too much direct sunlight.
  2. Avoid lights that emit a lot of heat. Crested geckos feel at ease at room temperature (72 to 75 degrees Fahrenheit).
  3. LED bulbs may be more expensive but they are environment-friendly, and they stimulate plant growth inside the enclosure.
  4. LED bulbs don’t emit heat. They’ll keep your crested gecko comfortable in terms of temperature.
  5. Don’t leave the lights on at night. It will disrupt the circadian and sleep cycle of your crested gecko.
  6. If possible, go for lights with dimmable switches. Gradually dim the brightness of the light throughout the day to promote an even more natural environment.

How To Set-Up Lighting In A Crested Gecko’s Terrarium

To set up the lighting in your crested gecko’s terrarium, you need to get two things: the required lightbulb and a light fixture.

Additionally, you could also get a lampstand.

Most light fixtures come with a hook on top or a clamp to their side.

You simply need to add the lightbulb to the fixture and then clamp the fixture to the wall of your crested gecko’s enclosure.

Two things to keep in mind when adding the lighting system to your crested gecko tank are:

  1. The light should directly enter the enclosure. Any kind of plastic or glass acts as a screen that filters out the essential UVA and UVB rays.
  2. The light should be positioned in a manner that your crested gecko gets direct light but cannot easily access the lightbulb. This is very important especially if you use a light source that emits heat. Preferably, hang or clamp the light to a corner on the roof of the enclosure.


Crested geckos are nocturnal. So, they usually don’t need a lighting system if they have ample natural lighting.

However, if you do choose to get a light for your crested gecko, go for one that provides UVA and UVB rays.

Exposure to these rays for short periods every day promotes healthy behavior and the functioning of crested geckos.

LEDs are an excellent choice for long-duration day/night lighting because they don’t emit any heat.
