Making the right choice when it comes to UVB lighting is crucial for ensuring your reptile companions thrive.
UVB exposure enables reptiles to synthesize vitamin D3 and absorb calcium, supporting strong bones and overall health.
Conducting thorough research and comparing products is essential to find the perfect match for your chameleon’s specific needs.
Here’s the showdown of ReptiSun® 5.0 T5 HO vs PowerSun® UV 5.0 UVB Lamp vs ProT5® 5.0 UVB Kit…
Why Comparison Matters When Purchasing Reptile UVB Lighting
With the wide variety of UVB lighting options on the market, simply choosing the first product you see can be detrimental to your reptile’s wellbeing.
Consider the following reasons why taking the time to research and compare is a wise investment:
- UVB output varies greatly between products. Reptiles have specific UVB requirements depending on species, so output must align.
- Lifespan and required maintenance schedules differ. Frequent replacements can become costly over time.
- Enclosure size must be factored in. Bulb lengths and output levels impact coverage.
- Reputable manufacturers understand reptile physiology. This ensures safety and effectiveness.
- Your geographic location plays a role. Natural sunlight levels determine needs.
By evaluating all facets through comparison, you equip yourself to make the optimal selection for your reptile’s health and happiness.
Never underestimate the value of a well-informed purchase.

What level of UVB does a chameleon need?
When working with UVB bulbs the UVB strength is measured as what percentage of light produced is UVB. The most common for chameleon keepers is the 6% and 12%. Though there is 14% for special situations.
Is 5 or 10 UVB better for chameleons?
UVB Lighting is essential for chameleons to process calcium in captivity. Zoo Med’s ReptiSun® 5.0 or 10.0 Linear or Compact Fluorescent Lamps are a great choice for providing chameleons with UVB.
Can a Chameleon get too much UVB?
For species that spend their time in the shade, low UVB levels are appropriate. Chameleons see and seek out UVB light, but it is unclear whether the behavior is self-limiting or not; It happens that some chameleons may expose themselves to too much UVB and thus develop health problems.
How long can Chameleons go without UVB?
If a Chameleon is healthy and fully stocked on D3 / natural sunlight +reasonable calcium levels beforehand a sub adult to adult can last about two weeks before the earliest symptoms start to really show. Neurological functions are the first things to be affected.
How often should I change my UVB?
The UVB lamp should be replaced after a total exposure time of approx. 3500 hours. This does not mean immediate disposal – you can still use a used lamp with a lower UV intensity for young animals or a less sun-loving reptile species.
