Vivarium Lighting: UVB
UVB bulbs for bioactive terrariums & live vivariums
About Our Lighting Supplies:
Certain animals require UVB light to naturally process vitamin D3, but the actual environments we build (i.e. plants) do not require UVB light to thrive. Plants require PAR light (photosynthetically active radiation), which is measured between 400-720nm, while UVB light is measured between 290-320nm. If the inhabitant species you care for will benefit from UVB lighting, you should offer a UVB basking spot. If the animal(s) you are working with don't require or benefit from light in the UVB spectrum, your environment won't require it either. The UVB light you choose will depend on your animal species.

Why we recommend Zoo Med UVB Bulbs

Zoo Med sets the standard for Reptile UVB lighting, and their user reviews are sky-high by comparison to other mainstream brands. Our recommendation goes a step further than that, though. While no manufacturer seems to print color temperature on their product packaging, Zoo Med's bulbs appear closer to the recommended 5000-6500K color temperature range than other brands. (Seen in the photo above) An appropriate color temperature like this one plays a big part in how naturally accurate a live vivarium will appear to the human eye. It's just an aesthetic observation, but that's important when we're working with a beautiful living environment. While many brands of UVB light will work, Zoo Med's bulbs will work and produce naturally accurate light for a live vivarium.

Zoo Med Reptisun LED UVB Bar
All the perks of a Reptisun LED plus a T5HO UVB Tube!
NEHERP Staff Description:
These fixtures combine everything we love about the 2'nd generation Reptisun LED models with the added reliability & predictability of Zoo Med's Reptisun T5HO UVB. The LED side grows plants beautifully, while the fluorescent Reptisun T5HO Bulb offers beneficial UVB output for inhabitants which will benefit from it. The built-in ramp timer allows for a gradual sunrise and sunset each morning & evening with the LED diodes. The T5HO tube is controlled by a separate digital timer, which we typically set to run once the full "day" mode has been reached. This is NEHERP's best plant growth and UVB output combo solution.
Manufacturer Description:
Boasts powerful built-in LEDs for ultimate pet viewing while also powering up the included Reptisun® 5.0 T5 HO UVB bulb for safe and effective UVB. The ReptiSun LED UVB offers the best lighting for your animal. Program up to a 90-minute sunrise/sunset with the LEDs, and set peak brightness for LEDs from 10-100%. The T5 light operates on a separate timer for the most natural lighting experience possible. Two separate timers controlled by a handheld remote: A digital timer turns the UVB bulb on and off at your desired time. Separate timer for the LEDs allows for a gradual sunrise and sunset effect by ramping up or down the intensity of the LEDs.
