HOW DOES THE UV INDEX APPLY TO REPTILES?

The UV Index was developed as a tool for evaluating human risk of UV exposure outdoors. So how do we use it to evaluate UV lamps designed for use with reptiles in terrariums? This question was approached scientifically by a team of researchers led by the prominent herpetologist; Gary Ferguson, Ph.D. In their study, they took UV Index readings throughout the day in locations where they observed different species basking outdoors in sunlight or living in the shade. Using these UV Index readings, they were able to make recommendations for appropriate UV levels by creating four different UV Index “zones.” These zones were named the “Ferguson Zones” by Frances Baines (one of the authors and noted reptile photobiologist).

 

WHICH ZONE IS RIGHT FOR MY SPECIES?

Zone 1: UVI 0.4 to 0.7 (Shade/Crepuscular) Species in this zone can be either diurnal (active during the day) or crepuscular (active at dawn or dusk). They avoid direct sunlight exposure and are able to meet their vitamin D requirements through exposure to low levels of UVB typically found in the shade, or at dawn or dusk.

Zone 2: UVI 0.7 to 1.0 (Mostly partial sun/Occasional full sun baskers) This is a small range that is very close to Zone 1, but species in this zone will occasionally venture out into full sunlight for short periods of time. Examples include Green Anoles (Anolis carolinensis), Water Dragons (Physignathus cocincinus), Day Geckos (Phelsuma species), Skinks, Box Turtles (Terrapene species), Garter and Ribbon Snakes (Thamnophis species) and most species of diurnal Colubrid snakes (like Kings Snakes and Gopher Snakes). This zone is also recommended for Old World Chameleons (Panther Chameleons, Jackson’s Chameleons, and other Chameleo species). If you’re unsure what the appropriate zone is for a given species, Zone 2 can be used as a safe and effective level that will prevent the onset of metabolic bone disease or nutritional secondary hyperparathyroidism (NSHP).

Zone 3: UVI 1.0 to 2.6 (Mostly full sun/Occasional partial sun baskers) Zone 3 covers a fairly broad range and includes many species common to herpetoculture. These temperate, tropical, and sub-tropical species will bask in full sun early in the day or early afternoon. During mid day, they may be found basking when conditions are partly cloudy. This zone is appropriate for most species of aquatic turtles and tortoises. Many of the small spiny lizards of the genus Sceloporus fall into this zone, Monitors and Tegus, as well as Green Iguanas (Iguana iguana) and Curly-tailed Lizards of the genus Leiocephalus. With zone 3 and above, it is VERY IMPORTANT to provide a UVB gradient down to zone 1 UVB levels so that reptiles can “photoregulate” and adjust their UVB exposure as needed. Failure to provide a UVB gradient can result in illness, eye & skin damage, or even death.

Zone 4: UVI 2.6 to 3.5 or more (Mid day full sun baskers) Zone 4 species would include the majority of “desert” species that bask in full sunlight, even after Zone 3 species have retreated into burrows or the shade. Examples include Bearded Dragons (Pogona vitticeps), Uromastyx lizards, and Desert Iguanas (Dipsosaurus dorsalis). IMPORTANT: Just as with zone 3, it is critical that the habitat is large enough to provide a UVB gradient down to zone 1 levels to allow reptiles to photoregulate and adjust their UVB exposure. Failure to provide a UVB gradient can result in illness, eye & skin damage, or even death. Avoid UVI levels of 8.0 or more for zone 4 species as even the most sun-loving species retreat from full sunlight at these high levels (see lamp safety notes below for more info).

Hiding from Coworkers Has Never Looked So Classy
Color: Frost
Let me tell you something: this divider isn’t just a piece of furniture...it’s a sanctuary, a confessional booth for the emotionally exhausted, and a glorious wall between me and other people’s nonsense. I slid behind this beauty like a barfly dodging an ex, and baby, I felt safe. It's lightweight, but sturdy enough to block out both sunlight and bad vibes. The fabric’s got a fancy little texture, which is great if you're hiding and still wanna feel aesthetic. It moves easy, it stands tall, and it gives me just enough space to eat my sad desk lunch in peace while pretending I’m in a better timeline. Final Word: Perfect for offices, bedrooms, dressing rooms, or wherever you need to spiritually disassociate. Whether you’re blocking out sunlight or Barbara’s unsolicited MLM pitch, this thing’s got your back. Literally. Five stars. Would (and likely will) emotionally withdraw again.

Great quality, perfect height to block the sun from the skylights.
Color: Frost, Color: Frost
We have skylights in our home that don't have shades yet so when we are in our loft, the sun will either blind us or make it unable to see our monitors clearly. So while we're waiting on installing shades, we thought to get a cover to block out the sun and this is perfect! It's tall enough to block out the sun and easy enough to move around as the sun moves. I don't love the way the cover looks, but it seems like it might be changeable. I think for privacy when we have guests in the loft, we would need a few more of these. The base is very sturdy and the quality overall is perfect. It is pricey, but most of these panels are. So really happy with this divider!

Works great but lacking value
Color: Nocturne
It's a well packaged item including a simple tool set and a clear instruction. No smell. I put it together just by myself in about 15-20 minutes without any problems. The base is solid pieces of metal, and it stands very sturdy. It's also light enough for me to move it around in my office to serve different purposes. I like the color and the quality of the fabric. It blends in with my office space perfectly. I needed it as a partition between my desk and the door, and the background for my video conference call. Surprisingly, it can also deflect the air coming down from the AC vent behind my desk. I didn't expect it to 100% soundproofing (not its purpose), but I feel it did absorb some humming sound from my mini fridge behind my desk. Sturdy metal for free-standing, yet pretty light weight for easy assemble and to move around. Keeping it beside my desk to separate lounging and work area, and I could move it easily if I want a conference-call backdrop. I can tell some difference in the sound absorption, as my all-in-one space (kitchen, dining, work, living) area can sound loud at times, it does provide some damping effect. But I must say for the price I was expecting more. More solidity and weight. More privacy. It's just not very big for the price paid. A good price for two panels but this was just a single.

High quality divider, but at a high cost
Color: Nocturne
So if you've ever been into an office setting you've likely encountered some variety of this divider. There's a bunch of good things about this product. -It's a nice size -There are great color options, went with Nocturne and no regrets with that -It's sturdy with a good base -Offers a bit of sound deadening The biggest drawback of this product is the cost. It's pricey for ONE divider. I'm sure it would make a great set, although for me it would fiscally irresponsible.
