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).

Versatile Room Divider With Easy Assembly and Strong Coverage
Size: 3 Panel 12FT W
I picked up this Siebwin 3-panel folding room divider mainly for privacy and room separation, and overall it works very well. Assembly is very straightforward, and the divider can be set up, taken apart, and stored without much effort. The fabric quality feels good, and the frame construction is stronger and more stable than expected. The support tubes especially feel well built and help keep the divider standing securely. One feature I really liked is the flexibility of the design. The panels can be used together as a complete divider or separated depending on the setup and available space. That makes it much more versatile for different room layouts or temporary privacy needs. The coverage is also very good, and the size matches the manufacturer’s description accurately. The fabric blocks light and background visibility well enough to provide solid privacy without feeling overly heavy. The wider feet also help improve stability compared to thinner folding dividers. Another positive detail is that everything arrived complete with no missing parts or damaged pieces, which made assembly much easier and faster. Compared to cheaper privacy screens, this one feels more durable and easier to customize depending on the situation. In terms of value for the money, it feels like a very practical and worthwhile purchase considering the size, flexibility, and build quality. Overall, a versatile and well-built room divider with easy assembly, strong privacy coverage, stable construction, complete included parts, flexible panel configuration, and excellent everyday functionality.

Stable, flexible in deployment configuration, creates true privacy and looks great.
Size: 3 Panel 12FT W
This is the second room divider panel I have installed, and there are several features about this one that I like much better than my older one. The fact that there are no gaps and that the material is thicker means you get more privacy or more hiding power, if you wish. My older divider has vertical spaces between each of the panels and the panels are half as wide as the Siebwin panels, so there are many vertical spaces. The Siebwin divider really creates privacy. Another feature that I really appreciate is that the legs are wider and stand off from the floor. On my older one the legs are flat and they're rather awkward to adjust because they create more drag on the floor. The feet on the older one also loosen if you turn them counter clockwise, so adjustments of configuration that require the feet to be moved are more complex. The older divider also must be deployed in a zig-zag fashion because he feet are not as wide, but this new one can be deployed and stable in a straight, an "N" shape or an arc. They are both the same length, but because the older one must be use in a zig-zag deployment it doesn't reach to the length of the new one. The Siebwin divider definitely costs more at $103.48, but it sports several features and advantages over the other brand, so it does a better job and is worth the extra cost.

Easy to assemble, does the job, material is shiny nylon and shows creases, minor defects, sloppy
Size: 3 Panel 12FT W, Size: 3 Panel 12FT W
The Siebwin room divider is a good idea, and for the price, it mostly delivers on the intended functionality. I ordered the 12 foot, 3-panel version mainly to hide an unfinished basement storage area that had become an eyesore. It works well for that purpose and gives the space a cleaner appearance without spending the kind of money that more decorative dividers or custom partitions cost. If you need something temporary, portable, or mainly functional, this is a viable option. There are a few limitations that became obvious during setup and use. The first thing I noticed was that the weld quality on some of the metal poles is fairly sloppy. Once the cover is installed, you do not really see it, but up close, it does not look especially refined or professional. The blackout material also is not a matte canvas style fabric as I expected. It has more of a shiny nylon appearance, and the creases are fairly visible. Being that it’s more of a nylon, I’d be hesitant to try steaming it to remove the creases. However, the creases do not matter if you are using it in a basement, dorm, or shared room, but for photography, video work, or a professional office setting, the appearance could be disappointing. The fabric is thick enough, though. It blocks visibility well enough, but strong light behind it still shows through to some extent, nothing deal-breaking. Also, my fabric appeared to be slightly defective. The hook and loop strip on one of the bottom sections was off-center and couldn't be totally attached because it was lined up with one of the legs. I originally hoped to use this as a video backdrop, but I will probably end up replacing the fabric with a proper green screen or canvas material while continuing to use the frame itself. For now, it does a good job of covering my basement junk. Assembly was actually easier than I expected and took roughly 15 to 20 minutes. The longer vertical poles are tethered together similarly to tent poles, which made setup straightforward and fairly intuitive. The shorter horizontal pieces slide and snap together to the top and bottom of the vertical assembly. After each section is assembled, the divider panels connect together with metal plates and two knurled screws (at the top and bottom), so no tools are really required. A few screws were difficult to start because paint had gotten into the threads, but once they caught, they tightened down normally. The feet install with similar knurled fasteners and help keep the divider reasonably stable. One thing to watch for during setup is the fabric orientation. There is one arrow indicator in the middle of the fabric to indicate up. However, if you need another indicator, the smaller hook and loop strip goes on the bottom while the longer strip goes on top. I realized mine was upside down right before finishing and had to redo it. I wasn't difficult to redo, despite the defect in mine. The overall design is practical and easy to move around. I do like that the panels can fold and bend into different shapes depending on the space. The widened feet help stability, although when trying to stretch the fabric tight, I noticed the poles sometimes wanted to overlap slightly at the joints. Tightening everything helped somewhat, but it still happened occasionally. The divider feels adequate for normal indoor use, though I would not expect premium durability or luxury-level fit and finish at this price point. The entire device can also be easily disabled and stored in a tote if you need it completely out of the way. It comes with assembly instructions, but even if you didn’t have them, it’s easy to build without them (save a mistake or two). In terms of value, I think the Siebwin divider mostly matches its price. Around $100 gets you a large freestanding partition with decent usability and easy assembly, but there are compromises in materials, appearance, and refinement. The defects are also off-putting, but hopefully you won't have them. Higher-end room dividers can easily cost two or three times more, so some of the tradeoffs are expected. I also noticed cheaper alternatives online, but based on the quality here, I suspect those would probably have even more issues. For practical home use, temporary privacy, hiding storage areas, or separating shared spaces, this is a good option as long as expectations stay realistic.

Works well but takes up more space than expected
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
This room divider does the job for creating a little extra privacy and was easy enough to set up. The panels feel decent quality and the wider feet help keep it more stable than some cheaper screens I’ve tried. My only issue is that it takes up a bit more room than I expected, especially with the feet sticking out. It’s still portable and folds away nicely, but definitely measure your space first. Overall it works well for separating a room or blocking off an area temporarily. i wish it came in other colors

Nice divider, serves it's purpose well!
Size: 3 Panel 12FT W
This room divider worked out very well for what I needed. I wanted a simple way to create a little more privacy and separation in a larger room without doing anything permanent, and this divider was an easy solution. The panels provide good coverage, and the black color gives it a clean, modern appearance that blends in nicely with different décor styles. Assembly was fairly straightforward, and once set up, the wider feet helped keep the divider stable on the floor. I was especially happy with how flexible the panels are to arrange. You can keep it mostly straight, angle it around furniture, or create a more enclosed private space depending on the layout you need. The material allows light to filter through slightly while still offering a noticeable sense of privacy. I’ve used it for separating a workspace area, but it would also work well in bedrooms, apartments, dorms, studios, or shared living spaces. Another plus is that it can be folded and moved without too much effort when you want to change the setup. Overall, this divider delivers a good balance of functionality, portability, and appearance. It’s a practical option for anyone needing temporary room separation without installing permanent walls or curtains.
