What is Light?Sunlight arrives at the top of the earth's atmosphere at a power level of about one kilowatt per square meter. It is by this energy that all life-processes on earth are ultimatelydriven. Without the sun's constant energy input our planet would quickly radiate away itsown energy in short order, making all life extinct. Light is referred to as electromagneticradiation because the true nature of light is based on tiny electro-magnetic fields, calledphotons. These photons of light can have many different energy levels or wavelengths,which are expressed in nanometers (nm). The most familiar wavelengths are the visible ones. Every wavelength is represented by a different colour. For example, the Sunappears as yellow because its light is most powerful at the visible wavelength of yellow.However, there are many other wavelengths beyond visible light. All of them together arecalled the electromagnetic spectrum. At the most powerful end of the spectrum are thegamma rays, followed by X-rays, then ultraviolet light, and then visible light which takesup only a tiny fraction of the electromagnetic spectrum and is sandwiched between ultraviolet and infrared light. Infrared light is familiar to us as heat. The spectrum continuesas microwaves and ends in radio waves, the least powerful photons. Of the entire electromagnetic spectrum, only ultraviolet light, visible light and infrared light are important tous at this sible Light400500600700120,000Radiowaves100 billionWavelength (nm)Electromagnetic spectrumVisible LightBesides providing us (and reptiles) with light to see properly, the indication of daytimeand night time (light and dark) is an important function. The visible light spectrum ranges from 390 to 700 nm. The light registered by the eye, and the colour of it, dependson the strength of each wavelength. The Colouring Rendering Index (CRI) expresses theability of a light source to illuminate an object as compared to natural light, with naturalsunlight having a CRI of 100. Nowadays, every artificial light source with a CRI above 95is considered to be a full-spectrum light, since it is able to light-up an object as it wouldappear under natural light and thus receive a certain amount of any wavelength within thevisible spectrum. Closely related is the colour temperature, expressed in Kelvin (K), todefine the colour of the light emitted.Reptile Lighting4What is Light?In describing colour temperatures, a low colour temperature corresponds to a warm or ared-yellow appearance like incandescent lamps, around 2500 Kelvin. Fluorescent lamps,operating at 4500 Kelvin or higher, emit a white-bluish light. In colour temperature, thehigher the Kelvin temperature, the whiter and bluer the light.The standard average temperature for daylight is about 5600K, although it can rangefrom as low as 2000K at sunset, to more than 18000K in overcast or humid conditions.To obtain natural visible light conditions in the terrarium, it is important to choose a lightsource with the highest possible CRI and a colour temperature from around 6000K foroptimal colours in animals and plants. Terrarium plants benefit from certain wavelengthswithin the visible light for photosynthesis. This is a process by which plants use theenergy from light to produce sugar, the "fuel" used by all living things. The conversion oflight into usable energy is associated with the green pigment Chlorophyll. A light sourcewith a high output in the 400-450 nm range promotes plant growth and health.Ultraviolet LightUltraviolet or UV light is a high energy portion of the electromagnetic spectrum, justbeyond visible light.The UV-spectrum is divided into three wavelength groups: UVA - Long wave ultraviolet A, ranges from 320-400 nm and is of significantimportance for reptiles. UVB - Medium wave ultraviolet B, ranges from 290-320 nm and is the mostimportant for reptile purposes UVC - Short wave ultraviolet C, ranges from 180-290 nm and is dangerousto all living organismsIt has been demonstrated that UVA can influence agonistic, reproductive, and signallingbehaviours in reptiles. As reptiles can see into the UVA range (320-400 nm) it will affectthe way they see things. The colour of their food or their bodies will appear different in areptile’s eye then the way we see it if exposed to UVA radiation. Signalling by exposingbody parts (e.g. Anolis sp.) or changing colours (e.g. Chameleon sp.) is common inreptiles, these signals are perceived and also interpreted differently by reptiles if UVAradiation is absent. Failure to provide UVA to diurnal reptiles can cause stress by alteringthe reptile's perception of its surroundings and how it responds to it. This is crucial forbreeding or keeping them around for the length of their natural life span.

UVB is generally defined as the wavelength band from 290-320 nm. In the wild, mostreptiles synthesize their vitamin D3 from the UVB component of sunlight. Vitamin D3is essential for the effective metabolism of dietary calcium in reptiles. UVB reacts withthe precursor of vitamin D, 7-dehydrocholesterol, in the skin to produce provitamin D3.Depending on heat and the aid of a mechanism in the skin, provitamin D3 is convertedinto vitamin D3 itself. The liver and kidneys transform vitamin D3 into its active form, ahormone (1,25, hydroxy-vitamin D) that regulates calcium metabolism.Carnivorous and omnivorous reptiles get a high proportion of their vitamin D3requirement from their food. However, plants do not contain D3 (cholecalciferol), insteadthey contain D2 (ergocalciferol), which is far less efficient in calcium metabolism thanD3. Herbivorous reptiles are therefore far more dependent upon the quantity and qualityof artificial lighting than carnivorous specimens.The earth’s climate is determined by the amount of solar radiation that strikes thesurface. Factors like the sun’s position, the earth’s rotation, geographic location, theozone layer, clouds, air-humidity, elevation, environment, etc. influence the intensity oflight. Also within the microhabitat the light intensity of both visual and non-visual lightvaries, depending on the density of the vegetation or geological conditions. The amountof light falling on a surface is known as the illuminance and is measured in lumens persquare meter or lux. The illuminance of direct sunlight is approximately 100,000 lux, butnormal daylight, which is filtered through a cloudy sky, is between 5,000 and 10,000 lux,while moonlight can be as little as 0.25 lux.If inadequate vitamin D3 is available, the animal will rapidly develop the conditionknown as Metabolic Bone Disease. In this condition, bone density suffers and variousother serious metabolic problems occur. Symptoms include swelling, lethargy, generalweakness, tremors and softening of the shell in turtles and tortoises. Next to a UVB lightsource, adequate levels of calcium must be present in the diet or must be provided bymeans of dietary supplementation. Juvenile reptiles are most at risk, although adultstoo can be affected if maintained in a state of deficiency for a long enough period. Egglaying females are also at great risk, due to the extra demands in calcium necessary foregg production.Ultraviolet radiation is expressed in microwatt per square centimetre (mW/cm2) andvaries tremendously from the poles (low) towards the equator (high). The amount ofUVB radiation received on the equator on a clear day at noon lies around 270 mW/cm2.However, this high amount of radiation decreases as the day passes, in the same way thatit had increased since sunrise, and taking into account that not all days are clear. In thewild, basking activities of most reptiles are limited to early morning and late afternoon.The rest of the day is spent in the shade, either in burrows, crevices or other shadedplaces or at various places in leafy bushes, shrubs or trees. In tropical forests, hometo many types of reptiles and amphibians, only a little direct sun penetrates the forestcanopy and underlying layers to reach the ground.Infrared LightThe UV radiation and light levels to which the reptiles are exposured can vary,depending on a variety of factors:The ectothermic nature of reptiles (being cold-blooded) emphasizes the importanceof infrared radiation (heat) for thermoregulation. The infrared segment of theelectromagnetic spectrum occurs just below or “infra” to red light and is not visible. Itcan, however, be perceived as heat by the skin. The sun produces most of its energyoutput in the infrared segment of the spectrum. The best artificial source of heat fordiurnal reptiles is through an overhead radiant source by means of incandescent lightbulbs, all emitting high amounts of infrared light ( 700 nm).Reptile Lighting6The IntensityWhat is Light?Habitat:Forest and shrub areas provide more shade than plains and deserts. Dense forestshave many gradients of UV radiation, with high levels in the forest canopy to very lowUV-levels on the forest floor. Grasslands and savannahs provide the same gradientsfor smaller species, whereas larger species are more exposed. In deserts there is lessprotection from direct sunlight, and UV levels can even be amplified by reflection. Somemountainous regions have valleys, meaning that sunlight may only penetrate the habitatseveral hours after sunrise, considerably reducing the length of exposure to UV rays.

Activity Patterns:Diurnal (active during daytime) animals receive higher levels of UV than nocturnalspecies for obvious reasons. But even diurnal reptiles do not spend all day in directsunlight. Many species seek cover during the hottest time of the day to avoid overheating. Their basking periods are limited to morning hours and late afternoon. Theseactivity cycles may change in reptiles from seasonal regions. Some nocturnal animalsare exposed to UV radiation as their resting location receives sunlight and some evencome out of their hiding spots toVariation in solar power at the Tropic of Cancerbask in the sun for thermoregulationpurposes.Time of Day:The sun is at its highest in the skyaround noon. At this time, the sun’srays have the least distance to travelthrough the atmosphere and UVB levelsare at their highest. In the earlymorning and late afternoon, the sun’srays pass through the atmosphere atan angle and their intensity is greatlyreduced.Time of Year:The sun’s angle varies with the seasons, causingthe intensity of UV rays to change. UV intensitytends to be highest during the summer months.In the Northern Hemisphere, the sun shinesdirectly overhead at noon at the Tropic of Canceron the first day of summer, at the equator onthe first day of spring and autumn, and directlyoverhead at the Tropic of Capricorn on the firstday of the winter.Latitude:The sun’s rays are strongest at the equator,where the sun is most directly overhead and UVrays must travel the least distance through theatmosphere. Also the ozone is naturally thinnerin the tropics compared to mid- and highlatitudes, so there is less ozone to absorb theNTropic of CancerTropic of CapricornSNTropic of CancerEquatorSNJune 21Tropic of CancerEquatorReptile LightingThe IntensityDec. 21Tropic of CapricornTropic of CapricornS8Mar. 21 / Sept. 21EquatorNAtmosphereRadiationPathlengths troughatmosphere increaseat higher latitudesEquatorSUVB - HotspotsUV radiation as it passes through the atmosphere. At higher latitudes the sun is lowerin the sky, so UV rays must travel a greater distance through ozone-rich portions of theatmosphere and, in turn, expose those latitudes to less UV radiation.Altitude:UV intensity increases with altitudebecause there is less atmosphere toabsorb the sun rays.Weather Conditions:Clouds play a big role in the amountof UV radiation reaching the ground.On a cloudy day, depending on theshape and thickness of the clouds,they can absorb and reflect35-85% of the sun’s radiant energy,and along with the other effects preventall but a negligible amount of radiationSunrays, Reunion Islandfrom reaching the ground. Manyreptiles seek the security of their burrows or hidingplaces during rain, stormy and overcast conditions.Reflection:Some surfaces, such as sand (12%), grass (10%) or water (5%) can reflect muchof the UV radiation that reaches them. Because of this reflection, UV intensity can bedeceptively high even in shaded areas.Ozone:The ozone layer absorbs some of the UV radiation that would otherwise reach theearth’s surface. Ozone levels vary over the year (even throughout the day) and from onegeographical location to another.

Exo Terra ReptileLightingWithout the sun’s energy, all life on earth would cease to exist. It is by the sun’s energy thatall life forces are driven. Without it, our planet would quickly radiate away its own energyin short order, making all life extinct. Although light is much more complex, there are onlythree facets of light that are important for reptile husbandry: ultraviolet light, visible lightand infrared light. In order to create these three biological aspects of sunlight artificially,Exo Terra has developed several specialized lights. Reptiles require appropriate and highquality lighting in order to meet certain different metabolic needs. As it is almost impossibleto accommodate all of these needs in a single light source, a combination of different lightsources is necessary in most cases. The table at right will help you in making the rightlighting choice. Not all reptiles or terrarium animals need the same amount of UVB radiation:nocturnal versus daylight activity, geographical and climatological conditions (ex: rainforestsversus deserts).

ReptileUVB100The most important feature of a fluorescent bulb is the ability to emit sufficientUVB light (ultraviolet B), a component of sunlight, whereas an incandescent lamponly emits very limited amounts of UVA light. It is impossible to accommodate ahigh visible light emission with a high ultraviolet (UV) output. The more visible lightemitted, the less UV radiation and vice versa. Fluorescent bulbs do not provide sufficient heat. In addition, a separate heat sourcelike a heat or basking bulb is required. It is recommended to combine a Reptile UVBbulb with a the proper visual light output for optimal results.Tropical Terrarium BulbIdeal for all tropical and sub-tropical reptilesOptimal levels of UVBEffective up to 40 cm (15”)Provides necessary UVB rays for optimal calciummetabolism UVA rays stimulate appetite, activity andreproductive behavior Combine with Natural Light or Reptile Vision foroptimal visual light outputThe Exo Terra Reptile UVB100 emits optimal levels ofUVB, similar to that of shady environments such asrain forests or other tropical locations. Reptiles livingin these habitats receive moderate UV radiation due toclimatological conditions (fairly high humidity, changesin weather, etc) that prevent unfiltered sunlight fromreaching the reptile’s basking site. The optimalVitamin D3 yield index ensures vitamin D3photosynthesis to aid calcium absorption andprevent metabolic diseases.13WDistanceUVAPhotoUVB -synth. UVB Rating Illumin.InchµW/cm²µW/cm²cmVit.
