Kate kirjutas: terraariumit, kus UV-lamp on juba kaane sees
Kate kirjutas: Aga nagu ma siit aru saan on osa UV-lampe kaladele, osa roomajatele mõeldud. Mis vahe neil siis on?.
Kate kirjutas: Ja soojenduslambi asemel soovitati mulle soojendusplaati hoopis.
Even the largest glass tank is entirely inadequate - and in our opinion, is inhumane.
Helen kirjutas:esiteks peaks minu meelest kalade lambid ja roomajate lambid erinevad olema. kaladel korraga vist 2 erinevat toru (üks taimedele?) - maeitea sellest mitte mõhkugi!

In the tropics the light intensity of the sun at ground level is in the region of 1,000,000 Lux. By comparison, a 40W incandescent lamp typically produces less than 50 Lux when measured at a distance of only 1 meter!
...described as "full spectrum". In fact they are ordinary incandescent lamps with a built-in blue filter. They emit no useful UV.
black light are used for special effects in discotheques. This type of lamp is of no use to reptiles. Other types are used for various industrial purposes, for example, in sterilizers. This type of lamp can be positively dangerous to living creatures, including humans, as they emit UV-C which can cause skin cancer and eye-damage
Today, there are a wide range of high quality fluorescent tubes available which are specifically designed for use with reptiles. Note that fluorescent tubes do not provide any heat output and that a separate, incandescent, basking lamp is always required in addition.
Color temperature - nothing to do with heat. ... At the tropics, or in a desert, the color temperature can reach 6,500 K.
many reptiles are believed to be able to see into the UVA range (320-400 nm), and this is likely to have a profound effect upon behaviour, and specifically, how they visualise food items.
Color Rendering Index: Color rendering is the degree to which a light source shows the true colors of the objects it illuminates. This is measured on a color rendering index, rated from 0-100. A normal fluorescent lamp, for example, rates 54 on the CRI scale. High quality fluorescent lamps designed for reptile use will rate 80-90 on the same scale. Color rendering is very important as many reptiles rely upon color signals for reproductive and feeding purposes.
UVB is greatly attenuated by glass, plastic and even fine mesh (the tube envelope itself is a special type of glass which does permit UV transmission). The amount of UVB received also diminishes extremely quickly with distance. It is generally recommended that such tubes be no further than 18" (46 cm) away from the subject. For reptiles with very high UVB requirement, such as desert species, tubes should be placed as close as 10-12" (25-30 cm)
Tubes also have a very limited life. Most will require changing every at least 12 months in order to guarantee continued UVB output. There is evidence that some tubes fail to produce advertised levels of UV-B after only 6 months of use. Although there may be no visible deterioration in the performance of the tube, there is ample evidence that the invisible UV content decays rapidly as the tube ages.
Tubes are available offering from 2% UVB to 8% UVB. In the vast majority of cases the 3% tubes are perfectly adequate, provided they are correctly sited, changed regularly, and a sufficient number of hours exposure permitted. For a 3-5% tube, 10-12 hours daily has proved a satisfactory level of exposure for most species. Concerns have been expressed about the safety of tubes with outputs greater than 5% - in particular, there may be a possibility of eye damage occurring with some tubes in some situations.
UV-B Heat Lamps (Self-Ballasted Mercury Vapor) - ... revolutionary product ... they also emit very significant levels of essential UV-B. Not only that, but they also emit a very useful amount of heat. The levels of UV-B and UV-A produced by these lamps is extremely impressive. At 30 cm, it approximates that at midday in the Mediterranean. The lifespan of these lamps is also excellent.
They appear expensive at first sight (from $40-$60 upwards each), but given their excellent performance and longevity, are actually cheaper in the long run than UV-B fluorescent tubes.
Conclusion: Despite advances in lamp design, there is still no substitute for natural sunlight. Wherever possible....
The view of the Tortoise Trust that tubes alone should not be relied upon exclusively to provide vitamin D3. It is our opinion that it is far safer to continue to provide a high quality combined calcium-D3 supplement orally, even where full spectrum tubes are employed.
