Which
UVB light should I use?
The best
UVB light is a ReptiSun 10.0 fluorescent tube HO (Or Arcardia 12% in the UK). Compact or coil bulbs do not emit the proper amount of
UVB light for a bearded dragon, and should not be used. Other brands, such as the Zilla Desert Series and ReptiGlo have been known to cause eye problems and other health issues with bearded dragons, and should be avoided. The reason that some UVB lights (Zilla, ReptiGlo, coils/compacts, ect.) are considered dangerous is because the wavelength of UVB that they emit is shorter and more intense than the wavelength of the "safe" lights (ReptiSun, Arcadia). UVB lights should be replaced every 6 months. The T5’s are a strong bulb and only need to be replaced once a year – the T 8 every 6 months--- where as the T 8 are not as strong—they need to be placed inside the tank the T 5 10.0 bulb approx 10-11 inches from basking spot – the T 8 approx 8-10 inches from basking spot—the cover needs to be off the bulb for full effect of the UVB rays--
The Reptiglo brand is also not recommended, tube, coil or compact, as it has been associated with causing eye problems, lethargy and not eating.
These fluorescent bulbs should stretch the length of your Beardies enclosure and your B.D. should be able to come within 6-8 inches of the light. The UVB should be mounted inside the tank to allow your dragon 100% of the UVB. On top of the tank can filter out up to 50% of the UVB rays your dragon needs. Mercury vapour bulbs are also a good heat & UVB source, but to allow your dragon full use of the UVB it is best to not use the mesh tank tops. Mounting them on a lampstand with a dome without using a top will allow full use of the UVB. Having the correct type of
UVB light is also important to help their bones develop strong and healthy. The bold I do not recommend full length -- the need to be able to escape the rays and w/ it running full length they cant do that ----- 2/3 of the tank is good -------------
I hope this helps in answering your question --- Amazon is where you were talking about pricing I am assuming ??
