diff. between UV & UVB

Ok I know I have seen this question before but I cant find the thread. What is the diff. between UV & UVB

[IguanaKing]

There really isn't a difference, UVB is just a specific portion of the UV wavelengths. UVA is 315-400 nanometers, UVB is 280-315, and UVC is 200-280.

To add to that:

UVA is the visible light which is thrown from bulbs and the sun which we can actually see. UVA plays an important role in the animals behavior. UVA light tells the animal when it is day, induces appetites, breeding
behavior and other activities such as climbing, running, jumping and hunting.

UVB is not visible. It is a form of radiation put out by the sun and special coated bulbs made to produce UVB wavelengths. UVB in reptiles allows the animal to process calcium in their system which helps to prevent and reverse metabolic bone disease. UVB in excess amounts can be harmful to both humans and animals causing problems such as damage to the retina of the eyes, burns and other health risks. UVB is what causes humans to suntan and sunburn. It is important to control the UVB lighting, or if using natural sunlight, to give the animal shade and areas where they can escape the constant exposure of UVB.

UVC is the wavelength used for Ultraviolet Sterilizers which kill harmful bacteria. This is a very dangerous wavelength to all animals as it can damage DNA.

Ok I guess that makes sense. Thanx for the input. ;D What typ of bulb gives off heat but not light? Just wondering so I can get the right bulb for night time.

Either a CHE or the new Mega-Ray HE. One member on here wasn't impressed with them, but I really like mine. It isn't meant to swath the area in heat...it actually projects it to a more localized spot...and will not burn an ig like a CHE does.

Alright one Mega-ray HE added to my X-mas list. ;D Thanx again.
