UVB flow tubes require an external starter (also referred to as a controller, motor or ballast), this is the electrical fitting that the bulb plugs into. Standard (T8) UVB flow tubes require the Core range of starters to work while the T5 high output UVB tubes require the specialist T5 starters.
UVB bulb reflectors will ensure that you get the maximum benefit from your UVB bulb by reflecting the UVB down into the enclosure and towards your reptile.
WHY ONLY ARCADIA UVB PRODUCTS?
There are many manufacturers of UVB products but the preferred brand of professional zoologist Will Thomas (MRes Natural Sciences, BSc Zoology with Marine Zoology) is Arcadia. After 11 years using this brand he has had no complaints or issues and therefore believes strongly in the use of their products. Will Thomas (MRes, BSc) is not in any way associated, affiliated or paid to endorse Arcadia lighting products and alternative UVB products are available from many other manufacturers.
