UV lights are not the same as the regular types so you should use it correctly. 

When you set up the hot zone for basking, you should make use of bulbs to cover the whole body of your reptiles better than heating only a small spot. 

Don’t put the UV light at the side of the enclosure because the reptiles have thick ridge for protecting eyes from the sun.

Thus, if you do that, then it will glare into your pet’s eyes directly and cause some damage. 

Remember to maintain the suitable distance between the lighting and your pet, at least 6 inches, and not over 18 inches.

You also have to replace it after 6-12 months as manufacturer’s instruction since the UV bulbs produce a diminishing about of ultraviolet B over time. 

Don’t forget to set the whole enclosure by light, you should provide some kind of place for your pet to be away from the UVB device sometimes and maintain a 12-hour cycle of day & night.
