You don't need UV light at all for milk snakes. Whoever told you that was wrong. They need constant heat, an under tank heater is the best choice. Whatever you choose to use make sure you are keeping the correct temperature gradient.



Here is a care sheet, you can look up others as well if you need conformation about the UV light: http://www.drsfostersmith.com/pic/articl鈥?/a>How long do i leave the U VB light on?
FOREVER
The UVB/UVA light is the imitation of the rays of the sun. It helps reptiles produce vitiman D.



Leave it on as if it were the sun. Turn it on in the morning and turn it off at night.
