Any plastic cage can have a light installed in it if you want one. A radiant heat panel will keep your cage at the right temperature in a room that dips under 70 degrees though many will tell you that a UTH is superior because snakes aren't accustomed to heat from above in a natural setting. But to me it is a good choice if you live where the winter is cold and keeping room or ambient home temperature up high is too costly.
