Hi. I know they say that red or blue lights do not bother snakes at night as they can't see this frequency. But for those who have used red or blue night heat bulbs with their ball pythons, from experience, does it seem to bother them at all? Or are these just more marketing claims with no basis? If it does work ok with balls, does it work for colubrids? Do they see the red or blue at all and does it interupt their behavior?
