"Lights for Nighttime Use...
For night time use, one cannot use a white or any bright light.
Doing so causes disruption of the animal's sleep cycles, even if it appears to be sleeping
(sleep is comprised of different types of cycles which alternate during the course of the sleep session - bright light disrupts deep sleep and has been known to result in chronic stress and depressed immune function and triggering behavioral abnormalities).
Nocturnal reptile light bulbs should produce a dim light.
They are generally available at higher wattages than the regular decorative red, green or blue incandescent lights you can find at hardware and lighting stores. "
"Lighting and heating for reptiles"

Infra red bulbs are designed to provide a "radiant heat",
if one just wishes to provide light,
with minimum amount of heat generation, there are better choices available.
If "night light" is desired, bulbs made specifically for reptiles can be a good choice, but any red, blue or green bulb that is opaque or frosted will do.
Stay away from the clear colored bulbs as they tend to be way too bright.
I use incandescent 25 watt, colored " party bulbs" in my snake room at night, (on a timer), as a light source.
Also available are 8 watt red, green or blue bulbs that screw into a standard light bulb type fixture setup that will provide low level (night) light with relatively minimal heat generation... mega hardware, lighting stores probably, most likely stock 'em.
Minimum/ maximum thermometers are very important/ crucial if one decides to provide a basking spot.
One should be aware of the very real possibility of broiling/ roasting ones Corn Snake, if radiant heat sources are by chance, setup wrong.
