White light (of any brightness) disrupts sleep patterns...which isn't optimal for health. At the very least, get another light/fixture with a black/red or CHE bulb (CHE gives off no light at all, just heat, but if you have to
regulate it for proper temperature, I've heard they fare much better with an "on/off" thermostat; dimming them is reported to make them fail much faster). The constant use of a white light could be stressing your
snake & harming her health...she cannot express that to you, you have to assume & "read between the lines". If you wouldn't like a white light in your face all night, don't do that to a snake either. I live in a fairly
small rural town & even MY grocery store sells red & black incandescent bulbs, so while LED lights are taking over, you can still find these options. Or go to pet supply for CHE, online or in pet stores.
