Got my boa, now for some care questions

[sdiamond808]

Went with a kahl sunglow female, about 1 year old. Couple of questions:

1. Guy tried to sell me a zoomed red night bulb for a little heat at night. I read that the light disrupts them, zoomed bulb claims it doesn't. What is the truth?

2. UVB, I read new information saying they can benefit from UVB, and also that it enhances their color. Any truth to this?

3. LED hoods with blue moon light. Does this interrupt a snakes sleep? They look cool at night, but I do not want to do anything that will mess with it.

4. some care guides are recommending vitamin supplements and calcium with low d3. Do I need this?

5. Also, I read about fluctuating humidity instead of keeping it constant. I am good about keeping it constant but I read this promotes mold. What kind of fluctuations am I looking for and how long at certain levels?

Any help is appreciated. I want to give her the good life.

Thanks,
