Wattage depends on the size of the tank and the temps you want to achieve. If it's a 20 gallon, a 60 or 75 watt should be fine. I'd cover the top to keep the heat from rising out. I have a regular 75 watt bulb on a 10 gallon and without reflectix, it stays around 76 on the cool end, but with reflectix, it gets up to 83 or so. That way, I can make more use of the heat put out, without raising the wattage

I'd keep all heat sources on one side. That way you have something of a gradient that your sand boa can use to thermoregulate.
