It's perfectly all right for the temperature to drop down to 70 during the night. Lower temperatures encourage them to sleep, and it's more natural. Especially during the summer, if you live in a place that gets around 80 to 90 degrees during this season, there is little reason to live the lamp on at night.
I have the most ridiculous system right now, because where I live, the temperatures are different every day. My tank is way to small for a water heater right now. So, at night, if the room temperature is too warm, I shut the lamp off. If the room temp drops between 65 and 70, I leave the lamp on. If it just gets way too warm that it raises the normal temp too high (Normal temp is 75 to 76) I will take out a few cups of water, and replace it with a few cups of straight cold water. That effects the temperature dramatically, then all the planets align and somehow the room temp plus the lamp keeps the water back at 75 to 76. Basically, the amount of warm or cold water you add, can effect the temperature between 5 and 10 degrees, depending on the size of your tank.
