Help with choosing ceramic bulb wattage

[chipdizzle1]

I am getting a 60hx40lx40w reptile one enclosure and want to replicate the tropical conditions in the northern rainforest parts of australia. What wattage bulb would I need to get a temperature of 25-33 degrees? Winter in melbourne gets pretty cold and my house is unheated unless there is someone at home. Thermostat recommendations would be appreciated too.

Also how would I go about getting silicone off the glass of the enclosure?

what animal..

if you must use a ceramic heater, you only want it to act as an ambient temp heater not to create a basking spot, due to the way it heats, it radiates heat which provides heat in all directions, unlike a basking globe which generally directs heat down.
