HI Folks, I am new to the game of reptiles and currently in the process of setting up an enclosure and a little unsure as to the correct wattage ratting for these Ceramic Heat Lamp Emitters to use. As your are aware they come in 60,75,100,150 and 250-watt ratings. Is it best to use the larger 250 watt as it is on for shorter periods of time, hence more energy efficient and longer life of the lamp etc and a quicker heating time. Or is there more to it. The enclosure is to house a Spotted Python and is Approx. 4ft x 4ft. A thermostat would regulate the temperature. Any suggestions would be appreciated thanks.
