It is not rated by distance the way a heat lamp is, because it works by direct conduction through the glass rather than radiating heat through air.\u003c\/p\u003e\u003ch3\u003eWhich one do I need?\u003c\/h3\u003e\u003cp\u003eMatch the pad to your tank footprint from the table above, and mount it under roughly a third to a half of the floor area — covering the whole base removes the reptile's ability to move away from the heat.\u003c\/p\u003e\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSuitable for:\u003c\/strong\u003e most terrestrial reptiles kept in glass terrariums that benefit from gentle background or belly heat — snakes, many lizards and geckos.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e turtles, aquatic or semi-aquatic setups, or any tank holding water — do not use on or near an aquarium, as the heat can create stress cracks in glass that has water pressure against it.\u003c\/p\u003e\u003ch3\u003eSafety\u003c\/h3\u003e\u003cp\u003eIf room temperature regularly reaches 27°C (80°F) or higher, control the heater with a reptile thermostat rather than running it unregulated, or unplug it. Never enclose the pad or block airflow underneath it — use the included feet to keep the tank elevated. Keep substrate depth to a maximum of about 4 cm (1.5″) for sand or gravel and 5 cm (2″) for other substrates directly above the heated area, and keep the water dish on the opposite side of the tank from the pad. Stop using the pad if it shows cracking, blistering, melting or discolouration, and inspect the cord regularly.\u003c\/p\u003e\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\u003cp\u003eWipe the exterior clean; do not submerge.
