You definitely need a basking light.
Komodo Ceramic heaters provide excellent levels of heat but emit no light. The Komodo White Ceramic Heat Emitter provides an efficient radiant heat source which creates a natural sun-like heat without visible light.
Beardies need the white light as well as heat.
This makes ceramic heaters ideal for enclosures that require a proper photoperiod with nighttime and daytime elements.
This means that if your animal needs it to be dark for a period of the day (i.e., night)- as beardies do- but still warm, the ceramic heater can do that. It emits no light, which makes it different than the red lights you often see marketed as night lighting.
Suitable for 24 hour use, they are ideal for constant radiant heat to simulate desert or tropical environments and help to increase the ambient air temperature to warm the skin, scales & bodies of reptiles.
They're suitable for 24 hour use but you only need them 24 hours if your tank is in an environment where the basking light isn't sufficient for heating. Usually in a particularly cold home/building.
This product must always be used in conjunction with a thermostat.
That doesn't mean ONLY in conjunction with a thermostat. It means it also needs a thermostat so that you can control the amount of heat it emits.
It is being used with a thermostat and sensor set at 85 degrees. It is on a 12 hour timer along with the uv strip light.
It's good that you have a UVB tube light, but he also needs a bright white basking light.
During the night they both go off and he has nothing. Temp is ok here. The warmer side of tank is around 85and the cooler side 70. I turned the thermostat up to 88 earlier and the the little man was opening his mouth whilst basking? But he never moves himself away from it.
The warmer side needs to be much warmer. He needs a basking spot to reach 100-110. The cool side is fine. Eighty-five with no light is not adequate at all.
I hope that helps clarify your heater's instructions.
