EXO TERRA makes a ceramic heat emitter ( I use the 100w version ) it puts out heat ...it's a ceramic element....but puts out no light (scorp friendly) I use it in my 10 gal tank. I also have a terrarium heat pad on the same end, so that one end is warm and the other side is cooler, both are connected to a ZOO MED REPI TEMP 500R THERMOSTAT that is used to regulate the temp...works great for my emp, but have to mist more often as things tend to dry out faster....hope this helps...good luck.
