I have never seen more than one or two degree increase to ambient temp with a RHP as it is a RADIANT heat panel this is not unexpected, UTH is also radiant so how physics applies to one and not the other I have never understood. Unless you place a thermometer in direct line with the panel then it is not air temps but radiant temp and the same as surface temp.
Neither Radiant heat panels or UTH do much for ambient air temps. Lights however do a HUGE amount. A basic 2 foot fluorescent light will easily lift 10º-14º over room in a PVCx enclosure and a deep blue LED with internally 110 voltage will lift 8-10º over the room temp. This is way cheaper safer and easier. To my mind in a terrestrial enclosure I would use a UTH and light.
