The gun should be held only 2" away from the area you're checking. If you could retake the temps again, that would be helpful.
With those measurements of 36L x 10 x 16H, it's only a 25 gallon tank so it seems like your temperature gun isn't giving you good readings. Would be a good idea to drop down to a 75 watt household light bulb (not the compact type) and then recheck the temps.
Would you be able to post a picture of your setup for us so we can help further? How old or what length is your beardie?
