Why is my bearded dragons heat lamp not working?

i bought a new heat lamp for my bearded dragon the other day and now it is not working...nor is the regular bulb i used while i was waiting to get the proper one!! i have a it linked to a thermostat which seems to not be getting any power either. I dont know what to do as its was a ll set up when i bought the viv and i dont know whats wrong...The bulb hasnt blown because it works on a normal light!! Any help would be great as i dont want me beardie to die but i cant fix it if i dont know what is wrong with it!!
