went down in the basement to find my Rhino room smelling like hot wires or something . The rheostat i got at pets smart was so hot it burned my hand . This morning the basking bulb burned out that was hooked up to the rheostat , and i returned it . Now the rheostat . :huh: I have had 8 bulbs a rheostat and a CHE all burn out since i got my rhino . I had a electrician check out the wall sockets in my basement , to see if there was a problem after the first 4 bulbs . All was fine . :huh:
