So I got in the mail today from petmountain a reptisun terrarium hood with a 10.0 bulb. However upon hooking it up it does not appear to turn on. I insert the 10.0 bulb and turn it a quarter clockwise. Turn it on and nothing happens. I called petmountain and asked for my money back. This was my first time ordering from them and it was not a good initial impression. But before I go off bad mouthing petmountain for sending me defective product the bulb is suppose to emit a visible light correct?
