As long as it gives off adequate heat, you should be fine with a household bulb as a basking light. Nothing coloured though, bright white is preferable (ideally between 4000-5000 on the Kelvin scale). The brighter white light helps better protect lizardy eyes from the UVB radiation
EDIT: Also, I'd suggest avoiding Repti Glo UVB bulbs - even the tube ones. I know from experience that they can cause various health issues in bearded dragons, like conjunctivitis and decreased appetite. Reptisun (10.0) or Arcadia (12%) are much better choices for UVB!
