I use Sylvania floods and spots exclusively now. As far as incandescent basking lights go, there is no difference in output spectrum. The household lights are way cheaper, they last longer, in from my experience, they don't explode in my cages the way the $15 herp lights have in the past.
If you can't find Sylvanias, look for a bulb with the clearest lense possible. Ones with the opaque or frosted lense don't transmit enough heat/light to the basking area.
Revenge is a dish best served cold...
With a side plate of steaming entrails,
And a nice Bordeaux!
