"I can't remember now. I'm still trying to recall which filaments worked best in
our incandescent light bulbs"...

Halogen Incandescents, (if you're not going to use normal [tungsen]
incandescents) for sure, natural, slightly yellowish light. Worth putting up with
the occaisional police 'copter hovering loudly over your dwelling (trying to
determine if it's a 'growers house' - remember that Roy Scheider scene in
'Blue Thunder? } welcome to the future.).
LED still strike me as a bit harsh in light output - like looking at a late model
cars' headlights.
