for the double bulb fixtures, are you recommending a flat LED replacement (looks like a tennis raquet) or a 4 sided 360deg replacement (looks like an old ladies curler)?
Seems the flat ones would make more sense, but do they put out enough light for the seemingly larger energy consumption than the 4 sided ones.
