Depends on the room and time of day. Warm/2700k for night and bedroom, living room. Daylight/5000k or higher for kitchen daytime/warm night time (3-way switch for different bulbs). They're now making easily temp-switchable LED bulbs with a whole range of four or five settings--might check those out. e.g.: https://www.costco.com/p/-/feit-ele...ed-classic-glass-a19-bulbs-12-pack/4000436427
None of them, lol. I hate flying so I try to visit them as little as possible and frankly only know three. But! If I were to chose one anyway I would pick a military one (more of an airbase) as I prefer those aircraft - RAF Fairford as that's where they hold RIAT.
