— priorities

1. priority: enough brightness at each location, so we need no additional
2. priority: the forgetable lights need to be low wattage, perhaps due to inconvenient location of switch. Eg: peripheral lights when fan lights on!
3. priority: the most used lamps should be most efficient, not necessarily lowest wattage
4. LGLp: avoid wasting bulbs? See note below.

— Now the locations, half-ranked by hours of usage each week, based on subjective estimates

1. above dining table [8w LED]
2. two fan-lights 5w each
3. sofa peripheral [8-14]w… used during day time ! easily forgotten. Currently too dim.
   • The piano side: Need similar brightness as the other side, or remove completely.
4. —-
5. above kitchen sink [9w LED]. Only during cooking
6. [m] room2 wall [4-15]. Changed to 5.5w on 30 Sep
7. [m] cockpit1 [4-8-20]. Go lower with usage !
8. master room wall light [4->11-20]
9. [m] fridge-side should be [9-20]w … currently too dim
10. laundry ceiling
11. [m] 3rd fan light — less used
12. [m=mostly used by me, not family family]

— at night, which one light I can keep on?
cockpit1?
— too many bulbs at home? I do have too many bulbs at home. If needed, leave the inefficient bulbs as spares, or give them away if new

Perhaps shelve the energy-inefficient, legacy tubes. They don’t seem to have a place in our current home (or next home)
— Ikea LED bulbs have best prices: about $4/2,
Also the highest efficiency, more than 100 lm/w
