Our kitchen ceiling lighting, 6 floods, went from 360W down to 42W!
The other thing I've done is installed motion/occupancy detectors on rooms that tend to have their lights left on... 4 rooms: one powder room, laundry, hallway from garage, master closet... 1st month's savings in electricity, $6... so payback in one year... going to add three more to walk-in closets. ...Jim Thompson

It's what you learn, after you know it all, that counts.
Oh, if price is not an object, how about two lnd150s with two back to back leds. you could add an R to reduce current, or get crappy leds. The to-92 style are easy to solder.

We love it. You can stand in the shower with hot water pouring on your head and look through that big window at the trees and the snow falling outside. The window is the visual center. Fabulous shower head, somehow gets around the water flow restrictions.
One objective was to not have a lot of storage or shelves where guests can leave/donate all their junk. That open thing below the sink was custom made from reclaimed Douglas fir, and only has room for a few rolled-up towels and maybe a small basket with spare soap or something.
This is a cabin, and we pushed back against fru-fru high-tech stuff that would be out of place.

The cap would be 1 uF or less. I don't think a 15 amp wall switch will mind shorting that out.

I want to dimly light up the 120V LED bulb that's already in the overhead fixture in the shower. I can't run more wires.

Keep a bucket in the bedroom and pee there.
It is for me.

Perhaps glass doors are not all they are CRACKED up to be..
Am I missing something?
1) This is an area where water and people will be present. 2) You are suggesting modifying the switch so that the circuit cannot be switched off, and will always be live.Hmmm.
How about glow-in-the-dark tape? I've used that on some door edges (it's not noticeable during the day, but a dark-adapted eye sees it clearly).
It would be amusing to hide some UV nightlights in innocuous places, like behind a light switch plate, both so you can find the switch, and to keep the phosphors on the opposite side of the room pumped up.
The winter was very mild, with light rain in mid-January followed
small hours of the night. This always happens in January. We'll
It certainly will. Calculate peak i.

If you want you can use a 2 or 3 way switchbank to get an assortment of light levels including off

I was going to ski today, but it's 4F (-15C) here in Sunny California. Maybe later.
Weather includes a lot of 1/f noise. It's tempting to look for structure, but it's mostly noise.

Actually, the official US Weather Bureau temp is -6F. It's actually +4 everywhere else.
The official temp gage is usually the outlier. Or liar.

The official figures here seldom - if ever - agree with my own measurements here too. They're always more extreme. I suppose a lot depends on where the sensors are located. Still, the published temps are always more extreme than what most people feel in various parts of the town.
I have some fairly accurate thermometers, calibrated to +/- a few tenths of a degree, and I take the measurements in the shade, away from direct sources of radiation and several feet above ground.
I have a 1K thinfilm platinum RTD, located under a wooden stairway on the north side of the cabin, near an unheated garage. The measurement is ratiometric against a thinfilm resistor and it's calibrated at ice point, probably +-0.1C. Yes, this is compulsive.
It is fun to get time-series graphs of indoor and outdoor temps.
The official weather station here is usually the high or low outlier, by as much a 10F sometimes. Manufactured climate extremes.

Like I said earlier, forget about measuring air temperature. It can vary by tens of degrees from day to night, cloudy to suuny days, morning to afternoon, summner to winter.
Water is a good heat sink. Measure the ocean temperatures instead.
