Enclosed bulb hot environment, CFL or LED better

Look for some that are rated for use in enclosed fixtures.

Actually, I did look at my local home depot for that.  They didn't have them.  I was there shopping for a run of the mill toilet tank inlet hose, they didn't have that either.  I'll have to hunt again later.

It could be because of the spring time (gardening needs and people like myself fixing things up after the winter); adding to that we are still in semi-lock down.

Irony, while people are home with time on their hands to fix various things, the tools and parts are hard to get...

There are some supply line disruptions still but I suspect a lot of it is exactly what you say, a lot of people are home, the ones who are working from home have a lot of time they aren't spending commuting and have motivation to do projects that make it easier for them to work at home, this leads to shortages. Things like closet shelving parts have been pretty well picked over every time I've been to the local big box home center.

Have you considered a wall wart (rated to twice the current you actually need) plugged into the light socket using an adapter powering some LED strips?

Yes I have - in fact, I got a pair of the LED strips already (240 per strip @ about 900mA), but wife didn't like the idea of having strips on the wall.  I could keeping them in the bowl but the dots of bright randomly placed inside the bowl looked awkward.

So, I have a pair of strips unused.  As soon as I get around to it, I plan to make a few long alligator clip cords to use the pair as emergency light with my car's jump-booster as power source.

After see this post, I was more alert.  An infrequent slight blinking my lights a caught my attention (twice, sub-second off then back on).

I know this happened before, frequent enough for me to remember but I never put much thought to it thinking it may be wind-caused tree branches brushing the power line.  We do have frequent (once a year or so) high-wind caused outages.

I have to pay more attention to such quick-blink from now on.  The in-coming power may be less reliable than I thought.

I appreciate that's a pretty standard disclaimer, but did you watch the video? The hack is trivial: just remove a resistor. Since the all the components will be running at a much lower temperature, after the hack, it will theoretically reduce the risk of fire. The only thing you need to be careful of is to securely put it back together again, to eliminate the risk of shock. If there is a fire, how are they going to know the bulb was modified? It's highly unlikely they'll even look at it, unless the fire has clearly originated from the bulb, which is less likely, than if it were unmodified. There are risks with everything and this is one which I think is worth taking
