So far after a month of daily operations, I'm glad to report that none of my LED bulbs seem to be having any problems with MSW inverters. Perhaps because they were designed to handle dimming, they don't seem to freak out when seeing the non-sinusoidal waveform of the msw inverter types.
From an off-grid solar standpoint, that means I can use inexpensive MSW inverters for my lighting, and dedicate the more expensive PSW inverters to most of my other electronic gear.
The prices and availablity are getting really nice. Even my local grocery store stocks either GE or Osram/Sylvania, and pretty cheap when on sale.
I tried early models like Feit and so forth years back and was not too impressed, especially for the price. QC among all the brands seemed shoddy, so I wrote off LED's and stuck to CFL. So be sure to do a little research, and make sure you are not getting hold of new-old-stock.
It is a different world now! Here in earthquake country, I also like the fact that I'm not handling them with kid gloves and potato chips, or will be stepping on toxic junk if the house gets turned over. Heck, I even bought new lampshades!
For us battery geeks, the wide variety of bulbs and wattages makes great dummy-loads for battery bank testing the smaller sized setups.Comment

It is amazing to me that the six or more led bulbs take as much together as one bulb took before.Comment

Even though standard incandescents are now gone, I found "look alikes" from the nearby grocery, which are really just halogen. A bit of power savings compared to incandescent, but what a joke - side by side with led there just isn't any point.
I guess this is to satisfy the customer that "dang it, I want my bulbs to look like those from when I grew up.", even though worse than CFL in power draw!Comment

I'm with you on that. I thought CFL's rocked back in the day, but no more.

There is also the winter time downside, the incandescents provided heat, and the replacements don't. Sometimes this has unexpected consequences.

So I solved that problem and moved to Florida.
Now I only have to worry about hurricanes and rising water levels.Comment

Fortunately you do not work for the State of Florida.
State employees (and presumably contract workers) are prohibited from referring to sea level rise. Instead you only have anomalous high tides.
The average water level is legally prohibited from changing by administrative fiat.

Most of those "heat tapes" were unregulated and would continue to stay hot even if the outside temperature rose back up.
The better "tapes" had a regulating thermostat so they would turn off once the temp got above a preset value.
Both types did used quite a bit of wattage depending on the length of the cable and type used.Comment

Under NEC permanently installed heat tape requires ground fault protection (Class B, not the 6ma threshold of Class A).SunnyBoy 3000 US, 18 BP Solar 175B panels.Comment
