Which is why I linked an article that included a watts/lumens conversion chart.

LED bulb packages are required to list lumens. the 100w equivalent would be 1500-1600lm. That's not to say that package ratings are reliable, but that's a different story.

FWIW - the few CFL bulbs I purchased all under performed their ratings, both in output and service life. Which is why I resisted CFL as much as possible. OTOH - all the LED bulbs I've bought seemed to be pretty close to the rating (by eye) and I can't say anything about service life since none have burned out yet.

I'm not a wisconsin utilities customer, so that's not an option.
But in a deal almost as good, Dollar Tree sells LED bulbs for a buck. I've had some of mine over a year and so far so good.
I buy them in store, locally.

Two summers ago I replaced every single incandescent bulb in my house, with two exceptions. Not a problem at all. Exceptions were two outside dimming bulbs that just flickered, even though they were “dimmable”. I think they are more like the old 3 way bulbs. Levels of dimness, not a smooth scale.

Anyway, I haven’t had to replace a bulb since. My electric bill is a little lower. I have no RFI EMI issues that I detect.

I bought some florescent bulb pop-in replacements, but they didn’t last long. Probably the 1953 fixtures I put them in. I have replaced one with an led strip light assy that is quite bright.

Last summer I replaced my navigation lights on my pontoon with leds. Much much brighter, should last a long time, and not draw down the battery as quick during those night fishing marathons.

I'm stuck on the issue of I have a lot of incandescent bulbs that are still going strong and most of my lighting is recessed floods on dimmers. When 1 or 2 go out, I'll replace the entire room with dimmable LEDs so they all look the same, but those bulbs are about $4 each cheapest I can find, so it'll take 3-4 years to save in energy costs what it costs to replace them before they were due (and now I have a closet full of incandescent indoor floods that I feel incredibly wasteful throwing away).

I also have the problem that the rest of my regular sized bulbs that I haven't replaced (I've done as many as I can) are all in fully enclosed fixtures (kid's bedroom overhead lights, bathroom ventfan/light combos, garage door opener) and just about every LED I've found says it's not for fully enclosed fixtures. I can't really figure out why that would be. At least to my basic knowledge of energetics, electricity goes into the bulb and gets converted to light and heat. If the LED takes in less electricity but puts out the same amount of light, there should be less energy left over to convert into heat. So why can't they be in a fully enclosed space? It seems like heat dissipation should be an issue.
