Why normal incandescence lamps marked with Power in Watt's and not lumen?

Because lamps and sockets can only support so much current and heat. The box often DOES say lumens.

ie: the 50W bulbs I have are marked as 820 lumen

I have never seen a filament bulb box that listed lumens. Same with flashlights. They guard that information like it's fort Knox. Then when they do give it to you, you can't mentally compare because no one else does.

i've got a 4 pack of GE 75W incandescents that clearly says 1150 lumens

Damn 46$ for lamp is alot.

Edit: oh it say's save up to 46 lol...

We haven't had any go yet, had them in for about a year. Used to spend a stupid amount of time replacing incandescents that seemed to go all the time, so it's a wonderful change

The Philips spiral ones seem to be the best for replacing conventional bulbs, the straight ones leave a bit of a dead spot below them.

Colour is great (some warm tone) too

I want to replace the flood lights in my kitchen but they are on a dimmer and the dimmable CFL's are like $10 each or about 2x the price of the standard replacements. I may take off the dimmer switch but I like the ability to control the light in the kitchen at night time. It's an open floor plan with our family room, etc. Maybe something else in the future will be a better option.

I had another CFL that burned out that looked like it short circuited and had burn marks on it. My wife was paranoid the house would burn down if we continued to use them so I was unable to buy them for a while... until recently when I found out that there is a fuse inside the base that is designed to burn out in certain condtitions.

The more you know.

Yeah also one good thing about them is that they dont blink like ordinary lamps so your eyes dont get tired to fast.
Though my table lamp that is FL too and works with from DC adapter is blinking for some reason (you can see it with digital camera, need to lower shutter speed...), and that philips CFL lamp that works from AC socket does not blink, strange, i were thinking you need some special adapter to make it work stable, they probably fit something in lamp itself.

Then look more closley and pay atention to what you read. It'son there, has been for decades.

If Fort Knox was guarded like this, it'd be fort knocked over daily:

Maybe, in america in europe and with cheaper manufacturer's i hardly get to see a box at all, they usually sell bulky lamps.
