LEDs use, on average, half the wattage of fluorescents for the same light output.

Summer before last I remodeled the street level lobby of a 43 story skyscraper. During the previous remodel a lot of fluorescent lights were combined on one circuit. When I got there and started looking things over, that 20 amp breaker was running hot and would trip if you just touched the lever. After i got done replacing everything with LEDs it ran nice and cool and no problems.

Fluorescents, even the new T5s, lose light output much more rapidly over their lifespan than LEDs. Plus LEDs typically work much better in cold temps. I can see no reason why anyone would willingly install fluorescent lights any more.

The discussion up to this point was great, and timely, I have been meaning to upgrade my crappy garage lighting for about a year now - so I appreciate all this info;
I was up to reading all this going to look for a screaming deal on a couple to four more used four bulb fluorescent fixtures to wire up with the two I got from my old work...
I currently have two large fluorescent fixtures, and then two other incandescent fixtures;
On cool days, like around this time of year, it is not unusual to turn on the lights, and have the fluorescent lights only starting to turn on by the time I'm readly to leave the garage... it's a little bit of a pain, and had me thinking of having two switches - one for fluorescent, and another for incandescent...

I had to go back to incandescent and CFLs at many places in the house.

I have never heard of this - we use OTA for TV in the house, and I have a radio I am using almost every time I am in the garage for more than ten minutes - so this is potentially a very big deal for me - thanks for sharing this.
