About a year ago I installed a bunch of LEDs at home. I have fixtures that use 40 Watt G10 halogen lamps, which I replaced with 1.5 Watt LEDs that have the same 2 pin connector. The LEDs don't give out nearly as much light, but since I installed a few extra fixtures in each room, I get about the same light level with twice as many bulbs. They're also excellent for hallways, stairwells, inside closets, and inder kitchen cabinets. They give just the right light for small spaces. I have one major problem with LEDs burning out in closed fixtures, which I'll have to replace with fixtures that are open and better ventilated.

You didn't say anything about the mercury that is in the CFLs and what impact that will have on the environment you also didn't say anything about the ECO footprint that goes into the making either the CFL or the LED

Is your name REALLY Hank Green (or green because you are green)? YOUR 79.00 light bulb is so COOL (just for the PUN of it), I would love to own it and save $$$ trudyrodrig@yahoo.com

Beware the mercury in your CFLs, when you eventually do replace them two years down the road! Or, we can ship them off to China, and let them recycle it, as we do (or have already done) with our old tube style CRT monitors. I guess Chinese folks will be less apt to suffer from eco-damage in the recycling process than us :) Note, companies don't recycle the fragile hazardous components in the US, although they claim to! CBS or ABC even had a long special on it.

Enjoyed yr informative comparisons!!! My wife practically had her apartment and our farmhouse converted/dependent on CFL bulbs since we came to appreciate being thrifty with the Philips introduction back in 1984. We still have three very last remaining Philips type serving the kitchen since 1989!!! Yeah & WOOT...;) !!! Good job and I hope ppl begin to realize and appreciate what you initiated with this comparisons... keep us in the loop and btw, I have recently installed one that is so darn bright like a halogen but its a CFL at only 25watts consumption but blinding brightly the entrance to an equivalent of 150watts and it stays so cool, literally too!!!

Do NOT over exaggerate the worry/concerns regarding mercurial presence unless one deliberately smash the bulbs and go fingering the liquid becoming exposed... R U that dumb to do it? I guess NOT. As for LEDs, I find the illumination most fakish and disturbing to the retina for long periods... and I personally won't advise reading under such LED conditions either and its far from romantic as well. great for emergency and camping in a tent... R U living your light years in a tent? Guess NOT again. CFLs for me that are cheaper these days and brighter, quieter and cool for the skin.

I started using some CFLs some 20 years ago they were expensive,fragile circle lights and did not last long. Next I started using the elongated loop bulbs they were cheap, not real bright and a poor fit for alot of fixtures, I would use foil in shades of some fixtures to focus light. They still did not last or stay bright long. The new bulb shaped spiral bulbs produce a much brighter light and seem to last longer, they can still be fragile, these bulbs tend to be dim when fist turned on, not good for a quick trip in the pantry. I now only use about 4-5 incandecents mostly for animal lights (heat), droplights (fall and break bulbs alot). An expensive bulb probably wont be very cost effective. LEDs last long in flash lights, at work an 3Xmas tube sets lit up a window for 1 1/2 years. 12V auto bulbs available at most parts stores

We just got two LED floodlights for our motion sensor light. I think the bulbs were about $30 each, but they'll last a long time and they light up the front porch area like daylight. There's a lot to be said for LED technology.

nice blog!! very informative! how about doing one on some very expensive bulbs(arguably called lamps when they contain rare gasses)! some examples are in the entertainment industry used in computerised lighting and contain gasses such as argon or zenon. some are $200 and up and the lights,(or fixtures),can run upwards of $15,000.

I'm intrigued by the LED technology, and actually tried them. The technology (lumens)isn't quite there to outfit the entire house yet, but they are useful and cost virtually nothing to operate. That said, I do have CFL's throughout the house. If you aren't at least replacing your incandacents with CFLs as they burnout - you are throwing your money away in the long run...

Very good demo. Watts used per Lumen would be more helpful for those of us who use lights to read by. I switched to 100 watt equivalent CFLs in my home about a year ago (using them in 12 fixtures including ceiling mounted highhats that used to have reflevtor floods in them)and am saving about $30/month on me electric bill. Also replaced my hot water tank with a tankless hot water system and that's saving me about another $30/month. Well worth the investment to go GREEN.

Oh, this comparison is awesome! I have been waiting for someone to show the results of this kind of test. I've been saying FOREVER that LEDs are the lighting of the future. Well the future is getting closeer. I use LED bulbs in my night lights. I snatched up two of those Deco bulbs (one "warm" one "bright") first time I saw it. Oh, and don't forget the vivid colors of the LED holiday lights! I lust (well not quite lust) for the day when the brighter bulbs become an affordable replacement for incandescents and CFLs.
