So does this mean that I will have to start cleaning my light bulbs when I clean my computer (Dusting the fan)?

that might be the coolest comparison I have ever heard. 5 watts might make me invest in lightbulbs

Hello! Michael...I recently bought CFL, I had no idea there were so many choices. Very, very informative presentation. I learned so much. Keny

Hi Michael, I have used CFL's for years. They helped me lower my power bill a lot over the price of regular bulbs. As a matter of fact I can light my entire house on a total of less than 75 watts. AWESOME! I can't wait to try the new LED bulbs out. I need to find someone in my area that actually carrys them. Then of course there is the price. I hope they start to drop a bit soon. No offense but $79 for a bulb is a bit pricy, does it come with a guarantee? Peace Bryan kc8hps_2003@yahoo.com

While this is a great comparison of existing technologies I feel it is a bit misleading. All he is comparing is power consumption. What he should be comparing is power consumption per lumen. The LEDs may only use half as much power, but they only put out half as much light. CFL's are so much brighter, so I'll stick with them for now. It is nice to see what else is being developed though.

Ahh, the marvels of modern technology! Are we going to see those, I believe (correct me if I'm wrong) LCD bulbs that are excited by a laser beam and shine for, how long, soon?

I am hoping the led lites will be avail for my motorhome/12v application,the battery would last the entire trip and then some. I see a business opportunity here

PS. Maybe a nuclear powered bulb that could not only supply any amount of brightness you could want, but could also put power back into the power grid as well. Food for thought but never will happen due to obvious dangers and abuse

My family owns a restaurant in illinois and we changed all of our bulbs to CFLs which is a good 200 light bulbs, were saving TONS of money don't have to rent a 30 foot ladder to change them anymore! Simply amazing

I'm excited to see that there are finally LED's on the market that can replace incandescents. I was at a physics conference recently and one of the scientists presented her research showing that the light quality of LED's had finally surpassed CFL's. I believe that LED's are where CFL's were several years ago on their cost curve. I'm sure the high cost of the 40 and 60 watt equivalency bulbs will come down. So if consumers can afford it now, or wait a little while until prices fall, we can have more efficient lighting than CFL's and without the mercury! Why is WFAA running adds for people to run out and buy CFL's?!!! People that see those ads, that don't mention the mercury content, will get bulbs that will help the environment from an energy stand point, but will have the potential for poisoning themselves that the environment due to the mercury content. Go LED!

Rick posted earlier that the comparisons were misleading because they were just based on power consumption, not power consumption per lumen. Later in the video that comparison was made. 40 watt equivalent means that the light output is equivalent to a 40 watt incandescent bulb. The CFL 40 watt equivalent bulb demonstrated pulled 14 watts, while the LED 40 watt equivalent bulb pulled only 5 watts, almost a third less for the same light!

SPSalum, don't get me wrong, I'm all for LEDs. They are more efficient than the CFLs. I'm just saying that the guy in the video is saying that they are significantly more efficient, when they are acutally just a little bit more efficient (given the same light output). The chart below shows the number of watts the guy reported and the lumens they put out. I got the lumens numbers from the links for the different bulbs provided. Incandescent Bulb 39 watts 460 lumens CFL 14 watts 700-800 lumens EarthLED CL-3 3 watts 200 lumens EarthLED Zetalux 5 watts 400 lumens EarthLED Evolux S 10 watts 1000 lumens Using these numbers, to get the same amount of light from the CL-3 as you do from the CFL, you need 4 of them, which would pull a total of 12 watts. You'd need 2 of the Zetalux's for 10 watts. So it isn't quite as efficient as he's making it out to be. The Evolux S is an awesome bulb, it just cost a fortune. Again THE LEDs ARE STILL MORE EFFICIENT, just not as much as he says. I just want people to know what they're getting if they are thinking of switching over. Just because a manufacturer says a LED is a 40 watt incandescent equivalent, doesn't mean it actually is. You have to look at the brightness of the bulb. I'll be switching to LEDs as soon as the cost comes down a bit, or when my CFLs die, whichever comes first.
