| Anonymous Coward User ID: 2798886 United States11/29/2012 02:32 PM Report Abusive Post Report Copyright Violation | Something interesting.... I have a solar type fan that fits into the car door to cool the interior. I bought it into the house and put it under a regular light bulb. It ran... I changed the bulb to the "corkscrew" efficient bulb. IT DID NOT RUN. what wavelength of light are these things putting out? |
| Anonymous Coward User ID: 23182389 United States11/29/2012 02:35 PM Report Abusive Post Report Copyright Violation | Home depot has an awesome deal on a 12 watt, 800 lumen Phillips led bulb (soft white)! Package claims a life expectancy of 22.8 years. Reg price was $39. It is on sale now for only $14.98. Quoting: Anonymous Coward 2721566 [link to www.homedepot.ca] For whatever reason their website does not specify this price. As well I don't know if the same deal apples to American customers. It's a great deal though, and on till the end of November. I picked up a couple, then decided to purchase a couple of more, only to learn that they had sold out and that the next truck would be in within a few days. The clerk said that they had sold ten thousand dollars of these led bulbs in a short time (Kelowna store) So they are a hot item.... [link to en.wikipedia.org] 22 years? That's a long time. Will you even be around when it finally burns out? |

I changed the bulb to the "corkscrew" efficient bulb. IT DID NOT RUN. what wavelength of light are these things putting out? the second lamp is fluorescent. solar works by absorbing energy emitted by the heat of the light source. an incandescent bulb is heating that tungsten filament white hot, so there is a huge amount of heat "noise" in that white light. fluorescent is a very cool blue light made by exciting a gas with electricity to a point of over-saturation of the capacity of the valence electrons. it only appears white because of coatings inside the tube. it's the equivalent of the halo light one sees from a tesla coil. it's what gives them their efficiency, but it also renders them "black" as far as a solar cell is concerned. |
| Anonymous Coward User ID: 28147705 United States11/29/2012 03:24 PM Report Abusive Post Report Copyright Violation | LEDs are NOT fluorescent lamps (nor are they incandescent). the article is also flawed because it has been more than a few years since mercury was outlawed for use in fluorescents. if the bulb has the green cap, or green stripe adjacent to the cap, it is a modern non-mercuric lamp. |
