Wait for full brightness... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... .... ....Ping. In case you missed it in the other branch... Fluorescent bulbs (CFLs) have a high individual environmental cost compared with the traditional incandescent bulbs.[1] Each CFL contains about 5 mg of mercury, phosphors, a PCB full of semiconductors, several metres of copper wire in its coil, several plastic mouldings, complex glass work and numerous metal parts, and the manufacturing process has many times the CO2 footprint of that for conventional bulbs. Real-world CFL life expectancy is nowhere near as long as the projections based on unrepresentative test cycles. At the end of their life CFLs need to be carefully disposed of via specialist facilities. About half of the CFL projected energy savings (to do with less heat generation) don't apply in temperate climates such as ours. Old people are being advised to leave CFLs on all night where they used to turn off the old ones - because of the lack of light during the warm-up delay. Many people are finding that where one bulb sufficed before, they now need two or more CFLs. The CFLs have been linked to various health problems related to "electro-smog". For more see: http://peswiki.com/index.php/Directory:Compact_Fluorescent_Lighting_%28CFL%29_D ownsides [1] Light bulbs don't emit CO2, power generation /may/ depending on how it is generated - and it will be increasingly from sustainable sources in the future anyway. -- Matt B |

And we all know what the likely environmental consequences of that ill-conceived Euro initiative are going to be! And what is wrong with using lighting that has a higher efficiency of converting electricity into lumens of useable light, rather than wasting it as heat? The theory and the principle are fine, but the reality will inevitably be different. [snip] For more see: http://peswiki.com/index.php/Directory:Compact_Fluorescent_Lighting_%28CFL%29_D ownsides Whilst accepting that there are considerations that moderate the magnitude of the difference I don't see anything in that list that offers a compelling argument in favour of retaining less efficient incandescent lighting. Certainly many of the so called health issues are either ones that are poorly documented and somewhat controversial or are in themselves of a limited impact. Indeed many of the issues seem themselves to be of a largely "theoretical" or even I would suggest "hypothetical" nature. For example the UV hazard from a flourescent bult is only a very very small fraction of the UV hazard from exposure to sunlight. Spend one extra minute a day out doors for every few hours of exposure in doors to get the same UV exposure. Also with regard to the chemical hazards such as are involved in the PCBs and wiring. In the average home there are numerous electronic devices such as phones, chargers, televisions, computers, games consoles, cameras, toasters, food processors etc etc. So what proportion of that is contributed by low energy lights. As mentioned before I've already made the transition myself from incandescent to a mixture of flourescent and LED lighting solutions and I don't have personal experience of the problems that are listed. Indeed the LED lights I now have for my bicycle are many times better than the incandescent lights I used to use. Similarly for camping, walking and caving.

LED is hugely better obviously for portable lights, but I can't see any compelling reasons not to use incandescent lights at home where electric power is cheap and plentiful-- besides lights are mostly on in the winter and you've got to heat your house anyway. If there were compelling reasons they wouldn't have banned them-- people would have just all switched to CFLs anyway. |

Electricity is a very expensive way of heating a house. Anyway the heat is largely emitted as hot air at high level, which is not much use. Quite how much heating a 60W light bulb provides compared to a 2500W radiator is left an exercise for the reader. -- David Hansen, Edinburgh I will *always* explain revoked encryption keys, unless RIP prevents me http://www.opsi.gov.uk/acts/acts2000/00023--e.htm#54 |

Yeah. There are NO SPEED CAMERAS on the moon, and also, there are no pedestrian fatalities. That proves it. Stands to reason. You'll need to do better than that. Well... yes... but there was someone posting bhere just last week along the lines: "You can't prove that x is not the case, therefore x must be the case". Up to a point, Lord Copper. What I ACTUALLY said is: There is evidence of X There is no evidwence of not X not quite: we were discussing risk compensation and cycle helmets - I said there was no evidence that such relationship existed. I asked you for evidence "that there is a risk compensation effect when wearing a cycle helmet?" You insisted I provide evidence that "users of cycle helmets are/not/ affected by risk compensation" It was pointed out - I believe by Mr Nugent - how stupid this request was. You get quite cross because Mr Nugent made you look quite silly. -- Latest DfT Figures: Passenger casualty rates by mode Per billion passenger kilometers: Killed or seriously injured: Pedal Cyclists : 527 Pedestrians 371 All casualties: Pedal Cyclists : 3494 Pedestrians : 1631 Which is more dangerous? |
