http://www.theglobeandmail.com/servl...archType=Quick COLOUR WATCH: ENERGY ISSUES Shedding some light on CFL bulbs JANICE LINDSAY style@globeandmail.com January 5, 2008 Energy-efficient light bulbs will negatively affect the colour of your walls, your art, your fabrics and your complexion. They will, however, save energy and money. What a dilemma! Light is not just a question of volume - brightness and dimness. It has content - i.e. colour. Daylight has all the colours in the spectrum represented in equal amounts. It looks good and feels good because it is a balanced diet of perfect colour. Artificial light, on the other hand, is usually wonky - fluorescents have more green than daylight, while LEDs have more blue and incandescents more yellow. Full-spectrum lights, often used in spa settings, mimic the content of daylight but can seem a little unnatural in the evening when you want to relax and get cozy. The problem is that the colour of the light affects the colour of an object. And we can see the resulting combination. This is why those trousers that looked black when you left home look navy when you get to the office. It is called metamorism. Most of us have happily gone about building the colour palettes in our homes using natural light augmented by incandescent or halogen lighting. The bit of extra yellow is not really a problem. This light suits our decor but it also suits our psyche; we are biologically disposed to find the light cast by the glow of an incandescent light bulb's heated filament "right." It mimics sunlight and firelight, getting cooler as it gets brighter and warmer as it dims. And we have lived quite happily this way for 100 years, with no one even trying to improve on the reality that more than 90 per cent of the energy used by the bulbs becomes heat, not light. Enter the CFL (compact fluorescent lamp). Everyone fixates on the fact that it is almost 10 times as energy-efficient. Because of this, we are supposed to forget that many fluorescents have a flicker issue that negatively affects some people. They have a start-up time lag so they are not good to use over your stairs if you are always in a rush. Most can't be used outside when it is really cold. Unless you buy a special "three-way" CFL, they can't be dimmed. All contain small amounts of mercury (be very careful if you break one!) so they cannot be thrown out. And, except for Ikea, most stores are happy to sell them but will not take them back for recycling. But worst of all is their light content. They give off a diffuse light, more like a cloudy day than a sunny one, which is depressing. (And if you have the misfortune to spend your days under large swaths of fluorescent lighting, be sure to get away from it on your lunch break. It makes us tired and depressed. To cope with fluorescent light, our endocrine glands pump out cortisol, a stress hormone. When it is exhausted, we are more susceptible to colds and illness.) Even the "soft white" CFLs do not give off the same warm tones and crisp light we are used to. They make existing colours look wrong. Fluorescent lighting is efficient but not sociable. In my experience, it is hard to choose colours that look equally good with fluorescent light and daylight. Incandescents present no such problem. The solution is not skipping CFLs and heading out to get LEDs (light emitting diodes), which are 50 times more energy-efficient and last "forever." They, too, have their problems. The white light is bluish and the intense pinpoint beam is not diffuse enough for most residential situations. Even as Christmas tree lights, they don't sparkle but merely sit like sullen bullets of colour. An LED pot light would be about as pleasant as the beam of a Mercedes-Benz headlight burrowing into your eye. Their long life and energy efficiency makes them wonderful for architectural lighting, light effects, dashboards, small appliances and under-cabinet lights. And some of the possibilities are exciting: as in organic LED lighting in flexible sheets that can be used as luminous wallpaper. I know I am being irresponsible by sticking to my incandescents until someone solves the colour issues of energy-efficient bulbs, but I am willing to compromise. I will use CFLs in utility areas. And my New Year's resolution is to dim or turn off my inefficient lights whenever possible. That will more than quadruple their efficiency. Others may be more stoic and try to get used to the unnatural light of CFLs. But since it took two billion years for us to get used to a warmer and varied light, I'm not optimistic.

Here's a cost saving tip. If you use a 300watt pool light, save some money and use a standard 100watt long life or even standard life. Not a big difference in brightness in the pool and you save energy and initial cost.
Our 100 watt pool light is 2 years old and my son has a habit of turning on the pool light when he goes outside to smoke. Now if I can only get him to stop smoking! Richard Ross Accurate Home Inspections of America, LLC Cape Coral, FL 33914 239-271-8499 Office 239-271-8499 Mobile 407-358-5376 FAX

HEAT OF THE MOMENT
Warning: Vacate room when CFL bulb breaks Energy-saving devices called so dangerous everyone must leave for at least 15 minutes Posted: January 6, 2008 1:00 a.m. Eastern © 2008 WorldNetDaily.com Thomas Edison, inventor of mercury-free light bulbThomas Edison must be rolling over in his grave. Less than a month after the U.S. Congress passed an energy bill banning the incandescent light bulb by 2014, the UK Environment Agency issued guidelines calling for evacuation of any room where an [COLOR=blue! important][FONT='Times New Roman', Georgia, Serif][COLOR=blue! important][FONT='Times New Roman', Georgia, Serif]energy[/FONT][/COLOR][/COLOR]-saving compact fluorescent light bulb is broken, releasing toxic mercury. The warning comes a month before the British government begins its phase-out of tungsten bulbs, scheduled to be completed in 2011. The switchover to CFL bulbs will save at least five million tons of carbon dioxide emissions every year, the government said. Health experts warned this week that people with certain skin ailments will suffer from the new eco-friendly bulbs which cause conditions such as eczema to flare up. Additionally, the bulbs have been linked to migraine headaches in some people. The Environment Agency's latest advice focuses on the 6 to 8 milligrams of toxic [COLOR=blue! important][FONT='Times New Roman', Georgia, Serif][COLOR=blue! important][FONT='Times New Roman', Georgia, Serif]mercury[/FONT][/FONT][/COLOR][/COLOR] in each bulb. Users who break a bulb should vacate the room for at least 15 minutes, the new guidelines say. The debris should not be removed with a vacuum cleaner, which could put toxic dust into the air, but with rubber gloves. The broken glass and all residue is to be placed into a sealed plastic bag and taken to a local official [COLOR=blue! important][FONT='Times New Roman', Georgia, Serif][COLOR=blue! important][FONT='Times New Roman', Georgia, Serif]recycling[/FONT][/FONT][/COLOR][/COLOR] site for proper disposal. Because these light bulbs contain small amounts of mercury, they could cause a problem if disposed of in a normal bin," environmental scientist Dr David Spurgeon told the London Daily Mail. "It is possible that the mercury could be released into the air or from land-fill when they are released into the wider environment. That is a concern, because mercury is a well-known toxic substance." The Environmental Agency noted that neither warnings about the bulbs' toxicity nor directions for proper disposal is printed on any packaging. Such warnings aren't necessary, said one toxicologist who said a number of bulbs would have to be smashed simultaneously before there was a danger. "Mercury accumulates in the body – especially the brain," Dr. David Ray, from the University of Nottingham, told the BBC. "The biggest danger is repeated exposure – a one off exposure is not as potentially dangerous compared to working in a light bulb factory. "If you smash one bulb then that is not too much of a hazard. However, if you broke five bulbs in a small unventilated room then you might be in short term danger." The most-immediate hazard from the CFL bulbs may be to Brits' pocketbooks. It costs about $1,300 to properly dispose of one municipal recycling bin full of bulbs – a figure that is sure to increase residents' tax bills. ...Cookie [/FONT] Need help on inspection call my cell 613-827-2011 I like email Roycooke@hotmail.com Never wrestle with a pig (however titled) as you just get dirty and the pig has all the fun. |

CFL Bulbs
March 15, 2007 ![]() ![]() Does this look normal to you? Believe it or not it is. Sometimes when compact fluorescent light bulbs or CFL bulbs are coming to the end of its life, they shutdown and smoke up. It doesn't always happen but it can and boy does it stink! That's what happened to one viewer who contacted me. The light bulb in the picture is hers. While it looks dangerous the Electical Safety Authority say these light bulbs, unless it's a counterfeit, are safe as long as they're used properly. The problem is there are poor instructions on packages and in some cases no directions whatsoever. So here's a list of don'ts: 1) Do NOT use these bulbs in dimmers unless specified. 2) Do NOT use these bulbs in recessed lights and track lighting unless specified. 3) Do NOT use these bulbs in areas where it goes hot and cold, i.e. cathedral ceilings or outside, unless specified. 4) Do NOT use these bulbs in a bathroom where there is a lot of moisture unless specified There are specific CFL bulbs that you can use in the areas mentioned above. They are more expensive but there should be no price tag on safety. Just make sure you read the instructions or look for pictures on the package. If there are none, contact the manufacturer for proper use. While some bulbs will burn this way, is it acceptable? Electrical Safety Authority (ESA) says NO! ESA is working with manufacturers to improve packaging instructions and improve the way these bulbs end their life. They are hoping these changes will be in effect next year. In the meantime, check out my one-on-one interview with Ted Olechna. He is the provincial code engineer with ESA.
