A NOTE PROPER DEFINITIONS
BULB - A bulb belongs to a plant, you put it in the ground to grow the plant. A bulb is not a light source. (Bulb @ Wikipedia)
LAMP - It's not something you need to read with, it's actually the illumination product that conducts the electricity to generate a light source. Lamps are used for lighting. (Lamp @ Wikipedia)
LIGHT FIXTURE - This is the fixable equipment (hence, fixture) that connects to the electricity to supply the LAMP that generates the light source. Without it, you'll just have to generate your own static electricity. (Light Fixture @ Wikipedia)
CFL - Refers to Compact Fluorescent as the first letter of compact being "C", the first letter of Fluorescent as "F", and the first letter of lamp as "L". The proper reference would be CFL Lamp, otherwise you are referencing the Canadian Football League and some jock is going to ask you why do you need to screw the CFL into the socket and what the B.C. Lions loosing streak has to do with it. (Compact Fluorescent Lamp @ Wikipedia)
AND NOW, THE REST OF THE STORY
HIP HIP! HORRAY! HIP HIP! HORRAY! HIP HIP! HORRAY!
The last day for B.C. retailers to order old incandescent lamps was yesterday. Today, 2011, is a new era of CFL. If you haven't switched to CFL, you really should - but only as the old lamps burn out.
But I bet you are a little confused. I don't know how @CBCNewsBC can get this article so wrong, they've lead you astray, but a Compact Fluorescent (CFL) lamp is not a "bulb", nor can you place it in the ground to grow a plant. As CBC clearly outlines, improper disposal of a CFL leaches approximately 5mg of Mercury into the ground, poisoning 6,000 gallons of ground water. This would be a major faux pas, so do not follow the CBC's instructions.
SIDEBAR: What the heck? Gallons? REALLY? Last time I checked, CBC stands for Canadian Broadcast Corporation and we converted to the Metric system over 35 years ago. 6,000 gallons, as it were, is actually 27,272 liters. Maybe CBC's Mike Clarke needs to go back and learn the Metric system all over again.
So, now that I've dumped a $#%!load on CBC's inaccuracy, you might be wondering if a CLF lamp can generate the same about of light rendition as a discontinued incandescent lamp. Just because it has 15% energy savings over old lamps, doesn't mean you loose 15% of light rendition, on the contrary, it actually has to do with the number of Watts and the colour temperature of the blub.
The colour what? I know, big hoity-toity designer speak, blah, blah, blah. Let's make it easy: the overall colour of the light - whether it be a yellow light or a blue light - is called the colour temperature, and you can receive both yellow or blue in CFL. It is measured in degrees Kelvin (°K) and the higher the number, the closer it is to daylight. So when shopping for your new CFL lamps, pay attention to what you need - a more daylight feel or more yellowed, jaundice, feel. I love to use all high temperature lamps (and switched 7 years ago to CFL) in my home because this Vancouver winter can be a downer. And yes, I recycle my CFL lamps. I recently had a T5 (tubular) rolling around in my hatch for months until the lovely Jordanne brought it to Home Depot for me. I'll admit, I was confused and couldn't find it.
Rather than trying to explain it all, here's a handy-dandy video:
So, usher in the New Year with a new CFL! But RECYCLE THEM and find location near you at lightcycle.org.
