So a lot of people don't think about Light bulbs falling within the realm of Interior Design - but lighting can make all the difference - and the type of lighting that you choose not only affects the brightness, utility and overall mood of the room, but it also affects your wallet! And we all know that more money in the wallet means more money towards the gorgeous light fixture these light bulbs will be going in. And as energy efficiency and lifespan become more and more important, the incandescent bulbs we're so used to will start becoming a thing of the past. And even though most of us are still reluctant to make the change (nearly 90% of all households still use incandescent bulbs according to a new report by WBUR), new legislation aiming to reduce energy consumption by 2012 is helping to make the change for us. And if you're wondering what all the fuss is about incandescents and why they're not as eco-friendly as other lighting options, it's because the way they create light is by heating up a filament until it's so hot it emits a glow. It works - except that most of the energy used is to create heat, and since this heat doesn't actually translate into anything, it's just lost into the atmosphere, wasting most of the energy required to generate that 60W of light.Compact Fluorescent Light bulbs, also known as CFLs, use a different technology, requiring 60-80% less energy to put out the same amount of light so that a 13W CFL is equal to a 60W incandescent. They also don't generate as much heat and last a whole lot longer. Most of the objections to Compact Fluorescent start with their 'unsightly' shape - that coiled look is definitely something I don't want to look at through a glass light fixture - but thank goodness the manufacturers started catching on and you can now get more 'bulb' like fixtures in opaque glass. And frankly, if it's under a shade and out of sight, there's no need to worry about what your bulb looks like.

Another objection is the kind of light they give off. It's definitely different from the warm yellow-ish light we're used to from incandescents. Instead, it's whiter, and it took a little while for me to get used to when I made the switch a couple of years ago - but now the technology is so much better that they have options for 'white' or 'soft white' and if you read the labels, the bulbs labeled 2700K emit light very similar to an incandescent. They even have ones compatible with dimmers.

The other issue is cost - these bulbs are more expensive and a few years ago, buying 1 bulb could have been anywhere around $15 - but now, prices are more like $1.50 - and it's worth it. That one $1.50 bulb can save you so much energy over its life span that you'll actually be saving somewhere around $30-50 per bulb!!! The downside to these bulbs is their use of mercury - but luckily the amounts are negligible, and if you recycle it (as you should!), this is dealt with properly and helps to prevent toxic chemicals getting into our soil and water.
The new 'it' thing with lighting is the Light Emitting Diode, otherwise known as LED. LED lighting is energy efficient, long lasting and directional - so when you point a light at something, that is where the light actually goes (unlike incandescents or even CFLs that sort of spread light all over the place). An LED light uses only about 2-3W to put out the same amount of light as a 60W incandescent...now that is definitely quite a savings. It also lasts about 30,000 hours - that's about 12 years. I haven't even lived in a home for 12 years since the very first home I grew up in! Although LEDs give off a much cooler light, they actually are more similar to daylight, are easier on your eyes, and even can help to enhance your mood. LEDs also mix well with natural light.
Above the GeoBulb, available from Bio-Enviro, offers a '60W' equivalent bulb in 3 colors of light that require less than 8W while giving off 14% more light than its incandescent counterpart. It's also made to last - 10 years in fact, if you use it fr 8 ours a day, every day of the year. LED lighting is also as flexible as incandescents so you don't have to give up your fabulous holiday decor - this solar powered string of lights uses LEDs.
