Green Lighting: The Lightbulb is on But is Anyone Home?

I have switched most of the lights in my house to Compact Fluorescent Lights or CFLs, I knew it saved energy and that it was good for the environment but exactly how good, well I hadn’t a clue. Recently I read this article about CFLs and what I found out will hopefully make you want to change your light bulbs to CFLs also.


1. CFLs are four times more efficient and last up to 10 times longer than incandescents.

2. CFLs use 50-80% less energy than incandescents.

3. CFLs use 1/3 the electricity saving you money in the long run.

4. Replacing a single incandescent bulb with a CFL will keep a half-ton of CO2 out of the atmosphere over the life of the bulb reducing air and water pollution.

5. CFLs are very versatile. They now make 3 way and dimmable CFLs.

Here are some helpful hints when looking for the perfect CFL for each room in the house.

Living Room/Dining Room – You will want warmer CFLs where entertaining guests. The yellow and red tints make skin tones and clothing look softer and more inviting. Look for a kelvin range of 2,700 – 3,000.

Study/Workshop – Go with cooler kelvins for task lighting, around 3,500k. The iris contracts in response to a bluish green tint, making it easier to focus on stuff close up.

Bedroom – Go for something warm around a 2,700 k.

Bathroom – A CFL isnt the best option for the bathroom. Its normal lifespan of 10 times that of an incandescent is cut short when it’s turned on and off frequently.

Backyard – A kelvin of 3,000 is perfect for the outdoor lighting, it adds warmth and a good amount of light.
