There is an abundance of energy-saving light bulbs on the market, but they are not all readily available nor are their facts. Even with numerous "TIPS" being published lately on energy saving bulbs you still don't get the necessary details to make the correct purchase.
Our objective is to provide you with those details and one way is with a comprehensive Bulb Chart so that you can have a clear understanding of the different watts energy saving light bulbs have.
First the basics: How many watts do you buy when replacing an old light bulb?
If you don't replace with the correct wattage and correct design, you will get the wrong amount of light and the wrong distribution of light.
Failure to address these steps appropriately means you
will not maximize your savings!
The following guide is generalized, but you will be well advised. Details such as Lumens and Light Color will follow later throughout this section with links, such as the two in this sentence, thus helping to get maximum savings.
