I share your concerns. I learned about a term "greenwashing" not too long ago that is the act of a company to advertise themselves or one of their products as" green" or simply imply that it is more green that it truly is for monetary gain. It is such hard work to find out which companies are on the up and up and what you have to look for in order to determine their validity. It is very frustrating.
I haven't switched over all of my light bulbs yet, so I will be sure to read this post before I do!
