The author of this blog purchased as 3-pack of LED bulbs expecting them to be the same but they are not. One bulb emits a pink spectrum of light, one shines light yellow and one has a white-green coloring to it. Most people would take them back for a refund or replacement but not this author of the Save Energy Blog. The bulbs serve as reminders that even when you specifically purchase energy efficient products you sometimes do not get the consistency or results you expect.

You are probably thinking that these are generic cheap LED bulbs but actually they are made by a famous name brand bulb manufacturer purchased at Home Depot with the GU10 base, so they are relatively expensive bulbs to boot. The fact that the three supposedly identical bulbs emit visibly different spectrums of light highlights the following issues:

Replacing an industry staple, such as the incandescent light bulb, with more efficient versions can sometimes produce unexpected and even undesirable results.

If you cannot expect a basic item like a light bulb to perform within expectations then how can you expect larger purchases, such as heating or cooling systems or refrigerators, to perform within stated parameters?

This is not to say that all energy efficient products have inherent problems or should be avoided. The addition of a 3rd party certification or label from ENERGY STARĀ® or other program can be helpful but it is also smart to perform some personal research as well.

The purpose of the Save Energy Blog is to explore promising energy efficient and clean energy products, technologies and strategies. The emergence of artificial intelligence (AI) and smart devices for buildings and transportation offer new opportunities to get things done while reducing wasted time, energy and money.
