It is our primary goal at MyLEDLightingGuide.com to help our commercial customers save energy and money by using safe, efficient LED lighting for their facilities. It is also our goal to try and educate our customers with real information about LED Lighting, and how to convert from their older style lights over to LED. You won't find a shopping cart on our site. It was our experience previously that what the customer thought he needed was not what he should have purchased. So we would rather take the time to educate and recommend the proper product LED solutions for our customers’ requirements.  For more product information, check out our LED Retrofit Kits at: http://www.myledlightingguide.com/led-retrofit
