From Orpheks website. Using a dimmer or other electronic control shortens LED lifespan by up to 60%. Not sure why such a statement was made but it just goes to show you can't always believe what you read. Apparently their is no truth to that statement but for me when I was buying this fixture I thought the KISS method was a far safer path. I guess we will know soon enough.I am by no means an electrician or led pro.Quite the contrary; I was just relying on what I thought would be experts of some sort.
