I am brand new to Christmas Lights and decorating. So brand new that I don't even have anything purchased yet. I would like to buy some lights but I don't even know where to begin or where to buy them at. I have been checking home depot, lowes, and menards but have the time, the online specifications don't say if they are dimmable or not, and from what I have been reading it is best to have dimmable lights for a good display. I did read in one of the forums that Walmart actually had a good selection to choose from, but once again, where do I start and what do I buy in regards to LED lights?
