We picked these lights for our backyard. I ordered a mix of the 1 and 2 watt but I couldnt really tell the difference. Still, these are very bright so we use a dimmer which created great ambient mood lighting. I would have saved the cost on the 2 watt and just ordered the 1 watt which are cheaper. I purchased 7 strands of these and the price and quality are phenomenal. These looks fab in our backyard.
