Looks awesome. I added a topper to my canopy when I added the halides. My first canopy was 5 1/2" off the water. I added a 1x10 to the top so my lights are now about 9" off the water. The bulbs will hang a bit.
My canopy was not so intricate though. There is a few places on ebay eith decent canopy prices. Might need another road trip
