Spit fire - I plan on moving the tank in a few years and wanted to have a solution that worked for both locations with out putting holes all over the place.
I ended up ordering some extruded aluminum to build my light mount. In theory with 1.5" 1515 and 20lbs of weight I should have a max of 0.5" of sag. Now the xr15s are only 4-4.5lbs each so it should be more like 12-13 lbs so I don't suspect there to be any noticeable sag!
Concept has a Black Friday sale which was an excellent excuse to put down a deposit and get an awesome deal on my future tank / sump.
I'm over killing it a bit with 5/8" (15mm) star fire. This thing will be a tank! The display will be 66x20x18. I figure the extra 6" at the end will be used for the light stand/overflow and mp40 dry sides all hidden behind a flush mounted u shapes acrylic cover
