For my IM 170 (59'', so for ease of math let's round it up to 60'') I got 3 Hydra Edge lights: two 44HD and one 68HD. I'm planning out the spacing for the lights. I assume I don't want equidistant since one of the lights is double the power. So you think The 44s 15'' from the edge and the 68 in the center? Is my math mathing?
