The gear is plugged in to a wall socket and a couple of extension cords that run from the wall socket that inside the stand area up the right side cabinetry that the tank now covers. the inside of that area has all the ballasts and tunze transformers, aqua III, multicontroller etc.
I hoist the lights up and down with a bike hoist. the 4 adjustable steel cables are still attached but I don't use those anymore other than as the lowest setting when using the bike pulley.
the lumenmax III's do have a much wider spread without the obvious hot spot of the optix III's. I like them.
