Anyone here make their own ballasts? Years ago when I had my 180g set up, I ran my own DIY ballasts similar to these - https://lbu-main-lightbulbu.netdna-...75_watt_metal_halide_ballast_kit_quad_tap.jpg
The problem is that my brain has not retained the information necessary to build them from scratch. It's hard to pass up $35 ballasts when made yourself, other than paying $100+ for a big heat sink with a brand name on it.
