I bought some standard Philips 0.75kV two-wire ignitors, and ignored the 3rd wire in the fixtures which is just a neutral going to the terminal block. That works just fine, it seems. Flawless ignition of MH.
I'm not going to use these fixtures everyday, they're just really cool because of their sheer scale. They'll be more of a display piece that I'll power up on occasion. It's not realistic to run these as actual lights at home, while they do output incredible amounts of lumens, the power usage would just be too much. I can run one but definitely not more than that.
They do have working power factor correction capacitors, but the capacitive current at startup trips the inverter. They draw 10 amps or something capacitively before the lamps warm up, it'll never work to power these off of these small inverters. Because these fixtures won't be used regularly, it's easier just to run them from a old-school generator set
I don't understand how they manage to power entire industrial halls with these, they're fused with 16 amps per phase and that's like almost nothing, the fuses should theoretically blow from the apparent power on startup. It's absolutely ridiculous to have these installed in a small factory hall like the place I got these from, fluorescent lights would have been much more energy efficient and provided more than enough illumination, heh. There is 76 of these installed in that hall, so that's a insane power draw. They've all been retrofitted with LED bulbs now, but even those use 165 watts each. And their lumen output is lacking compared to the MH bulbs. It feels like the power usage just for lighting alone, the cost of that, far outweighs what they earn producing their item.........
