How do they retrofit hps to mv. Because I know you can’t just add the same wattage my bulb to a same wattage hps ballast. It will turn off before it gets to full brightness.

Typically you would have to replace the entire ballast but it looks like in this pic it was photoshopped to look like MV. You can see the NEMA tag while coloured blue, says HPS on the corner lol.

This is one of the fixtures they changed to MV for the movie Detroit that was filmed in Brockton. It's been confirmed that they did not change out any ballasts in any of the HPS fixtures. All they did was remove the HPS lamp and install a MV lamp and they all worked.
