Mostly just European moguls will run in an HQI; like Giesemann, XM, Ushio, . Go to "Search performance data", then "by ballast", then select the 250w PFO HQI, and you will see which bulbs will run in it, and what their PPFD is. You can click on the bulb name, and it will show you the PPFD that bulb will give in each ballast as well.
