Hey guys, this might sound dumb but are all 400W HPS bulbs compatible with all 400W ballasts or do I have to match up the brand of ballast with the brand of bulb?

NO... There are ballasts for HPS and ballasts for MH and ballasts that do both. If you have one that does both, it should work with any bulb.

Magnet ballasts are either for MH or HPS, but not both. Electronic or digital ballasts can power both MH or HPS. The brand is not relevant.

To be more specific...I have a digital, dimmable 400 watt ballast made by Apollo which can run either MH or HPS. MY question is do I need to use Apollo bulbs or can I use any other brand? Thanks
