Yes, you’re allowed to change your mind—at least when it comes to MH and HPS lighting. Although the two fixtures use what are normally incompatible ballasts, conversion bulbs will let you switch lighting types. Some conversion bulbs allow MH light to work with HPS ballasts, and others let HPS work with MH ballasts. You won’t have the expense or work of changing or adding fixtures or ballasts—just change the bulbs. So, for example, if you want to use an MH bulb that boosts red and blue wavelengths in your HPS fixture, it’s possible the minute your bulb is cool enough to change out.
