Thanks Brad,
All I know is the part number is UPC25020. I have searched the internet seriously for hours and cannot find any information on the ballast at all.
It is strange. So are you telling me that it would be impossible to run the 250W bulb? If the ballast was rated 2x250W, would the 175W bulb still not turn on? I was thinking they somehow gave me a more powerful ballast with the hood. As for the only one bulb per ballast, I did not know that. I'm sure Ive seen setups with 3MH bulbs and only one ballast. Although, I've been wrong about many a fishy matter before.
well, At a very minimum, I could at least change the 175W 5500k to a 175W 10000K, correct?
