Keep this in mind when considering a ballast ....
I have a Sunlight Supply 400w Galaxy electronic ballast. It was purchased new from a reputable online vendor in March or '09. I have the invoice. The unit was not initially used, but was put into service in November of '09. For several months the ballast worked perfectly. Then, about a month ago, it began to flicker and dim. I phoned Sunlight Supply and described the problem and they told me that such symptoms were indicative of a problem with the ballast.
Since this product is advertised as having a 5-year warranty, I asked about return for repair or replacement. I was told to work through the original vendor to obtain a RMA number. The vendor obtained the RMA request form and sent it to me. I immediately filled it out and faxed it to Sunlight Supply. That same afternoon, the vendor e-mailed me to say that Sunlight Supply denied the request for warranty because the unit was manufactured in 2007. Call me stupid, but by my calculations 2007 to 2010 falls within the 5-year warranty time period. In fact, by Sunlight Supply's own admission, the serial number of 03012007400072 indicates to them that the unit was manufactured in March of '07.
Another request for RMA was submitted. This time including the receipt of purchase and the explanation that I was aware of the date of manufacture "coding" in their serial number. Sunlight Supply did not even give me the "courtesy" of a reply.
