I use 1 of Gavita remote ballast.. I like them better then the all in one units. I can use after market hoods(none cooling)that produce better par then the OEM hood did. Any ballast will fire the 400V DE bulbs but will not run it like it's suppose to. I did a test using a Matirx ballast it did not produce the same PAR as the Gavita ballast. There also inafficent compared to the GAVITA and E-PAP ballast.. I contacted Soilice-Tek they confirmed none of there ballast will run the 400v bulbs properly. If you want to use any DE 400V Bulb it must be capable to do that. Galxy turbo, Photom do no not provide the 400v the DE bulbs need according to there spec sheet. Lumatek does make 1 that will provide the 400v from there spec sheet...There are DE bulbs out now that do not need 400v to operate properly on any digi ballast . The bulbs are about 30$ cheaper..
