Total System Watts can be determined by locating the desired lamp in the first column along with the number of lamps required. The Input Power (Watts) column shows the requirements for both 120V and 277V installations. These figures are valid for any of the fixture series (i.e. RG, PG, ID etc.). In some configurations, multiple ballasts must be used (i.e. to use three 24w T5HO lamps, two ballasts are needed: add the input watts of both = 81w) Figures may vary slightly with ballast manufacturer.
