The Adjusta-Watt ECO Digital Ballast can be used in three different ways:

• You select the lamp type and wattage and the ballast will run the lamp to the exact specification that the lamp requires, just as if the ballast was dedicated to that lamp. It’s like having three separate ballasts in one unit!
• You can reduce the output of your lamp when not so much power is needed. For example, if you are running a 600w lamp you can reduce the output to 400w or 250w.
• You can boost the output of your lamp using the Over-Drive feature. This feature allows the output of the ballasts highest rated lamp (600w) to be increased by approximately 10% delivering maximum performance from the lamp.
