When reigniting the lamp after shutting down, please wait 3-5 mins to give time for the lamp to cool down.3.Ballast should be the same watts as the bulb at first use, or it may blow your bulb. The extra setting is to adjust the brightness of the bulb (lumen). Different lumens have different effects on the plants.
