Actually you're overdriving the bulb , bad idea all around. Additionally you may well wish to take a close look at what sort of RF signature that fancy digital ballast is emitting. If I have to elaborate on this factor say so. It would well behoove you to consider it.

If you wish to operate at multiple wattages it's a good idea to purchase the bulbs for each rather than overdrive or underdrive a given wattage bulb.
