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.
Bluenote Reviewed by Bluenote on . My digital ballast just failed mid 12/12 in the 1st week of flower. Bought a new digital ballast last week. Tonight it went off 6 times in total, over a period of 3 hours (about 2 minutes a time and for 5 mins while I removed the new lighting and put my old cfls back in). This is a stable strain that doesn't seem to be prone to stress (i have been growing it for 18 months). I think my girls will be OK, but I would be nice if someone who has had this happen to them, could provide some reassurance. Rating: 5
