thats a sweet deal! i run digital ballasts for the simple fact that they are really only juicing my powerbill hard the first three minutes of start-up. magnetic ballast would be alright if i was starting out from scratch, due to the cost overall vs. savings. imo someone could have a sweet garden with a very low start-up cost. i also really dig the fact that these lights are being recycled, or put to use, rather than melted down or landfilled.
