600w digital worth the dough?

The answer is yes absolutely.these baby's will save you enough money in just the first year,you can finally afford to move out of the trailer park.and even take your girl to the local sizzler's i did.SERIOSLY they are electricly so much more andvanced and efficiant,compared to the coil ballest its apples and oranges.especially when you look at your electric bill after just a month.the digital ballest works something like a car amplifier it is able to make an almost exact amount of power with only the electricity that it needs instead of just slurrping the electricity down like a leach,and getting less efficint as time goes on like a coil ballest.see that is my favorite thing about them they are able to emitt a more connsistent amount of light over the course of the day.so if you ask me that should be the first thing you should buy with your crop MONEY!!!
