I'm looking to upgrade to MH lighting and am considering the 250W e-ballasts. Which brand is better, Icecap or Blueline? Also, are the e-ballasts worth the extra cost? I am willing to pay the extra $$ if they can really run at a lower temperature and use a little less electricity. They also claim to extend the life of the bulbs as well, which would be nice. Are these claims true? Thanks!
