stay the fuck away from both, niether will fire a hortulux bulb.I have two new six hundreds ,one has not been fired and the other has one nine week flowering on it.Buy a nice sun system, these things dont save energy and they are hotter than my sun systems,I sent two galaxys back because they would not fire the eye.If I can save one person this headache this would be good.Every good grower I know says they are not going to switch till they fix all the problems.Two local store dont carry gallaxy and one has lumiteck.My 600 lumitecks run hot and have been shutting down.I just switched back to the old faitfulls.Hydro wholsale wont fix them , they gave me lumiteck support and no answer for two weeks.Fuck LUMITECK
