I was so undecided when i wanted to buy my halides. So i read and read. And based on my readings i decided that the iwasaki's was the way to go. Now i heard that they were yellow,green, etc. Well it's been a week so far and i am so happy i went with them. Mine are dual 250watt iwasaki's with 190watt acinics. Well the color looks a crisp white. I tell you its the closest thing to natural light. Just wanted to share that.....
