Had my MH lights for over a year now and I am beginning to shop around for new blubs and I have a question.
What does it mean when it has "Radium" after the bulb description? Is Radium just a brand like Ushio or Iwaske?
Also in everyone's exerpience is there any manufacturer I should stay away from? Im pricing 150w HQI bulbs.
