So I am running 400w radiums on both of my tanks. One on the tank upstairs and two on the 390. The bulb upstairs is right at one year and needs replaced.
Do different color temperatures produce more or less par. For instance does a 20k radium on same ballast and reflector produce the same par as a 14k ushio or 12500k geisman.
I am debating buying one bulb as experiment because I will need to replace 3 bulbs in about 1 year.
