I am setting up a 36 x 24 x 24 planted tank. The MH lighting available here is Osram's " Power star HQI-TS, 150 W/D UVS, Daylight bulbs ( 150 watts )". I cannot get any further info on this except that the color temperature is 6500 K. Any Help regarding these bulbs is welcome with TIA. Madan Subramanian Bangalore, India.
