Hello All,
Where can i buy Eletronic Ballast for my Metal Halide Bulbs in Singapore , its OSRAM 150W 6500K . has any one tried using this , if so any positive results in the reduction of Power Usage ?

Hi vraghu,

The electronic ones as far as I know is much much quieter than the cheap magnetic ones. It is a prized quality for people who value silence. (I can say this because I have six magnetic buzzing at my tanks).
Taken from winkipedia :
Just doing simple analysis of the statement it seems that e ballast does improve the efficiency of at least (but may not be limited to) your fluorescent lamp.Electronic ballasts usually change the frequency of the power from the standard mains frequency to 20,000 Hz or higher, substantially eliminating the stroboscopic effect of flicker (100 or 120 Hz, twice the line frequency) associated with fluorescent lighting (see photosensitive epilepsy). In addition, because more gas remains ionized in the arc stream, the lamps actually operate at about 9% higher efficiency above approximately 10 kHz. Lamp efficacy increases sharply to about 10 kHz and continues to improve until approximately 20 kHz*(IES Lighting Handbook 1984). Because of the high frequency of operation, electronic ballasts are generally smaller, lighter, and more efficient (and thus run cooler) than line frequency magnetic ballasts.
Thanks for the Update Medicine Man
E-ballasts are suppose to be more efficient than the magnetic ones. They should consume less energy (at start up) and prolong bulb life. If you want more information on e-ballast, you should do a search on salt water forums like reef central. FWIW, I'm replacing my Giesemann Nova II with e-ballast soon.
