Finally got around to pull out the old metal halide on the fish tank, and install the new LED lights. The new lights have a lower wattage (120W), but higher lumen. Thus in the long run, LED lights helps saving money on power usage. It also generate less heat. Comparing to the old metal halides, the PAR value is much higher, and the colors are whiter as well! It really makes the colors on the rocks and corals stand out. Overall, Hannah and I are really happy with this LED light fixture. The corals (the hitchhikers from the rocks...haven't got any new ones) were very happy with the light, and some of the corals are starting to show some color! At the present moment, I am running the LED lights on 50% of its full power, just to acclimatize the corals to the new light.
