I wasn't saying that if you put the 10 leds only over this tank that it would be. Equal to that 150w mh. Used a par30 bulb with 5 3w leds over a 10 gallon manor tank. And everything was fine my sps, lps, and bta. And the leds were driven at 2 Watts each. That's 10 watts and the par at the bottom of my tank was higher than the 150w de I had. The light is more focused with the lens. Creating greater par near the bottom of my tank. The 150w was higher up maybe 3inches higher. Even with the mh at the same height more heat was put into my tank But par was about 50 to 25 points higher near bottom of my tank. Bug the trade off is I can run my lights all day instead of having my mh turn off during the daytime when temp gets above 82°.
