30" in depth is almost twice the depth of my tank (18").
In my opinion, higher powered LEDs (>3W) should be more suitable for you if you insist to keep your recent tank. If the intensity of the light (lumen) is not the main consideration for you but the penetration of light, I think these 1.25W LEDs that I am using now might still perform well under 30"! However, if lumen and penetration are both seriously concerned for your tank, the use of 3W LEDs or a shorter tank should therefore be necessary!
Here shows a demonstration of the LED fixture mounted on a tank with a depth of 50" provided by the manufacturer. One should notice that the LED fixture was mounted 10" above the water surface, which means that the real penetration depth is about 60".
With the blue LEDs (1.25W X 12) on:
With both white (1.25W X 24)and blue (1.25W X 12) LEDs on:
One can clear see that the whole tank was completely illuminated under the LEDs. Hoever, the lumen should be certainly decreased with the depth!
