I am quite surprised by the brightness a 2ft fixture can offer... to minimize dark areas, I lifted up the left side to achieve a wider coverage... I then tilted it slightly facing to the front to focus the light to the front portion of the tank... the effect is quite dramatic actually with more shaded crevices to add a sense of 3D to the rockscape.
Will settle for this... for the time being
By using this light fixture, I manage to bring down my power consumption from 136 kW (10 tubes/4ft) to 29 kW (4 tubes/2ft) per month... that's more than 3/4 reduction :eyebrow:
The next challenge is of course depends on how corals such as LPS and softies react to the lighting. Will be able to find out pretty soon
I hope I didn't disappoint you guys too much
