If you are going to go for w of the par38's why not just get a single fixture? The chines led
panels from ebay and amazon are around $100 and would let you keep anything your heart desires.
Another option is the current orbit leds, I have one over my 40b and it looks awesome. Almost double the cost of the tao chinese led
's though. Not too sure what high light corals the orbit can keep as well, I have mostly softies under mine with one stunner chalice that actually got burned cause the leds were too much for it.
