Based from my 6 months experience doing experiments on 3W LEDs,
For a 2ft deep tank, Average cost: P250 per 3W (this includes the cost of lense, heatsink, fan, adaptor, driver)
Assuming you need 2.5 Watts per gallon for SPS
2.5W x 35G = 87W / 3W * P250 = P7,250
For LPS at half the PAR
1.25W x 35g = 44W / 3W * P250 = P3,666
These are just estimates based on several LED builds that I have done. You can lower the cost by using unbranded Drivers, non dimmable drivers, unbranded LEDs, not use Lense if you have shallow tank, etc.
I'm not sure about the price of PAR38 but I think it's almost the same. The advantage of DIY is the dimming and you can separate the channel of blues and whites using 2 drivers.
Reef Masters: my apology for the ratios used for SPS and LPS. I may be wrong or maybe I'm almost near to being right on my assumptions.
Hope this helps
