Oops! Sorry, just calculated my cost for a 2 ft full spectrum DIY build costing me about $120. If u know where to source for quality led, you can get it done for about $200 or less. There are other led which is still reliable compared to high end LEDs at lesser price. Taiwan/Chinese made EpiLed and Epistar are also widely used in DIY LED fixtures and led cost are cheaper . It may not be as consistent in quality as those high end LEDs but is sure to get the job done. Do some search and you'll find that not all reefers use high end LEDs and yet get results. I've done DIY for freshwater planted tank using No brand Chinese made led and it made my plants pearl like no tomorrow and growth was amazing. It may or may not be the same for reef but it doesn't hurt to try. Will update my build on DIY section in time to come. Taiwan/Chinese led LEDs are not all bad after all.
