Randy takes a look at the Orphek Atlantik V4 Compact LED light and puts it through a series of tests to find out exactly how many you need to cover your tank, how to mount them and finally share some BRS recommended light settings for spectrum. We also compare the output with that of a popular T5 only light as well as measure PAR to find out if this little LED can sufficiently light your tank for optimal SPS coral growth.
