Looking to purchase LED lighting for your reef or nature aquarium during the holidays? Before you do, ensure that the manufacturer provides the spectrograph for the unit you are about to purchase. PAR measurements are virtually useless for comparing LED lighting, one can only compare using PUR.
This is most easily done by comparing spectrographic data between diodes or fixtures. Any reputable manufacturer will provide you with either a spectrograph of their fixture or of the diodes they are using. Beware of those that only provide PAR plots or provide no info at all!
