The Metis XM LED is one of Pacific Sun’s newest high performance LED reef aquarium lighting fixtures. Thankfully the PAR readings for this light have finally leaked out on the interwebs and we have the above image to share with our readers. This chart is from a depth of 27″ and gives a great indication of the types of PAR values you can expect to have your corals under. As a reminder the Metis XM LED will have an even ratio of four different led types on board: Neutral white and cool white Cree XPG LEDs running at 5 watts and blue and royal blue Cree XPE running at 3 watts each. Now, if we could only get Pacific Sun’s CRP par values we would be really happy reef builders.
