The P9-XML2 was created to provide maximum yield and coverage with a single light in a 4’x4′ grow space. By combining our proven 12-band spectrum with 2x CREE XM-L2 10w booster LEDs in each cluster, we’re able to deliver increased intensity over a wider area. All of our XML2 series lights feature our new proprietary focusing lens system consisting of a one-piece, molded lens cluster featuring integrated 90 degree focusing lenses for the 3w LEDs and ultra-high dispersion 120 degree convex focusing lenses for the 10w CREE XM-L2 LEDs. This not only focuses and intensifies canopy penetration, but vastly improves spectral mixing and coverage.
