Cree LED XPGDWTx XLamp® XP-G3 Photophyll™ Select LEDs are designed to replace the white LEDs that are common in two-channel (white+red) horticulture luminaires. These LEDs offer an advanced horticulture spectrum with blue and green output tuned for horticulture applications. The XPGDWTx select LEDs maximize green content and minimize red content, and enable significant enhancements to luminaire cost and performance. These LEDs are entirely binned in horticulture metrics, allowing straightforward spectrum design without confusing translations or conversions. The spectral output of these LEDs is binned into two metrics. These metrics are based on the amount of PPF in standard blue (400nm to 500nm), green (500nm to 600nm), and red (600nm to 700nm) bands.
The two spectral metrics are the percentage of red PPF content (red PPF%) and the ratio of green to blue PPF content (green/blue ratio or GBR). These select LEDs combine this new color and the many strengths of the XP-G3 platform, including efficiency, long-term reliability, convenient design ecosystem, and optical control.
