This Double-Ended (DE) pulse-start lamp has been engineered for use with Lumatek electronic ballasts and is produced using high-grade ceramic arc tube technology and specific horticultural gas blend that creates optimal spectral output for healthy plant growth.
 
Double-ended HPS lamps are more stable than traditional, single-ended HPS lamps and this allows them to have a 10% increase in light intensity and PAR/PPF output. The increased light intensity also enables the lamp to be positioned further from plant canopy increasing light footprint & light uniformity if desired
