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.
 
 The increased light intensity also enables this lamp to be positioned further from plant canopy increasing light footprint & light uniformity if desired. The PCA ceramic arc tube permits the lamp to operate at higher internal temperatures increasing colour rendering, output and efficiency. PCA resists interaction with the chemicals inside the tube which stabilizes the chemical mix over the life of the lamp, thereby improving colour consistency and PAR/PPF level maintenance.
