LightEnerG™ Super High Pressure Sodium Flowering Lamps are designed to outperform standard HPS lamps. They have a light spectrum shifted towards the red making them ideal during the flowering stage of growth with added blue spectrum for vegetative growth efficiency. Light EnerG™ Super HPS lamps provide more energy which is essential for optimized photosynthetic response. Lamps can be used in both the horizontal and vertical position with the appropriate HPS ballast.
