Standard High Pressure Sodium lamps emit an orange/yellow color that is similar to the sun's spectrum in the mid day. This type of light promotes flower growth. However, the lack of blue spectrum light in Standard HPS bulbs can make a plant stretch during the vegetative growth stage. Enhanced Performance HPS lamps have a wider blue spectrum, which makes a significant difference in plant growth.
