Enhanced Performance Philips HPS Lamps 600W *DISCONTINUED*
This bulb has been discontinued, and we recommend replacing it with the Gavita 600w Enhanced HPS Lamp that is made by Philips and rebranded under the horticulture company Gavita. 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. 600W Initial Lumens = 88,500 Color Temperature = 2,100 K Life Hours = 24,000+
