Double-Ended HPS Grow Lamp
June 8, 2018
Double-ended (DE) bulbs and fixtures are the next-generation evolution of HPS (high-pressure sodium) lamps. If you are gardening under lights intensively in your home, especially if you're using grow tents, DE HPS lamps can be a good plant lighting choice. DE HPS lamps were originally designed to be compatible with traditional DE MH fixtures. A DE HPS lamp connects to a fixture on both ends, similar to fluorescent tubes.
Double-ended (DE) HPS lamps can also have a longer life span than single-ended (SE) lamps. Manufacturers claim that DE lamps produce 10 percent more PAR than SE HPS lamps, and that they also provide more UV and IR light.
