What is a double ended bulb?
This relatively new technology in HPS and MH lighting has quickly become the go to for HID lighting. Double ended, or DE for short, utilize a different design, where wires on either side of the bulb attach to sockets in the reflector. Single ended bulbs still use an Edison type screw in, and thus SE and DE bulbs are not compatible. DE bulbs range between 600 Watts-1000 Watts, and generally include a specific ballast and reflector with the bulb.
Are double ended grow lights better?
Growers find that double ended grow lights emit more powerful light, and in a larger quantity. As mentioned earlier, these emit 10-30% more intense light than SE bulbs, while simultaneously emitting more Ultraviolet and infrared light. DE grow lights can result in yields 20-50% greater than an indoor garden with an SE light. The high frequencies these lamps run on lead to a higher level of efficiency, saving money on energy bills as well. DE grow lights also have a significantly longer life, as even after 10,000 hours of use, efficiency only drops by 10%.
If you have a smaller indoor garden and space is tight, we recommend a single ended grow light, as DE grow lights require more space between them and the plants due to the intensified light.
