What is Double Ended
In the lighting industry, double ended refers to a type of gas-filled tubular lamp that has connectors on both ends, allowing it to snap into place on a fixture. This design feature distinguishes it from single-ended lamps, which typically screw into a socket.
Double-ended lamps are commonly used in HID (High-Intensity Discharge) lighting systems, such as HPS (High-Pressure Sodium), MH (Metal Halide), and CMH (Ceramic Metal Halide) lamps. These lamps are designed to operate at high frequencies, providing a stable temperature and operating current.

Double-ended lamps are known for their efficient light coverage and electrical use, surpassing that of single-ended lamps. They also require less maintenance compared to standard single-ended lamps. Additionally, they offer a substantial increase in light intensity and PAR (Photosynthetically Active Radiation) output compared to traditional single-ended bulbs.
The arc tubes of double-ended bulbs are typically shorter and thinner than those of standard single-ended tubes. This design allows for more light to be emitted from a smaller point, resulting in enhanced light output. Furthermore, double-ended lamps emit more infrared and ultraviolet light, which can be beneficial for certain plants, as it can increase potency and essential oil production.
