Horticultural white LEDs efficient at 3.10 μmol/J

Samsung Electronics has announced what the company claims is an industry-leading enhancement to its mid-power LED package, the 3.0x3.0mm LM301H for horticulture applications, such as greenhouse and vertical farming. At 3.10 micromoles per joule (μmol/J), the newly introduced 5000K LM301H now features the highest photon efficacy among today’s mid-power white LED packages, claims the manufacturer. This means lighting manufacturers can use 30 percent fewer packages in each luminaire to achieve the same efficacy level as the previous version of the LM301H, allowing for smaller and lighter lamp designs as well as lowered manufacturing costs.
