The MXL8-PW40 is a 4000K Mid-power LED delivers optimized performance in combination with quality of light needed for distributed light source applications. In addition to delivering specified correlated colour temperature and colour rendering combinations, these emitters deliver the efficacy and lumen output required by the indoor illumination markets. It is tested and binned at 100mA, with current pulse duration of 20ms. All characteristic charts where the thermal pad is kept at constant temperature (25°C typically) are measured with current pulse duration.
