Powerful LEDs reach 200 lm/W

Samsung has introduced two new white LED families in “chip-scale” packaging, at 1W & 5W power levels. The LM101B and LH231B packaging includes a TiO2 coating on the cavity wall, reflecting stray light back into the main beam. Efficacies range from 170 - 200 lm/W, and parts are available in a range of CRI and CCT ratings.
