The new “TL1L4 series (4A5B type)” achieve a high luminous flux of 140lm(min.) [1] compared to the 130lm(min.) of conventional general products of the “TL1L4 series”. The 4 new products are in correlated color temperatures (CCT) of 6500K/5700K/5000K/4000K with a color rendering index of Ra70. The new products make it possible to achieve market requirements of lighting fixture efficacy over 110lm/W[2], and can contribute to improving luminous efficacy and lower power consumption of LED lighting applications.
