Seoul Semiconductor announced on May 12 the launch of its 120lm/W high-efficiency, SMD type LED for general lighting. The LCW100Z1 delivers over 120lm/W with an enhanced primary optic including enhanced heat transfer and the metal substrate, according to the company, while the pricing of the LCW100Z1 is comparable to similar-sized Chip LED’s that can tolerate only half of the current.
