Seoul Semiconductor Acrich COB line up

These new products are based on Acrich technology, which is Seoul Semiconductorโ€™s core LED technology for high efficiency direct AC driven LEDs. Acrich COB has two line-ups: MJT COB and AC COB. MJT COBs use integrated multi-junction technology chips and have a luminous efficacy of up to 168lm/W. They come in standard form factors with a single power connection. AC COBs use direct AC driving technology, which combines four groups of LEDs in a unique, solderable design. This improves design simplicity and the lifetime of the product by eliminating the external AC-DC converter.
