Seoul Semiconductor Acrich COB line up

These new products are based on Acrich technology, which is Seoul Semiconductor’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.
