Sharp, a Japanese multinational corporation that designs and manufactures electronic products, has launched new 17-mm chip-on-board (COB) Mega Zenigata LEDsthat come with 15W, 25W, 35W and 50W versions, and have the same footprint as previous versions of Zenigata LEDs. They offer luminous efficacy of up to 108 lm/W.
 
Sharp's GW6DxxxxNFC LEDs come in 2,700K, 3,000K, 3,500K, 4,000K, 5,000K, and 6,000K color temperatures with a CRI of 80 or more depending on the performance class.
 
The 50W version of the LEDs have an output of 4780 lm with a typical drive current of 950 mA. However, the design apparently allows users to can push the current to 1500 mA to achieve 6930 lm.
 
The lower-power products range in typical output power from 1600-3600 lm. Higher driver currents can produce 2480-460 lm. The LEDs have a minimum CRI of 80. Some of the products also have a CRI of 90 for applications such as retail lighting. The products reportedly deliver high R9 values for red colors.
