Larger die LED announced in April 2010 and first available in November, offering efficacy of 160 lumens per watt at 350mA. Output is 260-280 lumens at 750mA (bins T5 and T6), but can be driven to 3000mA for 910-975 lumens. Similar to the XP series, but a little larger, the die is 2mm x 2mm on a 5mm x 5mm substrate. The die has 6 strips with 3 bonding wires as opposed to the XP-G with 4 strips and 2 bonding wires and the XP-E with 3 strips and 2 bonding wires.
