Line 149: Line 149:


Introduced in February 2012, the XT-E has the same size chip as the XP series but seems to have a wider viewing angle for more flood and less throw. Can be driven up to 1.5A and available in bins up to R5 (at 350mA). This is a high efficiency LED capable of 148 lumens per watt at 350mA. The LED is not a flat square, but has an X shaped hill on the surface.
