The ASMT-MWE0-NMN00 is a derivative of the ASMTMW20- NLN00, a powerful and efficient 3 W white LED providing 130 lm at 700 mA. It differs from its predecessor by the addition of a diffusing layer that provides much better color homogeneity. This is particularly noticeable when the LED is used in conjunction with highly focusing optics. In this case, most of the white LEDs exhibit a color fringe effect with a bluish center surrounded by a yellowish ring. This unwanted effect is eliminated using a diffusing layer in the ASMT-MWE0. The ASMT-MW09-NLL00 (cold white) and ASMT-MY00-NJK00 (warm white) 1 W Moonstone are now available in increased light output versions. The ASMT-MW09 will typically provide 80 lm at 350 mA while, on the same conditions, its warm white counterpart will provide 50 lm. A warm white 1 W Moonstone LED with a typical light output of 65 lm (ASMT-MY09) is under development. Fine Color Temperature binnings are available from 4000... 10000 K for the cold white version and from 2600... 4000 K for the warm white color version. Both of them provide a high Color Rendering Index.
