And yes, I said "ain't". :-) Some LED datasheets specify both continuous and absolute max ratings -- are you sure that's not an absolute max value? Perhaps the mfgr got it wrong on the datasheet...(very possible). The absolute max would be for a very very short time (milliseconds or thereabouts). -Neil. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
