You make an error here: the LED that is used for this application is 
already invisible IR, otherwise it would fog normal films too.
And since #89B mostly affects/blocks the visible range (leaving IR 
unaffected), there won't be any gain at all....because there was no 
visible radiation to begin with....8-))
