Question M140 Power chart for a 3 element glass lens

Hi LPF,

So I have searched around a lot for a power chart for a M140 with a 3 element glass lens and I only found the one in the attachment. I am trying to figure out what is the lowest current I would need to hit the 1.5W mark with the 3 element glass lens, but that chart doesn't go as high. I have tried to calculate the current but since the chart isn't linear (Goes up in a straight line) I can't (Well not yet ) calculate the accurate current needed to get 1.5W. I know the diodes differ a lot but can you guys maybe put up some different power charts (with a 3 element glass lens off course) that goes up to that power so I can make a guesstimate of the current? Thanks guys!

EDIT: Attachment attached

So this graph is underestimating the power?
