M140 Power chart for a 3 element glass lens

[Cube777]

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

attachment?

Awesome, thanks! I was looking for this the other day :beer:

the ratio is 1 mA to 1 mW for most m140's with a 3 element

the ratio is 1 mA to 1 mW for most m140's with a 3 element

So this graph is underestimating the power?

I have two c6's with m140's and mohgasm's 1.8 driver w/ 3-elements. one does 1728mw the other is at 1622mw. hope this helps you some.

Yea 1.6-1.7A should hit the mark for you.:beer:

Thans for all the repies! I'm going to run mine at around 1.65A
