difference in A130 and A140

[danielbriggs]

Are you referring to the datasheet for these specific diodes? I have yet to have seen a datasheet myself.. where can it be found?

Same as 9mm.
Very wooly; so could be more or less any blue 1W diode to be honest...

Sounds like same diode from different lots, Like the b - stock goes into the A130.
However also sounds like you could just drive the A130 a little harder to get to same power up to a point, A140 probably will do a bit more total power if driven to the limits.

However if just driving to about 750mW may just take a little more current.

Yes; or in two words that is slope efficiency
