I was actually pretty impressed with the divergence of these diodes. I had thought they would be much more divergent. Comparing with the M140 it is about half the line size using a DTR-G-2. 

Here is the spot compared to a M140 diode. It is about half the size. Lens DTR-G-2

These can be pushed very hard before they drop off. 

I don't know what kind of life to expect or how they deal with switching when over driving with higher currents but looks pretty promising.Â
