Ok, I have had this new diode for a few days, and it amazes me how well the host dissapates the heat, at the most the host gets mildly warm very evenly spread over the top of the host. This is impressive and a testiment to ehgemus's design considering how much heat the combination of the heatsink and the diode produce.
To compare this diode to others I have for anyone interested in it and as I was not familiar what 6watts plus would look like in the real world, it is very much like comparing the difference between my m140 diode at 2 watts to my NDB7A75 diode at 3.5 watts. When I first got my m140 I was using 301 lasers and it absolutely amazed me, it happened again with the NDB7A75 , and finally once again the sheer power of the NABM44 has awed me with its power. I guess that's why we love lasers and build them, they are amazing and to think so much power is possible in a handheld.
