445nm for the 2nd time

Can you post a better picture of the raw output on a wall. From what I can make out that diode does not look zombied.

sure thing

Well it does not look like a normal zombie but it does not look right either. There is nothing on diode window?

 

[nosebleedXD]

diode window seems fine

so what exactly does not look right about it?

im still waiting for my 16340s batteries, i unno if that will make a difference

perhaps my cr2s are busted

Measure current flowing through diode with a dmm.

Its safer to use a test load to prevent an accidental short.

Depends on how you measure. However shorting isn't a problem with constant current drivers - they will just decrase voltage.
