Yeah i've never been an advocate of the 2W+ 445 builds either. I kind of figured it was only a short matter of time before they started dying. I personally think that right around 1.5W is probably the 'sweet spot' on these for life vs power.
Just be honest are they under 1k? I need to get some funds together if they open it up to everyone on LPF after the vet group buy. What's the output on these 50mw?
How does it compare to a 532 in the dark. Are they really brighter in the dark?
