M140s are listed as 445nm so no, probably not 450.

Taken from rhd's wavelength study
The M series seems to average high 440s, or very low 450s.

We shouldn't be calling M series diodes "445s". I've only run into maybe ~15% of the M series diodes that will even drop below 445 at threshold current, and ALL of those will still end up above 445 with any reasonable amount of current.

You cant tell the difference between 445nm and 450nm and diodes vary wavelength depending on current and temperature so M140 diodes aren't strictly 445nm.
