Waterproof Host Suitable for 445nm?

I was wondering if this host could be converted to house a 445nm M140 diode. I am wondering if the 'Waterproof Mirror' will work for that wavelength...

Also is a 18650 battery capable of driving a M140 for a while? Or would two CR123A batteries work better? If i were to go with the two CR123A batteries which driver would work best to convert the 6.0v to 3.7v?

That host would probably work, but would likely require a bit.more work that dropping in a green with driver and spring attached.

I wouldnt trust that tailclicky , its too soft for underwater pressure...

Maybe Water-resistant! But i wouldnt go too far and call if waterproof!
