Sunning your balls

[bartp401]

Cliff mentioned that you sound your balls for 10 minutes around 10 am.

 

I found a red led flashlight on Amazon:

Brand: AuKvi

4.5 out of

Deep Red Light Flashlight 670nm Single Mode Long Range Red Hunting Flashlights Torch with Zoomable for Astronomy, Aviation, Night Observation-Black.

 

I wonder if 670nm red led is the same spectrum of light that would work.
