How is this not on-topic?
I'd love to see your set up.
Maybe what you need is a red LED battery powered light of some sort.
AAA batteries for LEDs last a very long time.
There are these wall mounting LED discs you can buy just about
anywhere. Cover them with a sheet of ruby mask, and mount four or so
in the space you'll be working on.

I have this really off topic question, there is a faint connection to
pure silver though..;-)..
Since a year or so I am quite heavy into wet plate collodion
photography, I'll spare you the details, but basically you prepare and
process a light sensitive plate with silver halides (see pure
silver..;-)..) in the field.
After exposure plates have to be developed immediately, so you need a
what is called a darkbox. Since the emulsion is only sensitive to blue
and a bit of green light you can work under red light. I am building
this box in my car.
Now my question is: how long can you run a low wattage (red) bulb from
your car battery before you drain said battery and are unable to start
the car again?
Thanks,
Best,
