Help Support CPF:

I've said I will do some low temp testing of the free-light. This will be low tech testing and I'm looking for suggestions on how to do this evaluation.
I am planning on leaving the light in my van and maybe at some point we'll have a temperature below -10.
How can I determine if the light is charged to it's maximum potential?
I won't be able to do a runtime graph but more look out the window and see if the light is on and how bright I'll use the binder clip method.
The other real-world problem will be the lack of sun in our winter but that is part of the real world up here .
Any advice on how to make this helpful would be appreciated. TIA
