Sheesh. Making me think at midnight, just before I go to bed. Honestly Hookshot. :P

To fill the metre, she needs one minute of direct sunlight with not breaks or shadows blocking her way. That is 2 minutes of direct moonlight, and 3 minutes of direct artificial light. When you take into account how quick a fight is in RWBY, she can pull it off maybe once, twice if it's a dragged out fight.

The length vs boost would basically be steps based off the maximum boost vs length. Maximum is 5x for 3 seconds, so 4x would be 6 seconds, 3x would be 9 seconds, 2x would be 12 seconds. As the duration for the maximum boost increase, so would each step down.

I would say no to energy or light-based attack like Velvet's light weapons, simply because while you can see them, you wouldn't be able to see by them. The light they give off would be too dim for her semblance to treat it as a viable source of light.

Fire and Lightning...well, the light they give off is technically natural, but nowhere near the levels of sunlight or moonlight, or even artificial light. I'd say that they give .5x the light for the purpose of the semblance, meaning that while it would take her 3 solid minutes to fill her metre on artificial light, it would take 4 1/2 minutes to fill her metre on fire or lightning.
