Lenovo claims the keyboard will last up to 45 days in a completely dark environment before needing to be recharged. When the power is depleted, all it needs is 2 minutes of charging under a light source of 300 Lux intensity to get it back on for use.
This implies that you won’t really need much ambient light. That being said, I wouldn’t trust the marketing copytext.
300 lux is pretty bright. More than normal room lighting. So there needs to be sunlight getting in and wherever the keyboard is, it should not be too shielded from that.
Keep in mind that’s if it’s depleted it needs 300 lux for 2 minutes to start working when it’s fully dead. If it’s just sustaining itself it will probably get away with a lot less.
How much ambient light do they think users have near their computers?

In an office you’ll easily get over 300 lux.

I do not know how much it needs to sustain a charge. They don’t say it, so I do not assume it is better.
