battery stick on light

Common battery types include disposable AA and AAA cells, small button cells such as CR2032, occasional A23 cells, and some models use built-in rechargeable lithium batteries that charge via USB-C.

Brightness varies widely by model — examples range from about 1 lumen for very low-level lights up to around 500 lumens for high-output models.

Run time depends on the model and brightness setting. Examples include roughly 8 hours on high, mid-range runtimes of about 12–30 or 25–50 hours depending on mode, and some long-run units lasting up to about 100 hours on low or power-saving settings.

Some motion-sensing bar-style and similar models have built-in rechargeable lithium batteries. Those rechargeable units typically charge via a USB-C cable included with the light.

Options range from warm tones (around 3000K) to cool/daylight tones (around 6000K), plus basic neutral white LEDs; availability depends on the specific model.
