Using the online flashlight
The control changes the gray level drawn by this page, not your device’s hardware brightness. Opening the light covers the page; Escape or a click returns to the tool. Your camera flash is not used.
A worked example
At 50% intensity, the page draws RGB channels of 128 out of 255. At 100%, the screen is white.
Before you use the result
Actual brightness depends on display settings and hardware. The tool does not control the camera LED or keep the screen awake. Avoid shining a bright screen into your eyes.
