Online Flashlight

How to Use This Online Flashlight

Power out in the hallway and your phone’s built-in torch buried three swipes deep? This page gives you a big power button and two modes: real LED flash on phones that support it, or a full-screen white panel when you only have a laptop screen.

Pick Flash Light or Screen Light, tap the round power button (or press Spacebar), and allow camera access if the browser asks—only needed for the hardware torch, not for screen mode.

Online Flashlight Workflows and Practical Applications

Screen Light is like holding a lit sheet of paper under your chin—crude but effective for reading a label in a dark closet. Flash Light mode talks to the rear LED through the camera API; the video stream stays local and is not recorded.

When each mode fits

• Phone in a parking lot: Flash Light for distance; keep battery in mind—the badge shows remaining charge.
• Desk or laptop: Screen Light fills the monitor white; bump system brightness to 100% for best effect.
• Reading in bed: Screen Light with warm display settings elsewhere on your device reduces harsh blue light if your OS supports it.

Wake lock keeps the display from sleeping while the light is on, so you are not tapping the screen every thirty seconds.

Standard Units and Reference Tables

• Flash Light mode: Rear camera LED via getUserMedia; requires browser camera permission.
• Screen Light mode: Full-viewport white fill; works on any device with a display.
• Toggle shortcut: Spacebar or the central power button.
• Battery readout: Shown when the Battery API is available on your device.
