Most people think of their phone’s LED torch when they need a flashlight. It’s the obvious choice — bright, directional, easy to aim. But the screen itself is a fundamentally different light source: broad, soft, diffuse, and color-controllable. That combination makes it more useful than the LED for a longer list of situations than most people ever consider.

The flashlight tool here turns any browser tab into a full-screen light source with adjustable color and brightness. Here are 25 specific ways that’s actually useful.

Home and Daily Life

1. Finding Something in a Dark Cabinet

The LED points a hard spotlight into one corner. The screen held up to the opening floods the whole interior with even light. You see everything at once instead of hunting with a beam.

2. Reading a Handwritten Note or Prescription

Soft, even illumination with no hot spots is better for reading than a harsh point source. Hold the screen nearby for even, shadow-free light across the paper.

3. Checking on a Sleeping Child

Walking into a dark room with an LED torch pointed forward is a good way to wake someone up. Holding the screen face-down at low brightness, aimed at the floor, gives just enough ambient glow to confirm the child is fine without jolting them awake.

4. Navigating Indoors Without Waking Anyone

A screen at 20% brightness illuminates the floor and walls gently. No hard beam bouncing off white walls and ceilings. Enough light to walk without tripping, not enough to disturb a sleeping household.

5. Working Under a Sink or Behind Furniture

The LED in a tight space creates glare and shadows. The screen, propped at an angle, floods the work area with diffuse light from a broad source. Plumbers and electricians have been doing this with tablets for years.

6. Lighting a Pet Enclosure for a Nightly Check

Reptile tanks and fish tanks often need a gentle light check at night without the full overhead lights coming on. The screen provides soft, even illumination that’s less startling than overhead fluorescents.

Photography and Video

7. Fill Light for a Video Call

Position the phone running the flashlight tool slightly below your face and angled upward. It eliminates the harsh under-chin shadows that appear when the only light source is above you. Your caller sees a face lit from the front, not a dramatic underlit look.

8. Catchlight for Portrait Photos

A tablet or large phone screen held just outside the frame produces a beautiful rectangular catchlight in the subject’s eyes — more natural-looking than a round LED point source. Professional portrait photographers use this deliberately.

9. Product Photography Fill Light

Place a white screen on one side of a small product to fill shadows created by a main light on the other side. A second screen can substitute for a proper reflector or fill card. For more on screen photography technique, using your screen as a photography light covers this in detail.

10. Macro Photography Illumination

Photographing small objects requires getting the light source very close. The screen’s broad diffuse output prevents the harsh highlights that a point-source LED creates on shiny or textured subjects.

11. Low-Light Selfies

Hold the screen of a second device — or prop up a tablet — facing you while taking a selfie on your phone. The broad, soft light is far more flattering than the LED, which tends to flatten features and create harsh shadows at close range.

12. Color Gels Without Physical Gels

Set the screen to a specific color and use it as a colored fill light for creative photography. A warm amber screen as a background or fill adds a practical, controllable color cast without purchasing physical gels. For guidance on which colors produce which effects, light color psychology covers the specifics.

Nighttime and Outdoor

13. Camp Table Lighting

A phone or tablet propped screen-up on a camp table provides ambient illumination for a card game, meal, or conversation. No flashlight to hold, no harsh beam, no batteries beyond what the device already has.

14. Tent Ambient Light

A screen propped in the corner of a tent — face up or angled at the ceiling fabric — bounces soft light around the interior. Set to amber for a warm, comfortable atmosphere that doesn’t destroy night vision when you step outside.

15. Reading a Map or Trail Guide After Dark

Soft, even light across the page is more readable than a single beam creating hot spots and shadow. Hold the screen to the side of the map rather than above it to eliminate glare.

16. Night Fishing Bait Rigging

Tying knots and threading hooks requires close, even illumination. A screen held nearby provides the light without the harsh shadows a headlamp creates when it points directly at your hands.

17. Signaling Visibility in Fog or Rain

A bright white screen is visible from multiple directions simultaneously — no pointing required. In conditions where directionality of light doesn’t matter, the screen’s broad output covers more angles than the LED. This is the same principle that makes large lit surfaces more visible in poor weather than point sources.

Reading and Work

18. Late-Night Reading in Bed

The LED is a terrible reading light — directional, harsh, and guaranteed to wake anyone next to you. A screen at low brightness set to warm amber provides even illumination across the page without disturbing a partner.

19. Keyboard and Desk Illumination

Working in a dark room with a single monitor? Prop a second device screen-up near your keyboard. It illuminates the desk surface without adding glare to the main screen.

20. Inspecting Small Text or Fine Print

Screen light at close range, held at a 45-degree angle to a document, creates gentle oblique illumination that can reveal texture and embossing that flat overhead light obscures. Useful for reading embossed card numbers, checking serial numbers, or examining fine print.

21. Menus and Documents at a Dark Restaurant or Venue

Holding the phone screen under a menu at a dimly lit table is less intrusive than using the torch and less awkward than asking for more light.

Emergency and Safety

22. Power Outage Room Lighting

Set the screen to white at medium brightness and prop it up in the room’s center. For anything requiring longer use, battery conservation during a power outage covers how to stretch your battery across a multi-day situation.

23. Signaling Location in an Emergency

A bright screen is visible in the dark from a meaningful distance and covers 180 degrees of visibility. When compared against the LED torch, the screen’s omnidirectional output is a real advantage when you need to be seen rather than to see.

24. Examining an Injury

Even light with no hard shadows is better for accurately assessing a wound or injury than a harsh point-source beam. Color accuracy also matters when looking at skin tone changes, bruising, or blood color. Warm white or neutral white from a screen is more accurate than the cool LED torch.

25. Keeping a Child Calm During a Scary Situation

A soft amber or warm screen is less alarming than a harsh white beam and provides enough ambient light to make a dark, stressful situation slightly less so. Set it low, set it warm, and let it stay on — it will draw less battery than the torch.

One Common Thread

These aren’t edge cases — most of them come up regularly for a large number of people. The screen’s advantages (broad output, color control, softness, no pointing required) make it genuinely better than the LED for close-range tasks, people-adjacent situations, and any scenario where you need to illuminate a space rather than aim a beam.

The LED torch isn’t going anywhere. But the screen is a different tool, and using it deliberately — rather than just as a default fallback — changes what’s possible from the device already in your pocket.
