Thread: Cellphone as a Flashlight

  1. #1

    Default Cellphone as a Flashlight

    I have seen flashlight applications before on my smartphone an HTC Desire which use the screen backlight. My phone software was recently updated with the 2.2 Android software Froyo, this came with a smart little flashlight app which uses the camera led to provide a flashlight with 3 different power levels. Should prove a useful addition to my phone.

    May even delay me purchasing a single aaa light as an EDC.

    Anyone with any experience of using their cellphone as a light in a tight spot?

    Upgrade your LED to a Rebel.

    honestly it's what most people do. And as you said the flash on a lot of phones is quite bright. A phone is also something you usually have on you.

    Downsides: not focused in anyway so its only good for close up applications. Also if you use up your battery using the phone as a flashlight then no more calls. Same reason I don't really like using my phone to play games or music or all the crazy things phones do nowadays.

    I have a couple of phones capable of doing this. I do not prefer the way it works.

    I have used it in the past (didn't have many pocketable lights until fairly recently), but found it very untrustworthy and clunky.

    It is not a very bright light in most cases. The only phone that does this for me is the Nokia 1650 which has a build-in light for this purpose only. It is acceptable, but my Fenix E01 (on my keyring) will most of the time be brighter and is a lot smaller to hold on to, even small enough to hold in my mouth when needing two hands.

    So, it might be what you are looking for, but for me it is only practical if I've forgotten a proper light.

    Like someone said it's what most people do. Like trying to use your keys as a pocket knife.

    I thought we were on this forum because we prefer to use the right tool for the right job?

    I think of the light in my phone as a backup to my backup EDC

    I used to have a phone with a single 5mm LED built in to it as a flashlight. Not a lot of light, but enough for, say, unlocking a door in the dark or the like. This was before I discovered CPF...

    Well after looking at how much light the iphone 4 puts out with the flash unit being used for a flashlight...I think it actually works, looked about 1-2 lumens directed light maybe more (didn't quite get close enough to my cousins iphone with my quark on low to compare) but way more light then the quark on moonlight.

    Last night, I was showing my GF my new AA Quark and it's moon mode. We later compared the lumen output to the screen output of my old school Nokia 2610 regular phone. It was very close in output.

    I use my phone screen to navigate into the bedroom before putting it on the charger to avoid waking up the GF who is already sleeping.

    Camera phones made into emergency flashlights sounds cool, but not very practical--yet. I predict in 2-3 years, your smart phone will light up as bright as a Quark on high.

    Yeah, that'll be the same week that we see these headlines:

    it's no replacement for an edc, but a good backup is great to have. this is what i keep around for those times. it uses the camera's flash led.

    I had a Sony Erricson W810i. That phone not only took the best pictures and made calls with ease, the flash LED was a pretty serviceable light. That was before I was a flashaholic, though.

    I have a Nokia E73 Mode. It has the flashlight function built in for the camera light. No need to download an app for it. When the phone lock is on, the keyboard space bar functions as the flashlight switch.

    Haven't had to use it yet - always carry my EDC on my belt.

    Every now and then I did this too, usually with the light of the screen, although my last two mobiles actually had an LED as camera light. But I don't use my iPhone4 for that task. For that, I still use my last phone since it acts as an alarm clock and its number has been the same the last 11 years (so everybody knows it) No iPhone would survive long enough near my bed if being used as an alarm clock. (And of course I am a flashoholic by now, so I have enough lights at hand).

    Cheers

    I have a Nokia N900 and the light is quite usable. Pretty even and makes a great light when you're reading a book in bed.

    It also has a good colour balance.

    That's the only time I use my phone as a light personally, I guess it never hurts to have another backup though.

    I've used this several times on my Motorola droid. Really comes in handy when u some how find yourself without a flashlight. Believe it or not I've used it to find a better flashlight when the power was out.

    There is no reason to be caught without a flashlight. That's just crazy talk!

    One of the reasons I got this cellphone is because the led flash is really bright, about 20 lumens.

    I now have an HTC Magic and HTC Touch Pro 2. I miss the LED flash that could be used as a flashlight on my old Sony Ericsson. It was pretty bright... about 20-30 lumens. I've always wondered if it would be possible to add a little atachment that draws power off my phones USB port and has a dedicated LED. That'd be sweet!

    My previous phone was a S/Ericsson K700i not sure about 20~30Lm but it was plenty bright to navigate by however it only remained on in short bursts requiring constant keypad activity to enable light output

    I have the samsung S5600 and I'm not sure what led it uses but compared to my H501 I'm sure it puts out over 80 lumens when taking a picture. The problem is that output only stays on for about a second, if you want permanent on you have to use it as a video light and thats only about 10-15 lumens. I guess it all comes down to heatsinking really..

    same.
    i have so many phones through the last 15 yrs. from startac to iphone4.

    the best ever phone led i owned was the sony c902. not only did it use a warm or neutral led but it was as bright as my h501w on high. it got pretty warm(steel body) and sucked down the battery pretty fast.
    i think cell lights are a nice backup though.

    The flashlight application has three power modes as well it really is quite effective as a backup.

    I have two on me a Nokia E63, momentary when keys locked, very fast and easy, and a 2 LED HTC Evo 4g, pretty bright for a phone. The Evo 4g, is smoking fast, Voice search, voice text, Google Goggles (Camera search and barcode scanner) 4-6-9Mbs, 11-12Mbs wifi. Wifi Hotspot for 5 devices, and satelite image gps that works indoors in a large building, LIGHTNING FAST. Everybody should have one.

    I tried it once to help me find the flashlight I dropped next to the couch after turning the lights off, but it didn't work for me and my feet found it first. Now I keep 2 flashlights next to the couch so I can still find one if I bump the other one around. I guess some phones must be brighter than mine.

    Got the Nokia 1650 since almost two years now.
    Can't say I use it as a flashlight, it's just a floody square for close distance. In pitch-black places it can show you the path, but only for a short time - the battery won't last long with this, as far as i have observed.

    Here's a quick beamshot



    Nokia 1650 left, Nitecore D10 Tribute / lowest setting on the right ~40cm distance from the wall. At 1m distance you barely see the Nokia.
    If you ask me - go and get a flashlight ! Safe your cellphones energy.

    Why shouldn't your phone have a flashlight built in? They do everything else. I just purchased a Samsung Captivate running the Android software and was surprised to find a guitar tunner application. I down loaded it and it works great. Flashlights, metal detectors, level, compass, GPS, oh and it is also a phone. Unbelievable.
