    My iPhone 4 has a nice neutral (4500k or so) unknown led for the camera flash that can be used as a flashlight. I'll grab a beamshot for you tonight.

    Some low-end cell phones have dedicated flashlights (no camera and therefore no flash LED), e.g. Nokia 1208, 1280 etc.. Those LEDs are surface mount, not 5mm AFAIK.

    Low lumens, purple tints, weird optics and even weirder beam patterns, if you compare them to ordinary LED flashlights...

    Nokia 1280 beamshot (phone is perpendicular to the white wall, at a distance of approx. 1ft). Tint is more purplish than what is shown here. Note the beam profile:

    Amazing how cell phone makers try to cram about everything in their devices, from cameras, gps and flashlights to vibrators. And how people rush to pay "monthly plans" to use such, even while they're so crappy when compared to their standalone counterparts.

    I was handling one of my friend's giant brick cellphones and I was studying the flash which also served as the flashlight on the phone and it looked like it was a Rebel emitter... I think it was maybe a Nokia???

    As stated above, the flash on the iPhone 4, which can be used as a flashlight, has a nice, pure-flood, neutral tinted beam. I guestimate it to be in the 10-15 lumen range.

    I have a flashlight built into my cell phone (Samsung B2100). The beam has a very weird and awful shape and about a dozen different tints. But it has been very useful to me in the past. Like when I was on a holiday in Namibia, three Weeks in the middle of nowhere. I had lost my Qmini CR2 and my AA charger in the very beginning. My camera also takes AA-Batteries so I was really glad I had my cell phone light and didn't have to use the remaining charged AA-Batteries for my other flashlight.

    Recently I lost my new Qmini CR2. What I love about this flashlight (it's size) is also it's biggest curse. I know that it must be somewhere in my apartment but I just can't find it. As I am not ready to order my third (!) Qmini yet, I have to use my cell phone light as my edc.

    My Casio Ravine has a Very Low Powered Led flashlight, I am guessing its around 3 or 4 Lumens as it considerably Less than my L1Ds low(Which is 8 if I remember correctly).I guess it would be a good backup to find your EDC after it dropped out of your pocket probably nothing much more though.

    My phone is first and foremost a terrific phone, the sound quality when used as a music source is as good as an iPod or dedicated CD Player. The GPS is damn good, not quite on par with a dedicated unit but still excellent. As a camera it isn't too shoddy either:


    I have two interesting apps for it. One turns on the cameras flash led, which looks neutral. The other just lights up the whol screen in either red white or blue and you can adjust the brightness by swiping the screen. Being an Oled screen, the colours seem really pure and saturated.

    I wish my cell phone has flashlight, but it doesn't.

    I use a bright image as screen saver, I can set screen brightness to high, use it as a floody flashlight,
    find staff dropped on the floor of movie theater or find key holes at dark, its surprisingly bright.

    I have one of those cheap phones that have a built in flashlight. I'll try to get some beamshots and pictures of the light itself for you guys to examine.

    My HTC EVO 4G has a couple leds sitting one above the other right beside the camera lens. The phone has a built in app for using it as a flashlight. I was pretty suprised at the beam from this thing. Actually very smooth with a nice tint. You'd swear you were looking at the beam from a regular led flashlight! Obviously not the brightest, but if I was ever in a bind, it would be super handy.

    I think it's great that many people who would have never carried a flashlight now have access to one through their phones, even if it's no where near the brightness & quality of dedicated flashlights. One can hope that it would make it easier for them to realize the usefulness of a portable light.

    Of course, in an emergency, most phones don't tend to be waterproof, as durable, as bright, or have runtime like a real flashlight. Runtime especially suffers on many of these smartphones!

    I used to have a Kyocera candy bar style phone with a 5mm LED on the top for a light. It didn't work very well. My Droid X has an app to turn on the flash LEDs. They have a lovely neutral tint, and about 15-20 lumens of lovely pure flood. I just wish there was a way to adjust the brightness down.

    I also have a hand held two-way ham radio with a 5mm LED on top. It doesn't work very well.

    Most people do. I have often made the claim the sound quality from my iPod through my high-end audio system is as good as my well regarded CD player with it's dedicated DAC's for each channel. Since I know that no one who has listened to the two sources on my system could hear a difference, I digitally recorded the direct output from the CD player and iPod of the same piece of music and used edititng software to splice bits of both recordings together into a single track. I have posted the file and challenged people to download it, listen to it, and tell me the time points where they can hear the sound quality of the track change. No one has ever been able to do this. This Stereophile review of my ipod might explain why they couldn't: http://www.stereophile.com/budgetcom...934/index.html To quote John Atkinson "The iPod's measured behavior is better than many CD players"

    As I have said, my phone sounds as good my iPod or CD player listened to on either excellent headphones or my main system. here are the audio specs as measured by GSM Arena in their tests:
    Samsung S8500 Wave
    Frequency response +0.03 -0.04
    Noise level -90.9
    Dynamic range 90.9
    THD 0.016
    IMD + Noise 0.020
    Stereo crosstalk-92.5


    Now I could of course do as I have done for the iPod and record the output from the phone and CD player and make another file, but at this point i really can't be bothered.

    Despite what I assume are impressive photo & audio demos by cheapskate (& tam's beamshot doesn't look too bad either), I too disapprove of the trend you describe. But for me it's mostly getting pwnd by the in-your-face "No, you HAVE to get a phone that does _____!" guys, & those "big boy phone" song commercials, where the man can't get a job because of his old phone- the interviewer (& muppets) are laughing at him because he still has a flip-phone!

    Since the LED in my iPhone can not be exchanged as easily as a dropin in one of my hosts, I do not use it as a flashlight. But I stopped EDCing my Canon Powershot A510 finally since the iPhone4 picuture quality is good enough for most tasks. OTH, I actually have an iPhone because I want to check my e-mails and websites every few minutes no matter where I am and not because I want to talk on the phone (have to do that for a living 8-10 hours on workdays)

    Mine does (except for the brightness). Runtime is really good, it's waterproof and durable. When I go swimming, I just put it in the pocket of my swimming trunks.

    My HTC myTouch 4G has a built-in LED for camera flash or standalone flashlight, much brighter than a 5mm, though I don't know the brand or type for sure. It's decently bright, and even has a nice little app that looks like a mag light.

    Cheapskate:

    I won't bother here trying to discredit/ridicule the folks at S*phile. It has already been done to unbelievable extents in other forums.

    I will just point out that with a decent main system you can tell the difference between 90 vs. 120 dB S/N (easy with about any material) and 90 vs. 98 dB dynamics (with a good recording and knowing what to listen for).

    My Casio G'Zone Ravine has a decent little LED in the back, that has an easily accessible flashlight mode. It's probably a 5-10 lumen output, but great for finding your way around a dark room without stubbing any toes.

    +1

    My HTC Inspire is very similar and I too was impressed by the 3-level output flashlight app it has. Just as I use my HDS on low to navigate the house after my wife has gone to bed, she uses her flashlight app to do the same....since she doesn't carry at least one flashlight in her pocket at all times!

    I definitely would consider it a viable backup to the 2 lights I EDC.

    Gee, I'll just have to get myself a decent main system then, so I can hear all the things you can.

    It's a Samsung B2100. Not really a smartphone, but very rugged and cheap. Has all the functions I need and is really made for outdoor use. It actually has a second mic on the rear to record side noise and eliminate it from what the main mic records. This way people can understand you, even if you are in a hurricane.

    But, as already said, the beam of the flashlight is really awful. Yes, all the tints are real and so is the dark line going from the center to the edge. Blue in the center, yellow outside. You would think that there is a white transition zone but there really isn't.
