There are a few new apps for the iPhone 4 that use its camera flash in a constant on mode to act as small LED flashlight. I dont have an iPhone 4 (yet) but was wondering if anybody here did. Curious to know around how many lumens it puts out. I looked at a few vids on YouTube, but I wanted the opinion of some LED experts.

I have an app on my 4 year old Motorola Q that does just that, uses the flash as a flashlight. It's actually much brighter than most of the lights I use and prefer. But that's not saying much because I consider anything over 10 lumens, bright.

They offer a similar app for the Droid, but since I'll always have a light on me if my phone is on me (if I'm wearing pants), I've never actually downloaded it. I guess what I'm trying to say is, I don't feel like I would actually use such an app. A friend of mine has it on his Droid, but he's not a Flashaholic like myself .

I would also like to know the lumen output on the white screen. Probably 25~30 lumens of floody flood light.
I just came across this gizmodo post today:

They claim that app has a strobe feature (PWM I guess) with adjustable speed, but I wonder how that would work for dimming the amount of light. It probably just allows a faster or slower strobe. I don't know.

Just ship it to Apple to replace the battery. :wave: No carrying spares, and directly a veto from me for serious use as a whole device.

I have a jailbroken flashlight app that's suppose to be brighter than earlier versions & it's ~5 to 10LM. Only used it once or twice to compare with flashlights.

Get it while it's hot, because there's no telling if Apple will pull this off the store or not... apps wired into hardware aren't normally approved.

Yep, I think the objection was it didn't use an LED so it didn't belong in the LED flashlights forum. I have no idea whether they use LED's or not. :shrug:

I fully admit that I'm not a "phone enthusiast" so I just don't get the somewhat recent movement to get cell phones to do everything besides just make phone calls. I see people going ga-ga over what their cell phones do and it just puts me to sleep instantly. :tired:
I know...different strokes for different folks.

I'm not a phone fan either, and I wouldn't want to replace my entire EDC with a phone, but, there is some logic in having features that can replace things you'd normally carry in your pocket, like camera, mp3 player, flashlight...
It's probably a good thing that a lot of non flashaholics who'd find carrying a flashlight around strange, will now have one on them rather than be left in the dark.

Moving this to Non-Flashlight Electronics, with the comment that this sounds a pretty quick way to wreck your iPhone battery...

I think all apps are "wired into hardware".
