Default Can you use Camera Flash for a Flashlight?

Please Login to Remove!

Is there any programs available that let you use your flash on your curve for a flash light... i know many phones have a flash and let you do it... has anyone figured it out?

I've never seen any either. Rumors say that RIM is about to release a new 4.3 OS for all Curve users that will allow video recording - with the flash turned on if you want. Then you'll probably be able to "fake" a video recording just to leave the LED on.

I, for one, fear for the LED's durability.

RIM put a video recording length limit, so that shouldn't be a problem. If they use a good LED chip from Lumileds and CREE, those are quite durable -- it's the heat generated from a LED chip designed as a flash and not heatsinked enough, so the device should at least be engineered to have the LED on continuously, and deal with the heat that arises from it. (There's not much heat, but heat is LED's enemy). If they used a cheap chip and overdrove it, then durability can be a problem. Especially if the flash was never designed to be on continuously, and thus not heatsinked enough.

I've seen way brighter LED's though (ever seen a 5 watt LED? They're being used now in arrays in car headlights of certain really-new vehicles. Also, some traffic lights are starting to use arrays of 5 watt chips now, though most are using the 1 watt LED chips in arrays.)

I simply turn on the video camera and let it do its thing. No need for a program...

Looks like someone beat me by three minutes....

Don't know if you were happy with the other answers or not but you can turn on the video camera and then hit the space bar to turn on the flash. Nice bright light but not much range.
