the xenon burns too bright. You can't run a xenon for more than a second, it will burnt out, then you will have no xenon flash at all.
@max - Given a choice, what will you be choosing between a LIGHT - that is too BRIGHT or a LIGHT is toooooo dark (LED)

I don't care how bright it is, but when I say it "burns out" I mean that if you run the xenon flash for more than a second it will die aka never to be used again, even as a flash.
So IMHO, I'd rather keep my xenon in working condition, so that atleast it can be used for flash, and use the led for lighting my path. Anyway if the xenon flash could be used as a torch you'd run the batt dead in no time.
If the K750 LED is anything to go by, it's why and enough powerful to use as a torch.

I'm sorry, can a flash be used as a torch-light, even for a second? Flashes are capacitors that charge up and let go in a fraction of a second, are flashes used on phones any different?
LED's are useful in more ways than a flash, so i would pick a LED-only model but not a Xenon-only one. |

they are exactly the same. To keep one burning for more than a fraction of a second would use masses of battery power. Possibly the battery wouldn't be able to deliver power fast enough. Also xenon lamps actually burn out if left on for more than a second or two

if i'm not mistakened,the k850i has both xenon flash and led,so there might be an option to choose between one the two,that way you can overcome the overexposure problem...
EDIT:lol,we always say almost the same things at the same times!

Mabe because your headlights are halogen, not xenon  |

A xenon flash is a tube filled with xenon gas and no filiment, the length of the tube is closely related to the flash brightness. The longer the tube the more power is needed to fire the flash, this power can only be obtained with a capacitor which release's several thousand volts in a microsecond to bridge the gap in the tube.
The closest you'll get to a constant light with a xenon tube would be a strobe light, which, if your phone was capable of fireing the flash at speeds equivilant to that of a strobe your battery would flatten extremely quickly.

@ shaliron
Actually $herry is right, his (or her?) car does have Xenon headlamps, while not widespread, the adoption of Xenon High Intensity Discharge headlights can be found on high end automotive applications, such as BMW, Mercedes and Jaguar.

You learn something new everyday. Thanks 
I think I've noticed some of them on the road though. I personally find them extremely annoying - the bright white light is too bright compared to the more yellow halogen lights.
