I was wondering if I should get an LED flashlight to use while using my computer at night or an incandescent light? I surf the net a lot, word processing, I am getting into photography a bit more but only use iPhoto. Do I need the higher end LED lights or will an incandescent suffice? And, when will the next significant update to LED lights be coming out? I just don't want to buy now and then have a new set come out a week later.
