My 14-140 arrived today and with it an LED video light as per photo. It is $70 at Adorama and has a rechargeable 5V/3700mA LiIon battery. It recharges from AC or USB (all supplied). It came ready charged which was a nice surprise as I don't have a US/Aust AC adapter. The USB must be powered and comes as a twin cable so you can use two ports for faster charging. Tried it in my office with lights off and it worked well. Have to test the range a bit more. Construction is a bit light weight and the hotshoe attachment is not a good fit (probably OK on a videocam). At the price it was worth a play and of course it works for stills as well (macro maybe?).
