i used this one http://www.dx.com/p/2w-9-smd-led-126-lumen-6500k-w... in this sample. using it almost 1.5 years. not bright as first day but still got enough battery to use it in emergency cases.

push-button was salvaged from an old pc case (probably power button) you can use something similar which in same size or purchase together with led module: http://www.dx.com/p/3-pin-push-button-switches-red...
