wptski, the KL1 accepts an input voltage of 3 - 9V. The Pilas at 3.7V are ideal since the LED voltage is around the 3.5V mark and the KL1 has less boosting/bucking to do and runs more efficiently. The KL4 uses a boost circuit and presumably takes from 3 - 6V. The lower the input voltage the higher the current draw from the batteries. A 123 can't supply enough current to keep the KL4 in regulation, but a Pila can. A KL4 with Pila 168S will run for about 50minutes, so I have read. I estimate 35 minutes on a Pila 150S, regualted.
