OK, while waiting for the circuit board to be ready, I have also ordered the SSOP to DIL adapter. In the meantime, its time to fine-tune the electronics. I have done this design late least year but because there were no physical model for me to design the PCB, it was kept on hold. I have, by this time, decided on the battery pack to be 4.5 volts since a White LED needs at least 3 volts to run.
