The previous posts mention that the Philips 5761 draws 5.4A and it will not work correctly with protected 18650.
All incandescent bulbs have higher initial spike which can be 2 or 3 times (depending on recalculated bulb life) of continuous draw which is about 15 Amps.
As of today, I haven't seen any protected 18650 to support this kind of initial spike. PCB simply shuts down the circuit to protect battery.
PCB of AW's 25530 protected cells was strong enough to work with Philips 5761 with single click but they are discontinued.
Solution is either pair of IMR 18650 or 2S/2P 18500 18650 system to share load of total spike.
